Consumers are offered wall-hung, floor standing gas boilers with open and closed combustion chambers. In addition, you should also pay attention to the power of this heating device. The variety of modifications often makes it difficult for the user to choose, so it is worth detailing the most important characteristics.

Advantages

Numerous reviews of owners of private houses, cottages, garages explain the growing popularity of heating with cylinder gas the following factors:

  • Environmental friendliness and compliance with all state standards and regulations;
  • Autonomy and security of heating;
  • stability of operation and pressure level
  • economical fuel consumption and ease of operation;
  • possibility to heat water for household needs

Reasons for high performance

Heating from a gas cylinder has a high efficiency due to the fact that the energy carrier easily goes from liquid to gaseous state. Therefore, the heating system is fully independent, which gives owners of private houses or cottages can use it at their discretion and under any conditions.

The system of heating with liquefied gas is good in that it can perform two functions at once: to heat the house and provide hot water.

Nuances of use

Use space heating on gas cylinders will be possible even at the stage of construction of the house. it is convenient in the case of construction in the cold season. For safe use of the energy carrier it is recommended to follow certain rules of operation. For example, it is recommended to turn off the gas supply at bedtime or at least reduce it.

In addition, it will reduce the consumption of energy. Gas cylinders require periodic refueling: its quality must be paid special attention. Some staff stations do not fill the cylinders completely, so the owners are forced to overpay. be careful if you use the services of such stations.

Advantages and disadvantages of cylinder heating

Heating with gas cylinders in a private home. Yes or no?

You can heat your home in different ways. coal, wood, gas, electricity, solar panels. Practice shows that the most effective method is heating with natural gas. But not all homes can connect to the gas mains. What to do in this case? Some homeowners choose to heat with gas cylinders. In the article we will talk about the features, advantages and disadvantages of the method. Let’s find out how economically feasible this method of heating your home.

Filling gas cylinders

Gas cylinder heating of the house requires the constant availability of source of resource. In principle, for any type of heating system requires access to fuel, but in the case of gas cylinders, the case is somewhat complicated. If, for example, for electric boilers need only access to electricity, the gas heating requires the presence of cylinders. they must be regularly bought or filled.

In some settlements, there are brigades with workers and equipment for their delivery. Если же такой услуги нет, то покупать баллоны приходится самостоятельно, или же искать ГЗС для их заправки сжиженным газом (прочитайте: “Газовый котел на сжиженном газе: расход топлива на отопление”).

Regardless of whether or not there is an automatic boiler control system, it is advisable to turn it off at night in order to save energy.

What cylinders are needed for heating?

During the arrangement of heating systems in private or country houses, it is preferable to use cylinders with a volume of 50 liters. For their filling a special mixture of butane, propane is used, which under high pressure is in a liquid state. In addition, such combinations of fuels can be actively used to heat homes:

  • SPBTL. Is a technical mixture consisting of propane and butane. It is used for space heating in the spring as well as the summer period of the year.
  • CPBT3. Is a technical mixture that consists of such gases as propane and butane. Used for space heating systems mainly in winter.

Particular attention should be paid to the condition of cylinders in winter. Because even at subzero temperatures gas does not freeze. But in this case there is a high risk of stopping the fuel in the heating system. Boiling points of gases such as propane and butane are different. Propane boils at.40 degrees Celsius, and butane at 0 degrees Celsius.

Cylinders used for gas storage should be painted a certain color (orange or red). Also they should be specially marked with the date of filling and serial number. For storage of cylinders is prohibited to use basement rooms, as well as the basement floors of houses.

Required equipment for heating with liquefied gas

If it is decided to heat your home with liquefied cylinder gas, in addition to the basic equipment described below, you will need the following details:

A comb or tee is needed to combine several cylinders;

Check and drain valves, emergency shutoff valves.

