Saving tips
Your 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.
Also remember:
• Open the thermostat valves completely (except in rooms where you
want it to be cooler). The thermostats slow the flow in the heating
system, which VVM 225 wants to compensate by increasing the
temperature. It will then work harder and consume more energy.
• You can lower the temperature when away from the house by
scheduling "holiday setting" in menu 4.7. See
for instructions.
• You can influence the energy consumption by connecting the electric
boiler/indoor module to various additional heat sources, such as solar
or heat pump.
