Gas boilers from a cylinder (on bottled gas)

For heating a private house, gas boilers for liquefied gas must meet all the necessary technical characteristics, namely:

Power, which is decisive when heating a specific area of \u200b\u200bpremises, as well as the full provision of hot water supply.
Model features. There are many differences in the installation method, the closed / open combustion chamber, as well as the number of circuits.
Energy efficiency or efficiency. The higher these figures, the more you save when using such equipment.
Pressure. The lower the minimum indicators in the passport, the more rationally the fuel from cylinders will be used.
Gas consumption costs. Specific consumption figures primarily depend on the efficiency, power, and efficiency of the automated controls.

First of all, for each buyer, issues of gas consumption from a cylinder, the price of a gas boiler on liquefied gas for heating a private house and installation features have a special role this equipment. If you have specific questions regarding the level of energy consumption, minimizing heat loss, and so on, call and get professional advice from representatives of the Technodom company.

Prices for gas boilers on bottled gas (from a bottle) differ from traditional heating boilers, but it is still beneficial when it comes to heating a private house where there is no main gas supply. Buying a liquefied bottled gas boiler in the Tekhnodom online store is very easy, as you only need 1 click for this.

Today, autonomous gas supply systems are quite common, in which liquefied gas acts as the main source of heat. LPG gas boiler is quite popular technique. According to statistics, every year such equipment gains more and more fans who refuse in favor of safer, more efficient and affordable fuel from the main gas pipeline.

Affordable cost and convenience are exactly the qualities that are decisive when choosing a heating system using liquefied gas. But this list cannot be called complete. Consumers note among the positive features that there is also no need to maintain the described equipment. This distinguishes it from other types of gas boilers, some of which can make noise or form a huge amount of soot. That is why such devices require a separate room for installation, but only a professional can do such work.

How to choose a boiler for type and efficiency

On the domestic market today there are heating boilers operating on liquefied fuel. They are made by a variety of manufacturers. Each model is unique operational characteristics and cost. In order for heating to be more economical and efficient, it is necessary to determine the type of unit, taking into account the features of its operation.

A gas boiler for liquefied fuel can be classified as one of the varieties. Among the most common, single-circuit boilers should be singled out, which are intended only for providing heating needs. The second variety is double-circuit boilers, which allow you to equip a heating system and provide hot water. different models Designed for floor or wall mounting. The boiler can also be classified according to the combustion chamber, which can be open or closed. It is also important to take into account the efficiency factor. The higher it is, the more economically and rationally the equipment will consume fuel.

Boiler selection by power

A gas boiler for liquefied gas must be selected taking into account the power of the device. When calculating, the area of \u200b\u200bthe room is taken into account. Thus, for every 10 m 2 of heated area, 1 kW of thermal energy will be needed. In this case, the height of the ceilings should not be higher than 3 m.

This method of calculating power cannot be called accurate, but it helps consumers when choosing a unit. If you decide to purchase a gas boiler for liquefied gas, then you must take into account additional factors such as the quality of insulation, the size of doors and windows, as well as the presence of heat consumers.

Boiler selection by additional parameters

Gas boilers operating on liquefied gas should be selected taking into account the possibility of operating equipment at low gas pressure. Such equipment has a high level of efficiency. It should be in the range of 90% and above. If you do not have the opportunity to install a large gas tank, then you can use 50-liter cylinders. However, even in this case, at least two should be installed. For this approach, it is necessary to use special adapters that ensure the continuous operation of the equipment when moving from one cylinder to the second.

The consumer does right choice if prefers liquefied gas as the main source of power heater. If you purchase a solid fuel boiler, then during operation it will require human intervention, this should include adding fuel and cleaning. Concerning electrical devices, then their operation is possible only if there is a power supply from the mains. on diesel fuel are also not very convenient, because they cannot work silently, they produce soot, which quite often makes consumers think about replacing them.

Boiler selection by model: Rinnai RB-257 RMF

This gas-fired LPG boiler for heating provides a quiet start and high ignition reliability. Among the main advantages are:

reliability;
economical and efficient operation;
attractive design;
compactness.

Consumers, however, also highlight the disadvantages, the main one is the high cost.

Double-circuit boiler Rinnai RB-307 RMF

This equipment has a rather high cost, which is 52,900 rubles. The device is hung on the wall. Its power is 35 kW. The maximum heating area reaches 350 m 2 . The design has two circuits, one of them provides hot water supply, while the other provides heating.

Antifreeze or water can act as a coolant. Hot water is supplied in a volume of 15 liters per minute, this is true if its temperature reaches 40 ° C. The maximum gas flow is equivalent to 3.52 m 3 /h.