Heating boiler

Boiler heating with LPG is used usual, intended for burning gas (gas heating boiler). This can be a wall mounted gas boiler, and mounted on the floor. The only thing when buying is to choose the most economical option, for example, a condensing boiler, it will reduce the expense of such a cheap fuel.

However, the standard gas boiler needs a little modification under the conditions of working with bottled gas. This applies to burners, they are replaced by special ones, and as a rule, they are included in a complete set of heating boiler.

Pressure reducer

In contrast to the main gas, the pressure in the cylinder gas system is constantly changing, depending on the temperature, amount of fuel and some other factors. That is why you need a gas pressure reducer for a stable and constant pressure.

The pressure reducer is chosen based on the requirements of the gas boiler. Reducers currently produced, allow you to regulate the pressure in the following values: 32, 37, 42 and 50 mbar. The boiler heating requires a constant pressure provided for a particular model. At low pressure the burner may not even light up. At high pressure can not withstand the elements of the boiler, which would lead to an accident.

When buying a reducer should not take a regulator designed for cooking stoves, its power is not enough to power the heating boiler, even the most economical.

Cylinders

For the heating system of a house on liquefied gas will require several cylinders, connected by comb, with the subsequent attachment of the reducer and connection to the boiler. For a house of 80-100 square meters one would need about 8-10 cylinders.

It is possible to create two cylinder groups used and a reserve, in case of an accident or a sudden run out of gas in the main group.

Cylinders are installed outside the house, in a special metal cabinet, well ventilated. The gas pipe from the cylinders to the boiler should be as short as possible in order to minimize pressure losses. As a rule, 22 kg of LPG or 40 liters of mixture can be placed in a 50 liter cylinder. Such underdrawal is done for safety reasons.

Propane heating. The most popular option

Among all the heating options today we can highlight the systems operating on gas, because they have gained wide popularity due to their functionality and ease of operation. over, heating with propane (this gas is the main in this method of heating) is used not only in houses, but also in industrial and domestic facilities.

If previously it was thought that it was impossible to arrange heating of the house with propane in case of remoteness of the building from the gas main, today this problem is solved simply: gas heating boilers function with the help of ordinary cylinders filled with propane, which allows you to mount such a system in absolutely any house.

What are the features of propane heating, as well as its advantages and disadvantages should be discussed in more detail.

The arrangement of cylinder heating

In the expanses of our country there are still remote from the main roads and the benefits of civilization plots with several cottages or houses. Is it possible to heat the house with liquefied gas from a cylinder in an area remote from gas communications??

There are no restrictions and prohibitions on the autonomous heating of an individual house with gas in bottles does not exist in principle. But heating with gas not from the central pipeline requires significant costs for thermal energy.

Home heating with liquefied gas is rational at:

The organization of home heating from gas cylinders can also be considered as a short-term solution, since in the future it is possible to convert the existing boiler for power from the central pipeline.

Heating a country house with liquefied gas is carried out with standard 50-liter cylinders. The vessels are predominantly filled with propane and butane, which are liquefied beforehand.

Gas heating can also be accomplished with such combinations of combustibles:

Cylinders must be constantly monitored in winter. Even at the lowest temperatures, heating gas mixtures do not freeze, but interruptions in fuel supply are quite possible, due to different boiling temperatures (for propane40°C, for butane. 0°С).

If you consider the temperature of.10°C, in a vessel filled with gas the mixture begins to boil, with propane vaporizing first. Before butane begins to boil, you can observe a decrease in evaporation in cylinder gas, which leads to a drop in pressure below the level required for normal boiler operation.

The best possible solution in such circumstances is to heat the cylinder to a temperature at which butane begins to evaporate. For this purpose, a corrugated hose from the boiler room should be led into the box. To transfer the heated air through the channel is necessary to use low-power channel fans.

Also when heating in the winter can organize heating pipes on the principle of underfloor heating.

Being in conditions of subzero temperatures in the country or in a private home cylinders in any case can not be heated with heating cables or heating elements.

