Combined heating furnaces operate on several types of energy. The most advanced models use up to 4 types. Due to their complete autonomy, combined heating furnaces are also called universal.
Pros and cons of combined heating boilers
Pluses of combined boilers for heating a house:
- Any kind of energy carrier will do;
- You can change fuel in a matter of minutes;
- You can mount a boiler;
- Are compact;
- High efficiency;
- The boilers operate in automatic mode, the owner does not need to monitor the process;
- It is possible to connect a warm floor and batteries at the same time.
Cons of combined boilers for heating a house:
- The boiler is quite expensive;
- It is necessary to equip a storage facility for solid and liquid fuels;
- Their power is not more than 35 kW.
The principle of operation of combined boilers
All combined heating boilers They are divided into two types: double-circuit and single-circuit. The second can only supply water to the heating system. The former provide hot water for domestic use.
All combined gas-electricity boilers are installed on the floor, as they are very heavy. When installing a combined heating gas gas boiler, automatic control is mandatory. It makes the operation of the equipment safe and efficient.
Boilers can be with one firebox or two. The second option is more convenient, where you do not need to manually change the burner (for example, diesel to gas).
Boilers firewood electricity
Combined heating wood heating boilers electricity is produced with a single firebox in which firewood is placed. And the tank for heating water is located above the firebox. Very important in the design and the chimney, passed through a water tank. Some models of combined boilers for heating wood and electricity are equipped with a heat chamber that increases the efficiency of the boiler. It is located above the water tank, and the chimney is diverted from it. Electrotenes are mounted in the tank.
Gas firewood boilers
They can be with one or two fire chambers located one above the other. The chimney is mounted above the upper chamber of the furnace, and the gas burner is at the bottom. Due to this design of combined heating boilers, gas firewood is heated simultaneously both combustion chambers. However, its minus is that the ash from burnt firewood falls into the lower chamber, where it needs to be removed. Many models are equipped with an ash tray. The pallet can be pulled out and if the combined heating boiler gas firewood only works on gas, it is not used.
