With the need to device heating system faces every owner of a private home.It is important that the house was warm and preferably without major upheaval for the family budget.Proper selection of the boiler mostly determines the efficiency of the entire heating system.Simple layman difficult to navigate in the variety of offerings on the market of heating systems.What the buyer sees simple?- Heating boilers for home in different price ranges, varying in capacity, by type of fuel used by the method of fastening and efficiency.You can easily become puzzled.What is the boiler house is better?- Definitely difficult to answer, it all depends on the conditions of use.To the choice of boiler was conscious and prudent, we consider a variety of boilers for private homes more.


power calculation boiler ↑

As we noted above, the boilers for heating private houses of different capacities.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.When using the hot water boiler is planned or floors, 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 m² of floor space required 1 kW of power boiler to the result should be added from 15 to 20% to compensate for the loss of heat.

Selecting the boiler depends on the conditions of use.If the house is supplied with gas, it is advantageous to use a gas boiler.In the absence of gasification boilers can be installed using liquid or solid fuel, is another option - an electric boiler.

Classification by type of fuel consumed ↑

  • gas;
  • solid;
  • power;
  • oil boilers;
  • combi boilers.

consider every kind of detail.

Cheap gas boilers ↑

Gas boilers for private homes using liquefied gas and natural gas.Modern gas-fired boilers for home fully automated, for their work need electricity.Gas boilers are floor, wall, single and dual circuit.Floor boilers desirably set in separate rooms, specially designed chimneys and ventilation channels.For the efficient operation of the heating system with floor boiler needs water pump.

Wall boilers have built-in water pump, combustion chamber of the boiler can be open or closed.In boilers with a combustion chamber in open air chamber enters the room, and the combustion products are discharged natural draft through the chimney.In boilers with a combustion chamber of closed type air supply and flue gas discharge is carried out forcibly by an electric fan.The combustion air is then carried from the street.A disadvantage of gas boilers with open combustion chamber is that in low-powered boiler will not operate.If automation is faulty, there is a high probability of penetration of carbon monoxide in the room.Use a gas boiler for private houses economically.When compared with boilers for solid and liquid fuel, this type of boilers require less attention from the user.Compared to electric, gas boilers is much more profitable for the price of fuel.

Also for central heating gas boiler can perform another function of heating water for hot water supply.These boilers are called double-contour.Single-boiler may only be used to heat your home.

Units for solid fuel ↑

Boilers for solid fuel heating
Solid fuel boilers

for solid fuel boilers diverse: wood, coal, pellets, etc.There are simple and Pyrolysis solid fuel boilers.The main disadvantage of ordinary boilers is the low efficiency and the need for frequent batch of fuel (every 3-4 hours).But solid simple boilers are not dependent on electricity, which can be an advantage in certain circumstances (when the electricity is not available).

gasification boilers on the other hand, are very economical: fuel has carried out only 1-2 times a day.The principle of operation is based on the pyrolysis boiler combustion gases from the dry distillation of fuel.To operate the boiler electricity.The combustion process is controlled by automation.The fuel feed to the pyrolysis boiler can be carried out mechanically, for that purpose the granules (pellets).The disadvantage of the use of pellet boiler is the high cost of pellets.

Practical electrical equipment ↑

Electric boiler to heat your home
wall electric boiler

Electric boilers for home heating is easiest to install.They do not require air 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 boiler 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: special automatic installation allows you to select economy mode power consumption.

Electric boiler can be a worthy substitute for gas: a boiler easy installation and operation, compact and environmentally friendly.It can be installed in any room.But for heating an area of ​​over 50 m² require special wiring that can withstand heavy loads.And the cost of electricity is somewhat higher cost of gas.

Universal oil boilers ↑

Boiler on liquid fuel

Typically, for liquid fuel boilers used diesel fuel.Store the fuel near the home is unsafe, and the cost of diesel fuel is quite high, so it is impossible to name the preferred option.Is that the gas and solid fuels are not available.However, there is an obvious advantage - the ease of switching 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 profitable use if soon expected gasification section.To install the boiler consuming liquid fuels require a separate room with exhaust ventilation.Be sure to observe the temperature.Fuel oil boilers are sensitive to changes in fuel composition.Without a filter to clean the fuel quickly clogged fuel injectors.

Universal boiler for home heating is not dependent 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 kind of boiler you choose, remember that the installation of the boiler in a private house have to be made by qualified personnel only.It is important to consider all the technical standards and safety regulations.