Which boiler to use

Gas heating of a private house from cylinders is mainly carried out with the use of a boiler with a water loop as a heat generator. And fit any model boilers, designed for natural gas burning. For the normal operation of the equipment it is only necessary to replace the burner or adjust (replace) the nozzles. most boiler manufacturers include a special set for liquefied gases in the delivery.

Similarly selected type of heating device and its power. However, given the high operating costs of gas-cylinder heating should choose a boiler with the highest possible efficiency, for example, a gas condensing heat generator.

Boiler connection diagram

Heating of a country house with gas cylinders requires retrofitting equipment and purchase:

  • boiler;
  • Special nozzles for gas, if these are not supplied with the boiler;
  • reducer;
  • ramp;
  • shut-off valve.

Installation of cylinders in the basement or basement is not recommended, the best place for their location. made of metal box, the bottom and top of the front of which is made ventilation holes.

Tanks should be placed strictly horizontally, storage of full tanks in a vertical position is not allowed. The box should be placed on the northern side of the building, if possible in the most shaded area.

For normal operation of the heat exchanger is necessary to connect it to the “battery” of 4-5 cylinders for heating. Their installation and connection is performed according to the following scheme.

For the arrangement of the gas outlet pipe is used with a pipe with a wall thickness of 2 mm. At the point of its passage in the wall is installed sleeve with a diameter greater than the diameter of the pipe at 20-30 mm. The space between the pipe and the circumference of the thermowell is filled with assembly foam.

The vessels are connected to the system using a pressure reducer, which returns the gas from the liquid to a vaporous state, for subsequent supply to the boiler.

Connection is made in two ways: one common reducer for all cylinders or one device for each of the vessels. The second method is more expensive, but ensures complete safety.

To increase the interval between refuelings, it is better to connect several cylinders to the boiler simultaneously through a ramp. a double-arm manifold dividing the vessels into main and reserve bundles. The gas is first supplied from the main bundle, and when it comes to the end, the boiler is switched to a spare. When installing new, filled cylinders, the heater returns to power from the main bundle.

All connections are made in the form of pipes and hoses, detachable joints are checked for leaks by soaping.

Cylinders or gas holders

For gas storage in a liquid form gas holders are also used. steel reservoirs of large volume, which, unlike standard cylinders, are often enough for the entire cold period.

However, heating of a private house by gas cylinders seems more convenient, because there are no problems with the acquisition and delivery of fuel in any volume. In addition, to store gas in gas holders requires a significant amount of excavation work, which will lead to additional costs.

The disadvantage of cylinder heating compared to using a gas holder is the need for simultaneous connection of several vessels at once. The point here is not a desirable stock of gas, but that a single cylinder evaporation area is small and it can not give a powerful burner enough fuel. To heat a house, it is necessary to assemble a group of vessels at once.

What you need a reducer for

Cylinder pressure is a variable value that depends on a number of conditions:

A pressure reducer is used to convert and stabilize the gas pressure in the vapor phase.

Why I have not done this before !!! From a gas bottle

The device is selected according to two main characteristics:

Energy efficient heating of a country house with gas cylinders depends on the fuel consumption of the heating unit. In this regard, the productivity of the pressure reducer should not be less than the boiler injectivity.

According to the value of the working pressure, the device is selected according to the parameters of the heater. If the pressure supplied by pressure reducer is too high, it may damage the boiler automation, or you will see “separation” of the flame and fading of the burner. Pressure reducers are available in 30, 37, 42 and 50 mbar. There are also models in which this parameter can be adjusted in the range from 20 to 60 mbar.

High-tech pressure regulator

When cylinders are connected by means of flexible hoses, a pressure reducer with herringbone fitting is required; when cylinders are connected by means of combs and rigid pipes, fittings with threaded outlets are required.

In addition to their direct purpose, the gearboxes switched by automatics are equipped with protective elements. If the pressure rises to a critical level, protection automatically triggers by opening a pressure relief valve.
