Which boiler to choose for heating the house 100 square meters?

Your own private house is a dream for many. And even if you are not engaged in construction on your own, and you are acquiring a ready-made building, there are still a lot of questions regarding its arrangement. First of all, to ensure comfort and coziness, it is not so much the design and interior filling of rooms that is important, as the ability to enjoy the benefits of civilization at any time - water, electricity, heat. And it is desirable to still save money, in which individual line layout will help, and not connect to centralized systems. In this article, we will figure out which boiler to choose for heating the house 100 square meters, since often this kind of area is enough for a comfortable stay of the average family.

Which boiler do you need?

To organize the heating of a house of 100 squares, quite inexpensive compact boiler with a capacity of 10-12 kW is enough. The reasons for this are as follows:

• The area of ​​100 square meters is clearly not enough to accommodate a spacious boiler room with a large boiler. You need a small design that can be placed in a small room, in the kitchen or under the stairs.
• Budget options have low requirements for fuel quality. However, too cheap option can not be chosen, because their energy efficiency is low. The boiler is wasting fuel, which leads to unnecessary costs. You save on purchasing equipment, but the fuel will soon "eat" all your savings.
• Power 10-12 kW is dictated by the considerations that the heat loss of a house of this area is from 10 to 12 kW.

Calculation of heat losses at home

This calculation is quite simple. As practice shows, the amount of heat loss per square of the area is 0.1 kW.So - the value of heat losses for a house of 100 "squares" is: 0.1 x 100 = 10 kW.

If we multiply this figure by 20% in the case of strong colds, we get: 10 x 1.2 = 12 kW.

That's all the calculations.

Gas or Solid Fuel Boiler?

The most effective is a gas-fired boiler. Further on the effectiveness are devices on solid fuel and electricity. This rating is based on the following principle: the sum of costs for obtaining 1 kW of power:

• If you have chosen a budget design, then the gas version is characterized by the lowest operating costs. For a season you burn about 1200-1500 cubes of gas.
• Solid fuel boilers are more expensive compared to gas ones: about 4 cubic meters of firewood and 5 tons of coal during the heating season.
• Electrical design is much less economical: if you have purchased an electrical design, then be prepared for the costs of hundreds of kilowatts per month.

Important! However, the gas boiler also has a worthy competitor - a pyrolysis type boiler that decomposes solid fuel into combustible gases. But the operation of such a boiler is associated with the cost of electricity, and this construction is quite expensive.

Overview of popular home heating boilers in 100 m2

These boilers, according to customer feedback, are the best in terms of price, quality and energy efficiency.

Gas

Consider which boiler to choose for heating the house 100 square meters, if you preferred a gas model.

AOGV 11,6:

• The maximum thermal power is 11.6 kW.
• The size of the heated area is up to 100 m2.
• Number of circuits - 2( can be used for heating and heating water).
• Capacity of the boiler, liters per minute - 2.5.
• The installation site is on the floor.
• Type of fuel: Gas.
• Dimensions 0,9х0,4х0,45 m.

Protherm Panther 12 KTO:

• The heat output is 11.6 kW.
• The maximum area of ​​the heated room is 120 m2.
• Fuel: natural gas.
• Number of circuits - 1( heating).
• Installation location - wall mounted.
• Dimensions - 0,7х0,32х0,32 m.

Solid

Now we'll figure out which solid fuel boiler to choose for a house of 100 sq m.

Cozy-10:

• Thermal power - 10 kW.
• Efficiency 0,72
• Dimensions 0,62х0,48х0,67 m.
• Water jacket capacity - 22 liters.

Burzhuy-K STANDARD-10:

• Thermal power - 10 kW.
• Efficiency - 0,85.
• Dimensions - 0,85х0,38х0,93 m.
• Water jacket capacity - 18 liters.

Stopuva S10U:

• Thermal power - 10 kW.
• Efficiency - 0,87.
• Duration of burning of 1 bookmark( when using coal fuel) - 130 h.
• Dimensions( height, diameter) - 1,92х0,45 m.
• Water jacket capacity - 34 liters.

Electric

As already mentioned, the purchase of an electric boiler is associated with significant energy costs. Consider the two most economical options, if you need to choose a boiler for heating the house 100 square meters.m.

Bosch Tronic 5000 H:

• Thermal power - 13,9 kW.
• Power consumption - 14,1 kW.
• Efficiency - 0,99.
• Number of phases, voltage - 3, 380 V.
• Dimensions - 0,7х0,55х0,27 m.

Kospel EKCO.L1z:

• Thermal power - 12,0 kW.
• Power consumption - 12,5 kW.
• Efficiency - 0,99.
• Number of phases, voltage - 3, 380 V.
• Dimensions - 0,66х0,38х0,16 m.

Important! Electric boilers are compact, but before deciding which boiler to choose for a house 100 square meters.m, it is necessary to really estimate energy costs. The power consumption of 12-14 kW is not affordable for everyone.

Heating pipes

In modern heating systems of private houses, polypropylene pipes are most often used. This material replaced steel and metal plastic.

The advantages of polypropylene are:

• Reliability and durability of joints( by soldering).
• Long working life.
• Ability to withstand high pressures and temperatures.

Important! VALTEC pipes proved to be very good. This is an ideal ratio of affordable price and high reliability.

Choosing the right coolant for

The best option for the coolant is Thermagent -30 EKO propylene glycol antifreeze. This is a good alternative to water. The main advantage of antifreeze is its resistance to high temperatures.

There is also a nuance:

• If for some reason the heating system stops for a while, the antifreeze in the pipes will not freeze. This will avoid the destruction of pipes and damage to sanitary ware.
• If you replace the antifreeze with water, then when the heating system stops, the water in the pipes will freeze for several hours.

In addition, the antifreeze protects the pipes from corrosion and scale.

Important!"Thermal agent ECO" does not corrode rubber and plastic parts. Antifreeze is absolutely harmless for pets and people.

Combustion products outlet

A classic option for removing gases from combustion is natural draft or exhaust through the chimney.

The modern version is a coaxial exhaust, arranged on the principle of "pipe in the pipe."Such an exhaust gas removal system does not require the installation of a conventional chimney. Combustion products are discharged outside the inner tube. Enriched with oxygen, fresh air passes through the gap between the outer and inner tubes.

Important! The effectiveness of such a system does not depend on weather conditions.

Backup boiler

Considering different options, which boiler to choose for heating the house 100 square meters, you need to think about the feasibility of installing a backup unit.

Important! This option should be considered if you chose the solid fuel equipment. The burning time of one fuel bookmark for the overwhelming number of solid fuel boilers is from 3 to 7 hours. All this causes certain difficulties. For example, if you need to leave for a while, there is no one to heat the boiler, and the house will cool down very much.

The solution of the problem is the installation of a backup electric boiler. To avoid significant energy costs, you can use a backup boiler for your time of absence only to maintain the minimum temperature in the premises of the house( so it does not freeze).This mode of operation of the boiler will be the most economical.

The choice of this or that variant of heating a private house is a question of the owner. But you need to consider a variety of factors. Buying a high-tech unit is tempting, but there may be problems with repairs. According to experts, the best option is to install units that operate on different types of fuel.
