Now almost every country houseis equipped with an autonomous heating system. And it does not matter whether giving this or a multi-storey cottage, the principle of operation and the arrangement of boilers installed in these rooms, remains unchanged. However, recently many owners prefer not to classical gas, but to combined heaters. Their main advantage lies in the fact that in the absence of a single source of energy, they are quite capable of supplying heat and heating water to another. One of the varieties of these appliances are heating boilers combined "firewood + electricity." We'll talk about them today.
As is known, combined heaters havethe possibility of working with two sources of energy. Most often, it is wood and gas (in some cases, oil refining products). However, in addition, there are heating boilers combined "firewood + electricity". They in the absence of coal and gas can function normally from electrical energy. Thus, the combined heating boilers "firewood + electricity" can work both on solid fuel (chopped wood, coal, pellets or chips), and from an alternating voltage system 220-240 V.
Why such devices have a great demand forthe Russian market? The answer is very simple. The fact is that not every suburban village is currently connected to a centralized gas supply system. Therefore, the only way out in this situation is to install solid fuel or electric heating systems.
In fact, combined heating boilerselectric and wood are different from their traditional counterparts only by the presence of an additional built-in heating element, that is, a tubular electric heater. This element is installed in the heat exchanger tank of the heater.
As for the remaining details of the design,Combined boilers have a rather primitive design, more similar to simple wood analogues. In the lower part of the boiler there is a special furnace, where periodically chopped wood or pellets are loaded. In addition, heating boilers combined "firewood + electricity" have the ability to convert energy into heat because of the combustion of peat, coal or wood shavings.
The algorithm of this boiler is quite simple, likeand its construction. If we consider how heating boilers combine "firewood + electricity" with electricity, then the main heating mechanism will be a tubular electric heater (TEN), which, when absorbing electric current, heats a special spiral. And it in turn transfers heat to the liquid in the heat exchanger. Thus, hot water under the action of the circulation pump enters the heating system and goes along the upper and lower contours along a closed circle.
If it is firewood, then the flame from them heats the heat exchanger with liquid, and it, as in the first case, circulates around the heating system.
