5 Energy saving tips
▪ Operating the unit in central heating ECO mode provides the most
economical central heating operation conditions.
▪ Do not run the boiler in domestic hot water comfort mode.
Domestic hot water comfort mode involves pre- and post-heating,
which is luxury, not necessity.
▪ Close the thermostatic radiator valves when ventilating the rooms.
▪ The largest heat loss occurs through windows and outer doors.
Check windows and doors for air-tightness. Close any blinds at
night.
▪ Do not hide radiators behind large furniture (i.e. couch, desk, etc.).
Minimum 50 cm of clearance must remain, otherwise the heated
air cannot be circulated and the room will not heat up efficiently.
▪ Do not let your room become too hot. Decreasing the room
temperature during the day saves energy.
▪ Have your combi boiler's maintenance performed at least
annually.
▪ Provide your building with sufficient heat insulation.
▪ Thermostatic valves should be used. Each room should be
adjusted according to comfort conditions. For reception rooms,
this is 20°C, living rooms 22°C, kitchens 18°C and bedrooms
18°C.
▪ Prevent radiators from getting covered by curtains.
