Install the heating. Combined boiler: advantages and disadvantages

When building a new home is always givenattention to two things - quality thermal insulation and heating systems. And if with a choice of heat-insulating material, many do not have special problems, then with the choice of the right boiler everything is just the opposite. Today we would like to talk about the advantages and disadvantages of combined furnaces. We also learn their power and average price.

What is especially this heating?

Combined boiler is a conventional oven,more similar to a wood or gas, in which several energy sources can be used at once. Most often it is gas and diesel fuel. There is also a combined heating boiler "gas + firewood", however it is less popular and in demand on the Russian market. Thus, the main feature of this furnace is its ability to work with several types of energy, which can not boast of either gas or wood analogues.

Application and Benefits

Especially in demand such heating (boilercombined) in suburban cottages and cottages, where often there are interruptions with the supply of gas. And even if the main energy source has ceased to flow into the system, the boiler will quickly switch to autonomous work and will provide the same heat and maintain a constant temperature in the house (of course, if there is diesel or wood). In addition, this heating (combined boiler) is distinguished by its durability and reliability. Such furnaces are much less likely to fail than the same gas.

Power

Unfortunately, universality left itsa negative impact on the performance of this device. Combined boilers, as a rule, have a lower power by 15-20 percent than their full-fledged gas "brethren". In general, the standard performance of such furnaces is about 30-40 kW.

Why does it depend on electricity?

The main drawback of this device is notis less power. The fact is that because of the use of an integrated fuel pump, blower fan and other electrical devices, this tool simply can not do without the supply of a direct current. Therefore, if not only gas but also light is turned off in the house, such a boiler will no longer work. As you can see, this furnace is not 100 percent autonomous,

as, for example, wood. If the current is not delivered for several days, there is a big risk that the water in the system and the batteries will simply freeze. And to restore such heating (combined boiler) is unlikely to be achieved in a few hours, even after the electricity supply resumed.
