4. Functional principle of the heating system
Component Function
Gas heating boiler Burns natural gas safely without harming
the environment. Extracts the heat gene-
rated by burning the oil from the exhaust
gases and transfers it to the heating wa-
ter.
Water heater It holds a reserve of domestic hot water
for consumption (e.g. for showering).
Boiler control Controls and monitors operation of the
heating boiler. Ensures that, whatever the
temperature outside, the room tempera-
ture is as required – in an optimum and
fuel-efficient manner
.
Radiators, underfloor heating Delivers the heat from the heating water
to the room.
Heating pump Transports the heating water from the he-
ating boiler to the radiators (for instance to
the heating boiler, where it is reheated.
Mixer valve Alters the heating flow temperature
through addition of colder heating return
flow water (water flowing to heating ele-
ment/radiator) so that the required room
temperature can be maintained for any
given outside temperature.
Manometer Indicates the water pressure in the heating
system.
Vent Ensures that only heating water (i.e. no
air) is contained in the plant or radiators.
Safety valve Prevents pressure in the system beco-
ming excessive.
Membrane expansion vessel Keeps the pressure in the system
constant.
