ADDITIONAL HEAT
The additional heat is the heat produced in addition to the heat supplied
by the compressor in your heat pump. Additional heaters can be for ex-
ample, immersion heater, electric heater, solar power system,
gas/oil/pellet/wood burner or district heating.
BUFFER VESSEL
A buffer vessel increases the system volume and removes the unwanted
temperature variations that can otherwise be sent out on the climate
system. This ensure the running of the heat pump and reduces the heat
spikes that could otherwise be heard from the climate system.
CALCULATED FLOW LINE TEMPERATURE
The temperature that the indoor module calculates that the heating
system requires for an optimum accommodation temperature. The colder
the outdoor temperature, the higher the calculated supply temperature.
CHARGE PUMP
See "Circulation pump".
CIRCULATION PUMP
Pump that circulates liquid in a pipe system.
CLIMATE SYSTEM
Climate systems can also be called heating systems. The building is
heated using radiators, under floor coils or convector fans.
COMPRESSOR
Compresses the gas state refrigerant. When the refrigerant is com-
pressed, the pressure and the temperature increase.
