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 the first and second
segment 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.
