Functional principle of the heating system
4. Functional principle of the heating system
Components Function
Gas boiler Burns natural gas safely and in an en-
vironmentally friendly manner. Extracts
the heat from the generated combustion
gases and transfers it to the heating water.
Calorifier It holds a reserve of domestic hot water
for consumption (e.g. for showering).
Boiler control unit Controls and monitors the operation of
the boiler. Maintains the desired room
temperature optimally and fuel-efficiently,
independent of the outside temperature.
Radiator, underfloor heating Releases the heat of the heating water
into the room.
Heating pump Transports the heating water from the
boiler to the radiators and back to the
boiler, where it is reheated.
Mixing valve Adjusts the heating flow temperature by
mixing in colder return water (water flow-
ing to the radiator) to maintain the desired
room temperature, independent of the
outside temperature.
Pressure gauge Displays the hydraulic pressure in the
heating system.
Air vent Eliminates any air to make sure that the
system contains only heating water.
Safety valve Prevents overpressure in the system.
Diaphragm expansion tank Maintains the pressure in the system at a
constant level.