Conclusion

When choosing a gas boiler for liquefied fuel, it is necessary to choose equipment with more high power than the recommended level. This is due to the fact that the house is not always well insulated, and the ceiling height complies with the norms. In addition, if you choose equipment with power without a reserve, then the device will work for wear during severe frosts, which will quickly disable the unit.

The video shows how to reconfigure heating equipment for effective work on liquefied gas using the example of a gas boiler Vela compact 24 CTFS

You can organize autonomous heating of a private house different ways, gas boilers are most often used, but if the room is not gasified, then this option immediately disappears. What to do? You can consider solid fuel or, for example, electrical units as options, but it should be understood that in the first case, you will need to stock up on a large amount of solid fuel, and in the second, you will have to pay a lot for the electricity used. It turns out that both options are not the most profitable.

Recently, an increasing percentage of the population is opting for gas-fired liquefied gas boilers. The operation of such equipment compares favorably with safety, availability, and most importantly, high efficiency. Fuel can be used to operate the device from a special storage or cylinders. Advantages of the considered option of autonomous heating:

Gas holder for liquefied gas supply

During the combustion process harmful substances are allocated in a minimum amount, which makes it possible to classify the equipment as an environmentally friendly technique. Note that approximately 96% of emissions are carbon dioxide, which is utilized by plants;
High efficiency in operation, which is ensured by the efficiency, which reaches up to 97%;
The heater can be installed indoors, for example, in the kitchen;
The design of the devices provides for the presence of a security system and automation, which allows the equipment to be operated in the absence of a person;
To heat a house with an area of 100-120 m 2, you will need to use 1.5-2 cylinders (depending on the intensity of the system).

So, we note that a device for which liquefied gas is used has practically no structural differences from a conventional gas boiler. When the fuel is burned, heat is generated, as a result, the heat exchanger is heated, through which the coolant (water) passes.

A feature of the operation of the equipment in question is that it excludes the possibility of a malfunction when the fuel supply pressure is reduced, as well as in the installed injectors of a larger nozzle diameter, which are designed to work with liquefied gas

The principle of operation of equipment on liquefied gas

IMPORTANT! Many modern models of gas boilers provide for basic configuration the presence of injectors for operation on liquefied gas. Note that when switching the device from natural gas to liquefied gas, it is not enough just to change the nozzles, you will need to change the parameters on the equipment electronic board and reconfigure gas valve.

The uninterrupted operation of the boiler on LPG can be ensured if it is connected simultaneously to 3-4 cylinders or to a gas tank (underground tank), the connection should be made through a gearbox that is capable of providing a flow rate of 1.9 m 3 / hour.

Features of choosing a liquefied gas heating boiler

The first thing you should pay attention to is the power of the model in question, which is measured in kW. Note that for normal heating of 10m 2, a power of 1 kW is required, but provided that the room is well insulated and there are no big windows through which heat can be lost. For example, for a house whose area is within 100 m 2, it is enough to purchase a device with a capacity of 10 kW, however, in order for the system to work as efficiently and economically as possible, it is recommended to buy equipment with a small margin of 10-15%.

In addition to the power of the unit, it will be necessary to consider other points and characteristics, we note the main ones:

Efficiency, the higher the indicator, the greater the efficiency in the operation of the device; today models are offered whose efficiency is in the range of 93-97%;
Operating pressure. Devices for work, which use liquefied gas, are designed to operate at a pressure of 3-5 mbar. Note that the lower the gas supply pressure, the lower the fuel consumption;
Placement method. Today offered in the range of floor and wall options, which differ in functionality into single- and double-circuit ones, and can also have a closed, open combustion chamber in their design;

You can choose a heating boiler for the system yourself, but it is recommended to entrust this task to experienced specialists who will not only help you choose the device according to the requirements, but also install it in the heating system.

Features of equipment operation

Making a choice in favor gas appliance on liquefied fuel, it is important to strictly comply with the requirements regarding not only the installation of equipment, but also its operation:

It is strictly forbidden to install equipment in the basement, basement. The boiler room where the equipment is installed must have good natural ventilation;
The installation of the storage should provide for the presence of a normal entrance for a tanker car;
Maintenance must be carried out experienced craftsmen before and after the heating season.

IMPORTANT! The distance from the house to the container in which the fuel is stored must exceed 10 m, to the fence - 3 m, up to outbuildings-7 meters.

