TIPS ON ENERGY SAVING

HEATING ECONOMICALLY
The boiler provides a high level of comfort whilst keeping gas consumption low and so minimising the environmental impact.
The gas supply to the boiler's burner is regulated according to the demand for heat. The boiler 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 boiler may stay on for relatively long periods of time but will use less gas than a boiler 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 boiler will
be approximately between one and two on the central heating temperature control. 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.
