Functional principle of the heating system
Function:
Burns oil safely without harming the environment.
Extracts the heat generated by burning the oil from
the exhaust gases and transfers it to the heating
water.
The energy in the heating oil is converted into heat
through burning it in the heating boiler.
It holds a reserve of domestic hot water for consump-
tion (e.g. for showering).
Controls and monitors operation of the heating boiler.
Ensures that, whatever the temperature outside, the
room temperature is as required – in an optimum and
fuel-efficient manner.
Delivers the heat from the heating water to the room.
Transports the heating water from the heating boiler
to the radiators and back again to the heating boiler,
where it is reheated.
Convey the heat generated from the heating boiler to
the radiators.
Modifies the feedwater temperature (water being fed
into the radiator) so that irrespective of the outside
temperature the desired room temperature is at-
tained. This is achieved by the addition of a propor-
tion of cooler water from the heating return circuit.
Indicates the water pressure in the heating system.