How to convert a gas boiler to liquefied gas

The main difference between equipment that runs on natural gas and liquefied gas is that the fuel is supplied under different pressures. So, in the first case, the equipment is set to supply gas at a pressure of 5-12 atm, if the pressure is lower, the sensor is triggered and the fuel supply is stopped.

For stable and safe operation of liquefied gas boilers, the equipment will need to be reconfigured:

- changing the feed rate;

- it is necessary to install a special set of jets;

- reconfigure automation.

Almost all modern models of gas boilers are able to work efficiently on both types of fuel. To change the operating mode, you will need to switch the operating mode and change the nozzles.

In the process of reconfiguring the device for operation with liquefied gas, it is necessary to set the minimum fuel supply pressure. Note that it is necessary to trust only qualified specialists who have the appropriate approvals to perform the necessary work.

IMPORTANT! AT technical documentation equipment is indicated minimum value at which the equipment can continue to function normally. The lower the score, the large quantity mixtures can be used from the fuel tank.

LPG nozzles

Quite often, users ask the question, why buy additional nozzles and replace them if the purchased device is capable of running on natural and liquefied gas? Therefore, we note that the re-equipment must be carried out for the following reasons:

After replacing the nozzles, which will allow the device to be switched from natural gas to liquefied gas, the operating pressure in the system increases slightly;
The main difference between nozzles for main and liquefied gas is different diameter nozzles;
For stable operation of equipment with a power of 10 kW, the fuel supply pressure should be 0.86 kg / h.

Jets / nozzles are sold as a set, recently modern manufacturers supply the necessary fittings necessary for transferring the boiler from operating modes in the basic configuration. If not, then you will have to buy it separately.

We calculate the boiler power

So, we note right away that everything is individual here, there are no clear recommendations. When choosing a device with respect to power, many factors should be taken into account. It is recommended to entrust this work to specialists who will do everything quickly and taking into account the established requirements.

But if you decide to save some money on the services of professionals, then you can try to make the calculations yourself. To do this, you need to know that for 10m 2 of a well-insulated house, 1 kW of liquefied fuel boiler power will be required, but this is provided that the ceiling height in the house does not exceed 3 meters.

When making calculations, one should take into account the total volume of the room, the presence / absence of insulation, the number and size of window blocks, doors. These are the main factors and parameters influencing the choice of device.

ADVICE! Opt for heating equipment of well-known world brands that meets modern requirements and standards. You should not save on buying a gas boiler for liquefied gas.

Features and nuances of the installation, connection rules

When performing installation, it is important to strictly observe and take into account a number of requirements. In principle, in 80% all work is carried out in the same way as in the case of the installation of a conventional gas appliance, but there are some differences:

Installation of a device that runs on LPG must be carried out in a room with an area of at least 8m 2;
The height of the ceilings in the boiler room is not less than 2.3 m;
The distance from any side (not front) of the boiler to the wall is from 0.7 meters;
The room should have high-quality natural ventilation, at least one opening window, a wide passage.

Provided that all requirements regarding the selection, installation and connection of the heater are strictly observed, further exploitation liquefied gas device will please with stability and safety, economy and efficiency in operation.

The lack of central gas supply, even in large regional and district centers, cottage settlements and other settlements, encourages all more people to look for alternative sources heat. An LPG boiler is an economical and reliable replacement option. Heating equipment designed to be connected to gas tanks or cylinder installations.

The difference between boilers for natural and liquefied gas

The principle of operation of a liquefied gas heating boiler differs from classical units in several features:

A gas boiler for burning liquefied propane-butane gas, in most cases, is universal and, after reconfiguration, can be connected to the main pipeline.

How to convert a heating boiler to liquefied gas

The main difference between natural gas and liquefied gas is that the former is supplied and burned at a higher pressure. Automation of conventional equipment is configured for indicators equal to 6-12 atm. When the indicators decrease, a pressure sensor is activated that turns off the burner.

The operation of a heating boiler on a propane-butane mixture requires a change in configuration and parameters:

It is necessary to change the flow rate of the gas-air mixture.
You will need to install a set of jets for liquefied gas.
Adjust automation to other operating parameters.

Modern single-circuit and double-circuit heating boilers are designed to operate on liquefied and main gas. Re-equipment requires replacement of nozzles and switching the boiler to another mode.

The technical conditions for the use of liquefied gas in individual boilers that are not designed for this type of fuel differ significantly. In addition to replacing jets, a complex reconfiguration of automation and control valves will be required.

It is difficult to correctly adjust the gas supply to the boiler when switching to liquefied gas, set the minimum pressure limit and perform other work on your own, without special skills. According to current regulations, all work must be performed exclusively by licensed specialists.

