TIPS ON ENERGY SAVING
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.
Curtains
Lined curtains, or heavier full length curtains
can provide excellent insulation. However,
always ensure that the curtains do not drape
over radiators.
Draughts
Try to ensure that draughts around doors,
windows, letterboxes and keyholes etc., are
reduced by using a suitable draught excluder.
Warning - do not block or seal any air vents that
are installed to ensure the central heating boiler
operates safely.
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 with the
latest equipment available. The minimum level of
control for a combi boiler or fully pumped
system is a programmer, interlocking room
thermostat and thermostatic radiator valves.
