Home heating gas cylinders. Personal experience

Despite the fact that the market there are many heating systems, many Country residents would like to heat your home trunk gas.

However, it does not always have the opportunity to connect to the pipeline with the "blue fuel". If there is no gas and gasification your individual housing short term "does not shine" alternative is the liquefied gas from the cylinders ..

Is it profitable to gas cylinder heating

It seems that the gas heating system of a private house organized and easy. All that is needed - is:

• Purchase gas boiler. Most of the boilers on the main gas can run on LPG. For this purpose it is necessary to change the nozzle and, if necessary, reset the control system;
• Buy reducer, gas equipment and valves;
• Connect and configure the heating system.

The main issues that arise at any homeowner, think about the heating system with LPG:

• Will I be able to heat the house;
• How long can the boiler to work on a single tank.

Independent heating private house gas is best to organize, using cylinders for liquefied natural gas capacity of 50 liters.

Practical experience of members of the forum said that stoke private house gas from the cylinders - unprofitable, if poorly insulated house, and the building has a large heat loss. It is necessary to take into account the total area of ​​the country house. Heating with gas from cylinders cottage 150-200 sq.m. It can fly a lot of money.

In this case, the alternative could besolid fuel boilers.

Before you realize it worth it and will pay if gas heating system of a country house It must be read with the following information, which shows the economic feasibility of a given species heating.

1. Natural gas = 33 cop / kWh.

2. Elektrokotol working in conjunction with the TA (heat accumulator) at night tariff = 0,92-1,32rub / kWh.

3. Pellet stove = 1.20 -1,32rub / kWh.

For comparison, the heating efficiency of the liquefied gas is only 2.32 rub / kWh.

When calculating the effectiveness of a heating system must take into account that in the suburbs of Moscow and other regions may have their own priorities in the choice of fuel, which depend on its availability and climate conditions. Somewhere cheaper coal to heat the house, but somewhere in the wood.

When calculating the profitability of heating liquefied gas, many forget that the cylinders have to carry on refueling on average once a week, and this additional cost - both monetary and time. Therefore, heating the liquefied gas may be advantageous to subject 4 conditions:

• A small house area - up to 100 sq.m .;
• The house is well insulated;
• In the nearest future it is planned to gasify your village will be connected from the gas. In this case, heating the liquefied gas is a temporary measure that allows not to buy two different boiler;
• The boiler that runs on LPG, is a reserve and works in conjunction with other heating devices.

It is also possible to mount a bundle of electric and gas fired boiler.

Despite the increase in the cost of a heating system, an overpayment is a question not for the sake of economy, and to increase comfort.

In this case, partially eliminating the need to travel and fill the tank.

Features of LPG heating

For mounting reliable and safe heating of the liquefied gas it is necessary to understand the features which are due to the properties of the fuel.

The cylinders are filled with a mixture of propane and butane. This mixture, at high pressure, is in liquid state, which is necessary for its transportation. Also emoksti can be tucked in different fuel types - depending on the season:

• Technical butane (BT);
• summer technical mixture of propane and butane (SPBTL);
• winter technical mixture of propane and butane (SPBTZ).

Emphasis on gas cylinder heating needs in winter.

ElenaO: - We decided to heat the house 120 sq.m. via running on LPG gas boiler. Gas cylinders are on the street in metal cabinets. The plate is one, and the gas boiler is made of a bundle 5 of cylinders, but only 2 while plugged. By lowering the temperature to -2 ° C had a problem - the gas is not supplied, and the boiler, respectively, does not work. I think gas froze.

This occurs for the following reason. The boiling point of butane - about 0 ° C. The boiling point of propane -40 ° C. When the outside temperature -10 ° C propane-butane mixture in the container boils, producing a gaseous fraction, necessary for operation of the boiler. Propane evaporates first, and only then turn comes to butane. In the heat absorbed during the process. The balloon begins to freeze. As a result of gas remaining in the cylinder (butane), too cold. This reduces the degree of volatility. Accordingly, the pressure drops required for the operation of the boiler.

Only one way out - not to give the balloon to freeze and warm it up to the positive temperature needed to vaporize butane. For example, can be heated cylinders (not open electric cables!) On the principle of a warm water floor, placing them in a gas-insulated cabinet.

Safety measures when using gas equipment

A mixture of propane-butane is much heavier than air. Liquefied gas from cylinders always accumulate at the bottom. Escaping gas if the cylinder standing in the room, you can smell it just did not feel until they reach explosive concentrations. Therefore, the setting of the container on the street, vertically in an iron box with holes at the bottom and at the top for ventilation.

TB regulations prohibit: place the gas bottles in the cellar, basements, cellars, wells dug in the courtyard or near the house. Besides:

• Do not use heating with gas cylinders, electric heaters, heating cables, heating elements, etc.
• Gas cylinders must be placed in special cabinets installed on the north side of the house.

• The balloon can not be refilled more than 80% of its volume. The liquid gas has a large coefficient of volumetric expansion. This means that as the temperature rises, the gas volume in the vessel increases. The expansion coefficient of propane-butane mixture of about 7%. According to Russian standards is left 15% of the expansion. The container of any thickness and tear strength when fill it with more than 93% in the cold -20 ° C and add to the room where the + 20 ° C.
• All detachable connections for the gas pipe should be checked for leakage obmylivaniem.
• Split compounds are made in different places of attachment elements, wherein the other compounds are not possible (taps, counters, gas appliances and so forth.)

• Pipelines made of steel pipes with a wall thickness of at least 2mm. At passage walls, the tube is placed in a pouch, zapenennuyu soft material. Connecting the appliance to the gas pipeline can be made flexible liner specifically designed for this purpose. Connecting the reducer to the gas pipeline is made of rubber-fabric sleeve (rubber-canvas hose).
• If the balloon is in the room next to the boiler, the connection is made of rubber-fabric sleeve.