In the technical documentation of heating equipment, the minimum pressure at which the burner continues to work is indicated. The lower this indicator, the more propane-butane mixture it will be possible to use from a filled fuel tank. Usually, 15-30% of the total volume remains in the container.

LPG boiler nozzles

In the section on how to transfer the heating boiler to the consumption of a gas boiler on liquefied gas, it was mentioned that it is necessary to replace jets or nozzles. Refurbishment is required for several reasons:

Nozzles or jets are sold in sets. Some manufacturers, in the basic configuration, make all the fittings necessary for conversion. In other cases, the kit will have to be purchased separately.

What is the consumption of liquefied gas at the boiler

The volume of consumption of liquefied gas in gas heating boilers is indicated in the technical documentation provided by the manufacturer. For all models, it is different and depends on several factors:

Performance.
Burner type.
Equipment setup.

On the specifications consumption of liquefied gas is also affected by how the selected model is adapted for this type of fuel. On average, for a 10-15 kW unit, it will take 2 per week and per month, 9 cylinders.

Which gas is more profitable to heat - natural or liquefied

The comparative consumption of natural and liquefied gas during the operation of a heating boiler shows that it is more profitable to heat a house when the boiler equipment is connected to the mains. It is worth heating with a propane-butane mixture only in the following cases:

Changes in the design and reconfiguration of the boiler when using liquefied gas are temporary. It may take about six months from the start of registration and ordering a project for the installation of heating equipment connected to the main gas pipeline.
During this period, heat the room with electric or solid fuel heating equipment, specially purchased for this purpose, is not economically feasible. The cost of converting a conventional boiler to liquefied gas ranges from 500-1000 rubles.
Connecting a gas tank - in this case, the cost of using the mixture is more profitable than heating with wood, electricity or diesel fuel. The only condition is that the pressure of liquefied gas, adjust the operation of automation, must be reported by a qualified specialist. Incorrect settings lead to an increase in flow, approximately 15%.

The economic component, operational safety, the possibility of switching back to natural gas - all these factors make it expedient to use boilers running on liquefied gas.

Despite the fact that gas heating is the cheapest and convenient option space heating, in Russia there are still non-gasified settlements where homeowners have to heat their homes with wood, coal or fuel oil. If a gas pipeline is not connected to your house or cottage either, you can quickly solve the problem using a liquefied gas heating system.

Economic feasibility of switching to LPG

To assess the economic efficiency, you can use the method simple comparison liquefied gas with other types of fuel.

Natural gas, coal and firewood can be discarded, although they are considered to be the cheapest. The problem is that it's the lack of natural gas that drives homeowners to buy LPG, and coal and firewood are too much of a hassle to take the benefit of the savings out of the equation.

Let's compare the cash costs for heating a private house with an area of 300 square meters. m.

The prices indicated in the table may change, but their ratio remains the same.

As you can see, the cost of heating a private house with liquefied gas is significantly lower than if you used alternative heat sources for this purpose. You can find out how much gas the boiler consumes from the passport of the device, and how much gas heating will cost you - on your own, armed with these calculations.

Advantages

LPG can be used in any area. With the correct organization of the system, the change of seasons will not affect the autonomy of heating the building.

Autonomous heating of a private house with liquefied gas

From an environmental point of view, gas heating is second only to electric heating in terms of environmental cleanliness. Liquefied gas is devoid of all those disadvantages that are inherent in solid fuel- dust, burning, smoke.

And, most importantly, the durability of the system, which is due to the low wear and tear of equipment.

Flaws

Not without negative points:

the greater the boiler power, the more often you have to worry about replenishing fuel reserves;
at low temperatures, not the entire volume of gas is produced;
gas cylinders are a source of increased explosion and fire hazard.

The principle of operation of boilers on liquefied gas

Scheme of operation of a gas boiler

For heating use propane or butane.

Liquefied under high pressure gas is placed in a container that is connected to a reducer (this device lowers the pressure). The pressure drop leads to the reverse transformation of the gas from the liquid phase to the gaseous one. In this state, it enters the heating boiler, where it is burned.

Boilers designed to work only on LPG are not produced.

Any gas boiler is suitable for this purpose, only it must first be converted to liquefied gas. The article “How to choose a gas boiler” will help you choose a good model.

pay attention to important parameter boiler - it must be able to operate at low pressure (from 3 to 4 mbar). At the same time, the efficiency of the boiler must be high, otherwise heating ceases to be cheap, and therefore economically viable.

