TIPS ON ENERGY SAVING
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 heating system is a programmer, interlocking room thermostat and thermostatic radiator valves.
Radiators:
More often than not radiators will be sited underneath a window, so the warm air from the radiator
heats the colder incoming air from the window.
The performance of the radiator will be affected if the curtains are allowed to drape over the radiator or
shelves are fitted above it.
The positioning of furniture and tables in front of the radiator should also be avoided.
It is advisable to manually adjust all radiator valves every 2-3 months to prevent them from sticking. It is
also important that the plastic tops of all valves are always in position and not cracked or damaged to
help prevent accidents. Care should be taken when vacuum cleaning carpets to avoid damage to
valves and pipework.
The heating system and the outputs of the radiators have been carefully selected by your installer. The
temperature obtainable in any given room is dependent on all radiators being operated at the same
time. If you decide to turn off radiators in unused rooms, spare bedrooms etc., you may experience
slightly lower room temperatures in rooms adjacent to unheated rooms.
Heating economically:
The boiler is designed to provide a high level of comfort while keeping oil consumption and the
resulting environmental effect as low as possible.
The central heating control on the boiler should be set as low as possible while still maintaining a
comfortable room temperature.
The temperature of each room can be set individually using the thermostatic radiator valves (except the
primary room with the room thermostat).
Roof insulation:
Around 30% of the heat loss from a property is through the roof. Replace any old insulation with new
insulation, preferably to a minimum thickness of 200mm.
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 (or other appliance) operate safely.
