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.
CALCULATED FLOW LINE TEMPERATURE
The temperature that the electric boiler/indoor module calculates that
the heating system requires for an optimum building temperature. The
colder the outdoor temperature, the higher the calculated supply temper-
ature.
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.
CONDENSER
Heat exchanger where the hot gas state refrigerant condenses (cooled
and becomes a liquid) and releases heat energy to the house heating
and hot water systems.