Otherwise, the choice depends on the tasks that are set for the equipment:

if the boiler is intended only for heating, you can purchase a single-circuit one;
if it must simultaneously provide the house with hot water, take a double-circuit one (see the boiler diagram).

Device connection rules

It is necessary to firmly grasp the following rule: the boiler must not be connected to a source of liquefied gas (gas tank or cylinder) without transferring it to this type of fuel. Otherwise too a large number of gas flowing through large diameter nozzles can cause equipment failure or even an explosion.

The transfer of the heating boiler to gas is carried out by replacing the standard burner nozzle with a smaller diameter sprayer.

Many models of gas boilers are equipped with such nozzles. The atomizer, as well as the burner, can be purchased separately. Some models also have to change the gas valve.

The gas cylinder is connected to the boiler through a special reducer that provides a gas flow rate of 1.8 - 2 cubic meters per hour. Conventional gearboxes are designed for only 0.8 m3/h, so they are not suitable for LPG.

If your device has two circuits, you can use these diagrams to connect.

Safety requirements

In houses with pits and basements LPG cannot be stored

Liquefied gas is considered safe enough, but only if certain safety measures are followed:

do not leave containers with LPG in the sun;
LPG storage tanks must be in good working order;
the air temperature in the room where the cylinders are located should not exceed 45 ° C;
Do not place cylinders in the immediate vicinity of radiators and gas stoves;
it is strictly forbidden to store gas containers in buildings with basements and pits. Propane is heavier than air and, if leaked, can accumulate in dangerous amounts on lower building marks, which can lead to an explosion.

Where to store fuel

Storage of LPG is allowed in cylinders, mobile and underground gas holders.

Gas cylinders together with collectors are placed in special steel boxes that can be mounted against the wall of the house, but on one condition: the fire resistance of the wall must be at least III degree.

Maximum allowable amount LPG in boxes - no more than 600 liters. When heating small buildings, 1-2 cylinders are allowed to be installed inside the house.

For heating a small frequent house or cottage, the use of mobile gas tanks is more productive.

The installation is a container with liquefied gas pumped into it (mini gas tank), which is mounted on a car trailer. The tank is equipped with a heating system, which is part of the general heating system. Mobile gas tanks are placed at a distance of 10 meters from a residential building.

For heating big houses stationary gas tanks are used - containers with an underground installation. Undoubtedly, this is the most the best option providing the heating system with gas. The container immersed in the ground does not require additional heating, and its volume can be selected in such a way that one filling is enough for whole year.

Minimum distances from LPG underground storage to a residential building:

10 meters - with a gas tank volume of 3 to 10 cubic meters. m;
15 meters - with a capacity of 10 - 20 cubic meters. m;
20 meters - with a gas tank volume of 20 - 50 cubic meters. m.

Owners of private houses can purchase liquefied gas at the nearest filling station. But "close" does not always mean "good": there are cases when people purchased cylinders with an unacceptably high water content. So sometimes it's better to go far away, but you will buy high-quality LPG.

Gas heating boilers, on liquefied gas (propane), video

Gas heating has been prevailing over solid fuel for quite a long period. Gas heating is very popular not only in various industrial systems, but also among the owners of private houses and cottages. Gas heating can heat both a separate room in a private house and an entire enterprise. Gas boilers for private homes are very popular, as they are relatively inexpensive, can effectively heat any building, and also stand out in a wide range. Gas boilers differ in their typical categories, which makes it possible for the owner of a private house to choose the boiler of the most suitable power. Such boilers are convenient in that with the help of them you can not only organize a heating system, but also a hot water supply system.

Gas heating boilers

Gas equipment can be divided based on categories such as installation method and location of the gas heating boiler. The main categories of boilers are floor and wall type devices. Such boilers differ not only in their functionality, but also in terms of design features and methods of operation.

Wall-mounted gas heating boilers, as well as floor-standing ones, can be produced with one or two circuits.

It depends on what functional abilities the boiler will have. It will be used strictly for space heating or will also provide home owners with hot water. Gas boilers stand out for their excellent heating speed, so you don't have to wait until you can wash the dishes or take a shower or bath.

Gas wall hung boiler

This type of gas boiler can rightly be considered a small separate boiler room. It contains all the heating elements and components, such as:

Burner;
Circulation pump;
Heat exchanger;
pressure gauge;
Safety elements.

