Components
Function
Gas heating boiler
Burns natural gas safely and environmen-
tally friendly. Extracts the heat from the ge-
nerated 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
heating boiler. Maintains the desired room
temperature optimally and fuel efficiently,
independently of the outside temperature.
Radiator, floor heating
Releases the heat of the heating water
into the room.
Heating pump
Transports the heating water from the
heating boiler to the radiators and back to
the heating boiler, where it is reheated.
Mixing valve
Adjusts the heating flow temperature
by admixing colder return water (water
flowing to the radiator) to maintain the
desired room temperature, independently
of the outside temperature.
Pressure gauge
Displays the hydraulic pressure in the
heating system.
Air bleeder
Eliminates any air to make sure that the
system contains only heating water.
Safety valve
Prevents an overpressure in the system.
Diaphragm expansion tank
Maintains the pressure in the system con-
stant.
