Function

Functional description of the heating system

It is important that the perfectly coordinated individual components function properly at all times to ensure 
that your home stays warm in winter. 

FUNCTION:

Burns the wood safely and environmentally friendly. 
Extracts  the  heat  from  the  combustion  gases  and 
transfers it to the heating water.

The wood is combusted within the heating boiler to 
release  and  convert  the  natural  energy  contained 
therein into heat.

It is used as an intermediate storage of hot heating 
water (max. 90ºC). It compensates any differences 
between heat generation and demand.

It holds a reserve of domestic hot water for consump-
tion (e.g. for showering).

Controls and monitors the operation of the heating 
boiler.

Adjusts the room temperature optimally and fuel effi-
ciently, independently of the outdoor temperature.

Releases  the  heat  of  the  heating  water  into  the 
room.

Transports the heating water from the heating boiler to 
the radiators and back into the heating boiler, where 
it is reheated.

Transport the generated heat from the heating boiler 
to the radiators.