Components of a gas boiler

Wall-mounted gas heating boilers stand out for their advantages. Firstly, they do not weigh as much as outdoor ones, and are more compact in size. Secondly, they are quite easy to install. All that is required is to connect the boiler to the pipelines and install it on the wall using fasteners. Typically, gas-fired wall-mounted heating boilers weigh no more than 50 kg. Wall-mounted gas boilers can be mounted even in a residential plan. Wall mounted boilers may differ in such a parameter as power. The most popular are boilers with a capacity of 12 to 35 kW.

If we take as a basis the calculation that for heating 10 square meters rooms need 1 kW of power, then wall-mounted gas boilers can heat a building with a total area of 350 square meters. meters.

Gas-fired wall-mounted heating boilers have some advantages, among which are the following:

They are compact in size and do not emit unpleasant and annoying sounds during operation. Modern models have the size of a small kitchen cabinet, and since they are hung on the wall, they will not take up much usable space, and will not interfere with the passage. The wall-mounted gas boiler is equipped with a special fan that reduces the noise of its operation, so such a device can be installed even in the bedroom.

Wall-mounted gas boilers can fit into any interior

Double-circuit gas boilers can not only heat the house, but also provide its residents with hot water. Such a boiler will be a more profitable purchase than purchasing a separate tank for heating water or connecting to a centralized hot water supply.
If all conditions are met correct operation wall-mounted gas boiler, and will also be produced correct installation, then such a device can serve the owners of the house for about 10 years or more. A wall-mounted gas boiler is relatively inexpensive, so it will good decision for organizing a heating system in a private or country house.
Easy repair and simple Maintenance. Due to its design features, in the event of a breakdown, access to any part of the boiler can be obtained from its front panel. To fix the breakdown, you do not need to completely remove the unit.

Gas boilers floor type

The main difference between such boilers and wall-mounted ones is that they will require a separate room to accommodate them, as can be seen in the photo. They also have higher power and are not as easy to install. Such boilers are more suitable for the heating system big house or businesses. The boiler room in which the boiler is installed must be well ventilated so that combustion products can escape from it.

floor boiler

An underfloor heating gas boiler is a device that has complex design. To install it to the heating system, you will need to install many additional elements. Despite the fact that such a boiler requires more complex installation, it stands out for its flexibility. Through such a device, you can create a heating system for certain nuances of a particular building or enterprise.

Floor boilers heating on liquefied gas can have a power of 26 to 60 kW. This means that they are suitable for heating a building of any size, as well as any enterprise.

Floor-standing gas heating boilers can have two circuits, which means that they can be used to organize a hot water supply system.

Such devices have the following advantages:

Flexibility. With this property, you can connect related components in a separate order.
Solidity and reliability. Floorstanding propane boilers are a separate heating system that will last for quite a long time and can be upgraded with various components.
High power settings. A boiler with a capacity of 60 kW can heat a production workshop or an entire enterprise. To do this, it will not be necessary to create a network of radiators or install complex additional pipelines.

On the video you can see the process of installing a floor boiler.

Heat pumps, their features and device as an alternative to gas

The principle of operation of heat pumps is similar to the principle of operation refrigeration unit. Their essence lies in the fact that they pump heat energy from one medium to another medium. Heat is taken from the environment through a special circuit. Such a contour is usually placed in the ground on the territory adjacent to the building or right next to the building. This heat is subsequently transferred to the building's heating system.

Such a pump is effective even in severe frosts, since the soil and ground water at a certain depth remain warm all year round. Since energy is consumed in small quantities only in order to ensure the transfer of heat, the pump can be classified as an autonomous component of the heating system. Heat pumps can vary in terms of power, so you can choose such a device for both a small private house and an enterprise with large area.

Principle of operation heat pump

Among the disadvantages of such a heating system, the complexity of its installation stands out. Another disadvantage is high price, however, it will pay for itself in a short time, since the pump does not need complex maintenance, and also does not require additional costs.

The main advantages of heat pumps include the following:

Economy and environmental friendliness. The heat pump does not need any fuel to operate, so it will not emit waste that could be harmful environment.
Simplicity of design and reliability. If you look at the design features of such a pump, it stands out for its simplicity. Several mechanical elements of which it consists are unlikely to fail in the near future, so breakdowns are extremely rare.
Autonomy and independence. All that is required for the operation of such a device is electricity. By means of such a heating system, it is possible to heat a building located in a remote area.
Easy to operate. If the installation of such devices can scare away with its complexity, then you should pay attention to the fact that such pumps practically do not break down due to wear. There is also no need to carry out their preventive inspection and repair, as the reviews show.

