Boilers for heating private houses
With the necessity of heating devicesfacing each owner of a private house. It is important that the house was warm and, preferably, without great upheaval for the family budget. Proper selection of the boiler mostly determines the efficiency of the entire heating system. An ordinary man in the street is difficult to navigate in the variety of offerings on the market of heating systems. What the buyer sees simple? - Heating boilers for home different price categories, varying in capacity, by type of fuel used, by way of fasteners and efficiency. Can easily become puzzled. Which house is better boiler? - Definitely difficult to answer, it depends on the conditions of use. To the choice of boiler was a conscious and balanced, consider the various boilers for private homes more.

Calculation of power boiler
As we noted above, for boilers heating private house differ in power. Calculation of the thermal capacity of the boiler is made of the future taking into account the volume of the heated space, the nature of home insulation and climatic conditions of the winter period. If the boiler is planned using heated water or the floor, the calculations also important to consider the additional load. Calculation of power is better to entrust Heating engineer. As an approximate calculation can result in the following recommendations: for every 10 m? floor space required 1 kW of power boiler to the result should be added from 15 to 20% to compensate for the possible loss of heat.
Choosing the boiler depends on the conditionsuse. If the house is supplied with gas, it is advantageous to use a gas boiler. In the absence of gasification boilers can be installed running on either liquid or solid fuel, is another option - an electric boiler.
Classification by type of fuel consumed
- oil boilers;
- combi boilers.
Let us consider each type in more detail.
Cheap gas boilers
Gas boilers for private homes using liquefied ornatural gas. Modern gas-fired boilers for home fully automated, for their work need electricity. Gas boilers are floor, wall, single and double-circuit. Floor boilers desirably set in separate rooms, specially designed chimneys and ventilation channels. For efficient operation of the boiler with a floor heating system is needed water pump.
Wall-mounted boilers have built-in water pump,the combustion chamber of the boiler can be open or closed. In boilers with open combustion chamber type air in the chamber enters the room, and the products of combustion are discharged natural draft through the chimney. In boilers with a combustion chamber closed-type air supply and flue gas discharge is carried out forcibly by an electric fan. The air intake is thus carried out in the street. The disadvantage of gas boilers with open combustion chamber is that when there is insufficient traction boiler will not work. If the equipment is faulty, there is a high probability of penetration of carbon monoxide in the room. Use a gas boiler is economically profitable for a private home. When compared to boilers running on solid or liquid fuel, this type of boilers require less attention from the user. If we compare with the electric, gas boilers are much more profitable for the price of fuel.
In addition to space heating gas boiler canperform another function of heating water for hot water supply. These boilers are called double-contour. Single-boilers may only be used for heating homes.
Units for solid fuels
Fuel solid fuel boilers diverse: wood, coal, pellets, etc. There are simple and Pyrolysis solid fuel boilers. The main disadvantage of ordinary boilers is low efficiency and the need for frequent batch of fuel (every 3-4 hours). But simple solid boilers are not dependent on electricity, which can be an advantage in certain circumstances (when electricity is not available).
pyrolysis boilers on the contrary, it is very economical: fuel tab is carried out only 1-2 times a day. The principle of pyrolysis boiler is based on the combustion of gases produced by the dry distillation of fuel. To operate the boiler electricity. The combustion process is controlled by automation. Fuel supply to the pyrolysis boiler can be carried out mechanically, specific granules (pellets) used for this purpose. The disadvantage of the use of pellet boiler is the high cost of pellets.
Practical electrical equipment
Electric boilers for heating houses setthe easiest way. They do not require ventilation ducts and chimneys. Electric boilers are compact, they can be easily installed on a wall, in addition, they are silent, environmentally friendly and safe. The disadvantage of installing an electric boiler is a need for electrical wiring capable of withstanding heavy loads. In which case, do not use an electric kettle to heat your home? - If power outages are not uncommon in your area. Despite the relatively low cost of electric boilers, do not forget about the relatively high cost of electricity. However, you can always save you: setting a special automation allows you to select an economical power consumption mode.
Electric boiler can be a worthy substitutegas: this boiler is simple installation and operation, compact and environmentally friendly. It can be installed in any room. But for the heating area of more than 50 m? It requires special wiring that can withstand heavy loads. And the cost of electricity is somewhat higher cost of gas.
Universal oil boilers
Typically, for liquid-fuel boilersused diesel fuel. Store fuel closer to home is not safe, and diesel fuel cost is quite high, so you can not call this option preferred. Is that the gas and solid fuels are not available. However, there is a clear advantage - the ease of conversion to another type of fuel: it is necessary only to replace the burner and liquid fuel boiler will operate as a gas. These boilers are called "universal".
Universal heating boilers residential building profitableuse if soon expected gasification section. To install the boiler fuel oil consuming need a separate room with exhaust ventilation. Pay attention to the temperature regime. Fuel oil boilers are sensitive to changes in fuel composition. Without a special filter for the fuel clearing quickly clog the fuel injectors.
for home heating boiler is not universaldependent on external sources of energy (such as electricity or natural gas), so it can be installed to create a back-up heating in case of power failures or low gas pressure in the pipeline.
Whatever type of boiler you choose, you mustkeep in mind that the installation of the boiler in a private home must necessarily be carried out by qualified personnel only. It is important to consider all the technical standards and safety regulations.
