Tips on energy saving

Heating economically

The appliance provides a high level of comfort whilst keeping gas consumption low and so minimising the environmental impact.

The gas supply to the appliance‘s burner is regulated according to the demand for heat. The appliance operates with a low flame if 
the demand for heat reduces. The technical term for this process is modulating control.

Modulating control reduces temperature fluctuations and provides an even distribution of heat throughout the home. This means 
that the appliance may stay on for relatively long periods of time but will use less gas than a appliance that continually switches on 
and off.

Central heating systems with room thermostat/thermostatic radiator valves

With modern heating systems designed around a 20 °C heat loss across the system, the optimum setting for a condensing appliance 
as described on section 3.1.2,Setting the boiler flow temperature for the central heating system. The system must be balanced 
correctly and the radiators may need upgrading. 

The temperature of each room can be set individually (except primary room with the room thermostat) using the thermostatic 
radiator valves.

Room thermostats

Reducing the setting of the room thermostat by 1°C can reduce fuel consumption by up to 10%.

New control systems

Upgrade your heating control system if necessary with the latest equipment available.

Roof insulation

Around 30% of the heat loss from a property is through the roof. Replace any old insulation with new insulation, preferably of around 
200mm thickness or more.

Window frames

Single glazed windows, particularly those with steel frames, can lose a great deal of heat. Consideration should be given to 
replacement with PVCu or wooden framed double glazed units.

Radiators

If a radiator is sited underneath a window, its performance will be affected if the curtains are allowed to drape over the radiator. 
Shelves fitted above or in front of the radiator should also be avoided.

It is advisable to manually adjust all thermostatic radiator valves every 2 - 3 months to prevent them sticking. Ensure radiator valves 
are correctly set and not damaged.

Draughts

Try to ensure that draughts around doors, windows, letter boxes and keyholes etc. are reduced by using a suitable draught excluder. 

Curtains

Lined curtains, or heavier full length curtains can provide excellent insulation. However, always ensure that the curtains do not 
drape over radiators.

WARNING: 

Air vents

▶ Do not block or seal any air vents that are installed to ensure that the central heating appliance operates safely.
