Heating with gas cylinders in a private house is in demand in those places where it is not possible to connect to the central gas pipeline or there is an unstable supply of electricity for the installation of electrical equipment.
Arrangement of heating in a private house with gas from cylinders
Russia is an incredibly large state with many more settlements located far from the benefits of civilization and main roads. To make life easier, people install a gas boiler from a cylinder.
There are no prohibitions or restrictions on an autonomous gas heating system from bottled gas. But there is a significant drawback - a large amount of fuel is required to heat a room, since it differs from gas from the central highway.
Heating the living space with liquefied gas is advisable in the following cases:
- minimal heat loss;
- building area up to 100 sq. m .;
- effective thermal insulation of the structure.
Heating with bottled gas can be seen as a temporary solution to the problem, since an existing boiler can be retrofitted in the future to be supplied from a central gas pipeline.
Heating of a private house with liquefied gas is carried out using standard cylinders with a capacity of 50 liters.
Heating of premises is carried out by combinations of the following combustible substances:
- SPBTZ - winter version of the mixture;
- SPBTL is a summer option.
In winter, the cylinders require constant monitoring. Even at abnormally low temperatures, gas mixtures do not freeze, but interruptions in their supply to the boiler are possible. To reduce the likelihood of breakdowns, for the winter period it is recommended to organize the heating of the box with pipes according to the principle of a warm floor.
Which boiler to use
Gas heating of country houses from cylinders is carried out using a heat generator for a boiler with a water circuit. You can use any modifications and models of heating boilers that are designed to burn natural gas. For optimal performance, it is sufficient to replace the burner or replace / adjust the nozzles. Many manufacturers include a special kit for liquefied gases in their delivery.
Similarly, the device and its power are selected. However, taking into account the high operating costs for gas cylinder heating, it is necessary to purchase a boiler with a high efficiency, for example, a gas condensing heat generator.
Boiler connection diagram
If cylinders will be installed at home, the system must additionally be equipped with the following parts:
- shut-off valves;
- boiler;
- ramp;
- special nozzles for gas, if they are not included with the boiler;
- reducer.
It is not recommended to install cylinders in basements or basements, the most optimal place for them is a specially made metal box with ventilation holes on top and bottom of the front part.
Full cylinders must be stored strictly in a horizontal position, vertical is unacceptable. Install a metal box on the north side of the building in the most shaded place. For optimal operation of the heat exchanger, you need to connect it to 4-5 heating cylinders.Before connecting them, you first need to familiarize yourself with all the installation features.
To install the outlet gas pipeline, it is necessary to use pipes with a wall thickness of at least 2 mm. A sleeve with a diameter exceeding the pipe diameter by 15-25 mm is mounted in the wall at the place of its passage. The gap between the pipe and the sleeve circumference is filled with polyurethane foam.
The common reducer is connected simultaneously to several cylinders using a ramp - a two-arm manifold that divides them into a main and a spare bundle.
The system can be equipped with gas holders, this is done using a reducer that returns gas from a liquid to a vapor state for its secondary supply to the boiler. However, such an installation will require large financial costs.
During installation, all connections are made using hoses and pipes, their tightness is checked by soaping the joint.
Gearbox characteristics
Cylinder pressure is a variable that depends on a variety of conditions. For example:
- distance from the box with cylinders to the boiler;
- number of cylinders;
- temperature and composition of the gas mixture;
- remaining fuel.
A reducer is a part designed to maintain and convert pressure in a stable state.
Choose a suitable gearbox for two characteristics:
- operating pressure;
- performance.
The energy efficiency of the heating system at home with gas cylinders depends largely on fuel consumption. The efficiency of the reducer should not be less than the boiler injectivity.
The device is selected according to the value of the working pressure in accordance with the parameters of the heater. If the pressure supplied to the reducer is too high, the boiler automation may fail or the burner will simply go out.
Reducers have different modifications, they are produced with pressure parameters of 30, 37, 42 and 50 mbar. There are models in which it is possible to adjust this parameter between 20 and 60 mbar.
When connecting cylinders using flexible hoses, you will need a reducer equipped with a “herringbone” fitting; when connecting with rigid pipes and combs, you will need fittings with threaded outlets.
Automatically switchable gearboxes are equipped with protective elements. If the pressure of the system reaches critical levels, the automation is triggered and opens the relief valve.
House heating consumption with gas cylinders
If the area of the house is about 100 square meters, the boiler power must be at least 10 kW. To obtain 1 kW of heat, about 100-120 g / min of fuel will be required at 100% boiler load. If, for example, the duration of cold weather per year reaches 7 months, approximately 5 tons of liquefied gas will be required for the entire season.
In practice, the flow rate is slightly less, since when the temperature rises, the automation switches the system into an economical mode. If we compare the costs with the main pipeline, they will be approximately 5-6 times higher. But it is much cheaper than heating the room with electricity.
Fuel consumption can be reduced thanks to the following rules:
- install automation;
- purchase fuel from regular and trusted suppliers, the composition of the gas must be excellent;
- mount propane sensors in a room with cylinders, which will allow you to immediately identify leaks;
- be sure to observe the optimal temperature regime.
If you follow these simple guidelines, gas consumption can be reduced by about 20-40%.
solid fuel boiler + electric boiler!
it really helps to save money!
while in the house heat the boiler if you need to go in parallel, turn on the electric boiler!
woke up in the morning threw a full boiler of firewood went to work!
until 12 the firewood smolders after the electric boiler turns on! arrived at 18-20 o'clock again melted solid fuel!
and up to -15, the electric boiler does not even need to turn on the house in a day does not have time to cool down!
You calculate how much money this HEAT will cost ... ... Consumption, a balloon for a day, and this despite the fact that you were filled up normally. That is, a refueling per week is 4300 rubles, plus someone has to carry and refuel all this. there is still a moment of condensation, at low temperatures the balloons freeze dull and there is no transition from a liquid to a gaseous state. And also do not forget that all these systems are volatile, there is no light, there is no heat.
