• The boiler must be serviced and cleaned at least once per year by a qualified professional.
The annual servicing must be carried out in accordance with the decree of 15
th

annual servicing of boilers whose nominal power is between 4 and 400 kW.
The professional must deliver a certificate to the end user.
• Sweep out at least once per year, or more depending on current regulations.
• All the maintenance operations must be carried out by a qualified professional.
• We recommend subscribing to a servicing contract.
• Only original spare parts must be used.
• Do not clean the casing with abrasive and/or easily-flammable products (e.g. petrol, alcohol, etc.). Always
disconnect the unit's electrical power supply before cleaning it.

15.1 Energy saving
Tips to save energy
• Fully ventilate the room where the boiler is installed.
• Do not block the air vents.
• Do not cover the radiators. Do not position curtains in front of the radiators.
• Put reflective panels behind the radiators to avoid heat loss.
• Insulate the pipes in rooms which are not heated (cellars and attics).
• Close the radiators in rooms which are not used.
• Do not let hot (and cold) water run unnecessarily.
• Install an economical shower head to save up to 40% energy.
• Take showers rather than baths. A bath consumes twice as much energy.
15.2 Atmosphere thermostats and settings
There are different types of atmosphere thermostat. The type of thermostat used and the parameter selected have an
impact on total energy consumption.
• A modulating regulator, potentially combined with thermostat taps, saves energy and offers excellent comfort levels. This
combination enables the temperature to be adjusted separately in each room. However, do not install thermostat radiator
taps in the room where the atmosphere thermostat is located.
• Opening or closing fully the thermostat radiator taps causes undesired variations in temperature. Consequently, these
taps must be opened/closed gradually.
• Set the atmosphere thermostat to a temperature of around 20°C to reduce heating costs and energy consumption.
• Lower the thermostat to around 16°C at night or when you are away. This enables you to reduce heating costs and energy
consumption.
• Lower the thermostat before airing out the rooms.
• Set the water temperature to a lower level in summer than in winter (for example, 60°C and 80°C respectively) when an
on/off thermostat is used.
• When clock thermostats and programmable thermostats need to be set, do not forget to take account of holidays and
days when there is no-one at home.