Heat pump

Features of installing heat pumps

From a technical point of view, installing a heat pump does not stand out as something complicated. However, the work associated with its installation is quite voluminous. If the heat pump belongs to a model in which the circuit placement is of a vertical type, then a well will need to be drilled with a depth of 50 to 100 meters. This must be done in order to achieve warm groundwater or a warm layer of soil. The ideal option there will be a heat pump installed before the construction of the building starts. In this case, the well can be drilled under the foundation.

If you are not afraid of the high price of such a device, as well as the complexity of its installation, then of all modern heating systems, this heating method will be one of the best. These types of heating systems have a great future, as every day they are becoming more and more popular.

Heating a house with liquefied gas - consumption and installation

A question of organization efficient heating individual home- one of the most relevant for owners of cottages and cottages. Despite the variety of existing methods and designs, liquefied gas heating is still distinguished by its simplicity, but its economic efficiency must also be calculated.

Gas cylinder system for LPG heating

Opportunities and advantages of autonomous gas heating with propane

The main criteria are the complexity of installation and the costs incurred. Of the equipment needed to heat a private house, we need:

in fact, the selected model of a gas boiler for liquefied gas;
burner;
gas pipeline;
gas reducers;
liquefied gas cylinders.

Homeowners can use both single-circuit and double-circuit boilers, including heating. Otherwise, you will need a separate water heater installation. Boilers can be used different capacity and power, with different options execution. Most of the manufactured boilers can be successfully adapted at home for liquefied fuel, one has only to change the burner. Another factor when choosing a boiler is the pressure it creates: for maximum gas flow from the cylinder, it is necessary that it be as low as possible.

The efficiency indicator of the boiler (in the range of 90-95%) is no less important for working on liquefied gas, because it directly affects the feasibility of such heating in a private house. If we are talking about heating one or two rooms, then at home it is enough to use a gas convector, which does not require complex structural installation.

Gas cylinders connected to the heating boiler

The main advantages of using liquefied gas for heating private houses and similar premises include the following characteristics:

availability of system installation;
autonomy in operation at home;
unpretentiousness and high reliability;
low cost of a gas boiler;
proper installation and maintenance of the wall-mounted boiler makes it possible to extend the service life up to 20 years.

Installation of a home heating system

First of all, you should focus on connecting several cylinders to the boiler at once. It is most preferable to combine 3-10 cylinders into one complex at the same time. The connection of such containers to the gas boiler takes place with the participation of a reducer that could create the required pressure.

When connecting a liquefied gas system at home, you can install one common gearbox, or you can equip each cylinder individually with it, which is safer, although it is associated with increased costs. Several important tips related to the reliability of installation:

for installation, you need to choose a room without basements and various recesses, since the gas is heavier than air and will accumulate in the lowlands;
it is not recommended to install gas containers in rooms adjacent to living rooms;
for installation, it is best to choose a warm place, since at low temperatures the pressure decreases and the burner can turn off automatically;
it is more expedient to connect the burner with cylinders using a corrugated flexible hose.

Gas consumption of the heating system

Speaking about the efficiency of gas supply with liquefied gas, it is worth touching on the costs of its operation. The calculations in this case are approximately as follows: one gas boiler in a private house consumes 0.12 kg of gas per hour of operation with a capacity of 1 kW of energy. For a house with an area of 100 sq.m. you will need a 10 kW boiler with a fuel consumption of 1.2 kg per hour of operation. This is a fairly significant indicator, however, if the boiler is set up correctly, it will be able to consume several times less and at the same time provide a comfortable temperature regime. Wherein highest flow gas will be when the system warms up.

As practice shows, on average, from 7 to 9 kg of liquefied fuel per day will be needed. Since approximately 22 kg of gas is placed in one container, we find that we need 8-9 cylinders for a month.

To reduce propane consumption, there is a special automation that will lower the heating temperature at night. Thus, the gas cost meter allows you to achieve savings of 20-30%. For heating country house you can set the mode at the level of 5-10 degrees for the period of absence of inhabitants, which will cost only 3-4 cylinders per month.

When using propane necessary element homemade gas system should become a consumption counter. How heating system, and heating water will require much lower costs when measuring gas consumption. By using gas meter measure the volume of fuel passing through the pipelines. When purchasing a flowmeter, you need to focus on the direction of gas flow, which can be left- and right-handed.

Convector type gas devices

Another excellent standalone solution for home heating is a gas convector. It has a sealed chamber in which the combustion of the gas product occurs. The heat exchanger of the convector makes it possible to heat the air in the room as soon as possible. At the same time, it is quite environmentally friendly, because the output of combustion products from the tanks occurs through a special air intake installed outside.

gas convector heating

Such devices can operate on both liquefied and main gas. In addition, convectors can have either natural or forced circulation. The principle of its operation is quite simple: when turned on, the pilot burner is ignited, after which gas is supplied to the main burner. Exhaust gas, expanding under pressure, passes along the walls of the heat exchanger housing and heats them.

