SAVING TIPS
Your heat pump installation produces heat and hot water. This occurs
via the control settings you made.
Factors that affect the energy consumption are, for example, indoor
temperature, hot water consumption, the insulation level of the house
and whether the house has many large window surfaces. The position
of the house, e.g. wind exposure is also an affecting factor.
Even the house ventilation affects the energy consumption. It is therefore
important to perform a ventilation adjustment shortly after installing the
heat pump. When adjusting ventilation, a ventilation technician sets the
house ventilation device, outdoor air damper and the fan in F730 accord-
ing to the projected values of the house.
Also remember:
• During the adjustment period (winter time) all thermostat valves should
be fully open. The heat pump's heating settings are then adjusted so
that the correct indoor temperature is obtained, in most rooms, regard-
less of the outdoor temperature. In rooms where a lower temperature
is required, the thermostat valves are lowered to the desired level.
After a few months, the remaining thermostats can be lowered slightly
to avoid an increase of the room temperature due to solar radiation,
stove heat etc. Further reductions may be required later on.
• You can lower the temperature when away from the house by
scheduling "holiday setting" in menu 4.7. See page 66 for instructions.
• If you activate "Hot water Economy", less energy is used.
Power consumption
Increasing the indoor temperature one degree increases the energy
consumption by approx. 5%.
Domestic electricity
In the past it has been calculated that an average Swedish household
has an approximate annual consumption of 5000 kWh domestic electri-
city/year. In today's society it is usually between 6000-12000 kWh/year.
