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, gas/oil/pellet/wood burner or
district heating.
Calculated flow line temperature
The temperature that the heat pump calculates that the heating system
requires for an optimum accommodation temperature. The colder the
outdoor temperature, the higher the calculated supply temperature.
Circulation pump
Pump that circulates liquid in a pipe system.
Climate system
The climate system can also be called the heating and/or cooling system.
The building is cooled or heated using radiators, under floor coils or con-
vector fans.
Compressor
Compresses the gas state refrigerant. When the refrigerant is compressed,
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.
Disturbances in comfort
Disturbances in comfort are undesirable changes to the hot water/indoor
comfort, for example when the temperature of the hot water is too low
or if the indoor temperature is not at the desired level.
A malfunction in the heat pump can sometimes be noticed in the form of
a disturbance in comfort.
In most cases, the heat pump notes operational interference and indicates
this with alarms and shows instructions in the display.
Domestic hot water
The water one showers in for example.
