COP
If a heat pump has COP of 5, this means that you only pay for a fifth of
your heating demand. This is the efficiency of the heat pump. This is
measured at different measurement values, e.g.: 7 / 45 where 7 stands
for the outdoor temperature and where 45 stands for how many degrees
the supply temperature is maintaining.
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.
DOT, DIMENSIONED OUTDOOR TEMPERATURE
The dimensioned outdoor temperature differs depending on where you
live. The lower the dimensioned outdoor temperature, the lower the
value should be selected on "selecting a heat curve".
EFFICIENCY
A measurement of how effective the heat pump is. The higher the value
is the better it is.
ELECTRICAL ADDITION
This is electricity that, for example, an immersion heater uses as addition
during the coldest days of the year to cover the heating demand that the
heat pump cannot manage.
FILTERING TIME
Indicates the time the average outdoor temperature is calculated on.
FLOW PIPE
The line in which the heated water is transported from the heat pump
out to the house heating system (radiators/heating coils).
