TIPS ON ENERGY
SAVING
Heating economically
The boiler is designed to provide a high
level of comfort while keeping gas con-
sumption and the resulting environmen-
tal effect as low as possible. The gas
supply to the burner is controlled accor-
ding to the level of demand for heat.
The boiler continues to operate with a
low flame if the demand for heat redu-
ces. The technical term for this process
is modulating control. Modulating con-
trol reduces temperature fluctuations
and provides even distribution of heat
throughout the home. This means that
the boiler may stay on for relatively long
periods but will use less gas than an
appliance that continually switches on
and off.
TIPS ON ENERGY SAVING
Central heating systems with room
thermostats/thermostatic radiator
valves
The central heating control on the boiler
should be set to the maximum rated tem-
perature of the central heating system.
The temperature of each room can be
set individually (except primary room with
the room thermostat) using the thermo-
static radiator valves.
Roof insulation
Around 30% of the heat loss from a pro-
perty is through the roof. Replace any
old insulation with new insulation, prefe-
rably of around 200 mm 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 woo-
den framed double glazed units.
Curtains
Lined curtains, or heavier full length cur-
tains can provide excellent insulation.
However, always ensure that the curtains
do not drape over radiators.