The convector temperature sensor closes the gas valve after the necessary heating and combustion continues only with the help of a pilot burner. As soon as the heat exchanger cools down, the main burner of the convector is switched on again. Thus, at a relatively low cost, this unit is able, regardless of the supply of centralized energy sources, to maintain the required temperature with the possibility of accelerated heating of the room.

How to heat water with gas installations

We were talking about heating, but household supply hot water in apartments, country houses and dachas - at least actual question. good decision can serve instantaneous water heater operating on liquefied gas. They have fuel flow regulators that allow you to adjust the water heating to the required temperature. In the country, with the help of a water heater, you can organize heating of water in the shower or for washing dishes. follow economical consumption fuel counter will help.

In Western countries, it is popular to store gas in special containers, with volumes of 50 liters or more, hidden underground. In the event of a complete absence of centralized heated water, a gas instantaneous water heater can become a really reliable assistant. For selection suitable model it is necessary to get acquainted not only with its capacity, but also with the indicators of the working pressure in the tank, which will affect the amount of water heated per unit of time.

LPG tanks installed underground

Many modern gas water heaters able to serve 2 water intake points at once. They are equipped with an open combustion chamber and automatic ignition, they accumulate the pressure necessary for uninterrupted heating, but they can also work in economy mode. Both natural and liquefied gas can be used as fuel.

Thus, domestic use for an autonomous system running on liquefied gas can be effective if equipped with a meter and heating rooms up to 100 square meters. For larger premises, it is more expedient to use main heating, which will be economically justified.

LPG boiler - pitfalls of use

An ideal option for heating a country or private house as an off-season heater would be boilers running on liquefied gas. The advantages of such boilers are high efficiency, economy and ease of use.

LPG boiler fundamental differences in the design does not have, with the exception of special nozzles, which can often be supplied as a set.

The difference lies in the fact that the nozzles for such boilers are made taking into account the impact of a stronger working pressure.

Tip: it is better to leave the work on setting up the boiler to a specialist, even taking into account that they are available in the performance of the average man in the street. Thus, you can be sure that the master will do all the work correctly and guarantee the quality, as well as the safety of connecting the boiler.

Advantages and disadvantages of such equipment

In comparison with others available options heating, liquefied bottled gas boilers have a number of undeniable advantages:

Independence from tariffs for housing and communal services and a centralized heating supply system.
The efficiency of boilers reaches 96%.
Versatility.

Versatility lies in the fact that the boiler can operate not only on a liquefied fuel source, but also on ordinary bottled gas. To do this, it is only worth changing the burner to a model with a smaller nozzle diameter.

Also, the second universal quality of such boilers is their functional practicality. That is, they can be used not only as heater but also for water heating and other household needs.

There are also disadvantages

For all their "positivity" and convenience, these boilers also have some disadvantages, characterized by 2 points:

The process of connecting each cylinder is done manually and requires not only scrupulous care, but also caution from a safety point of view.
For full-fledged continuous operation, it is necessary to have several cylinders of liquefied gas in stock.

Recommendation of experts: it is better to allocate a special ventilated room for storage of cylinders, preferably with a separate exit. It is strictly forbidden to store cylinders in the basement or basement.

What must be taken into account when choosing equipment?

First of all, you need to decide what functions the boiler will perform.

There are 2 types of modifications: single-circuit and double-circuit. The first ones are intended only for heating, and the second ones also allow you to heat water, in addition to heating the room.

There are also differences in the method of installation: wall and floor models. The combustion chamber can also be of two types: open and closed. It all depends on the preferences and convenience of the user.

When buying equipment, the first thing to focus on is the quality characteristics:

The equipment must operate under low pressure conditions. This will maximize the consumption of gas in the tank.
Efficiency should be at the level of 90 -96%.

Equipment with such characteristics will be able to fully justify the expected demands for economy and efficiency (consumption - approximately 2 cylinders / week for heating an area of 100m2).

In principle, if there is a boiler running on bottled gas on the farm, there is no need to buy another one. It is enough just to put nozzles with a smaller diameter and set up the automation system and fittings. For a greater guarantee of success, it is better to contact a specialist.

Calculation of the consumption of liquefied gas

When calculating the gas flow rate, one must be guided, first of all, by the evaporation surface area. The higher this indicator, the faster the liquid is converted to vapor.
