Protecting your heat
Heating your home during the colder months uses a large amount
of the energy you use throughout the year. Ensuring your heating system is
running efficiently and that you are not wasting any energy can therefore
help you to make big savings on your fuel bills.
Easy ways to save energy
• Try to wash a full load in your washing machine - for smaller wash
loads use a half load programme if available on your machine.
• Don’t overheat your hot water either – 60 C is the optimum setting for
your cylinder thermostat.
• It may sound obvious, but if you are too warm, turn the heating down
to reduce the temperature rather than opening windows.

3. • Have radiators fitted with thermostatic controls to regulate heat in
each room.
• Have your boiler regularly serviced – this will increase its energy
efficiency.
Make Your Boiler More Energy Efficient
If your boiler is more than ten years old, it’s probably far less
efficient than modern models. Replacing an old boiler with a new high-
efficiency condensing boiler can save you around a third on your heating
bills straight away.* And if everyone in the UK with gas central heating
switched to a high-efficiency condensing boiler, we would save enough
energy to heat 3.7 million homes for a year.
Replacing an old gas boiler with A-rated high efficiency
condensing boiler and improving your heating controls could save you as
much as £300 a year on your energy bills.*

current one regularly and professionally serviced will considerably
improve its efficiency.

Make Your Central Heating More Energy Efficient
Heating controls give you more scope to ensure your home is
heated as you want it – ensuring the rooms you use are warm and those
you don’t aren’t being heated unnecessarily.

5. If your central heating system uses radiators (i.e. a ‘wet’ system), the
ideal controls to have are:
A room thermostat – this allows you to set your preferred
temperature, typically between 18 C – 21 C. As soon as the room reaches
that temperature, the thermostat will switch off the hot water supply to
radiators, then when the temperature drops it will turn back on again.
Ideally, your thermostat should be fitted at eye-level on the wall of a room
you use most (e.g. the living room) and not in a direct draft or by a head
source (e.g. over a radiator or a cooker).
A programmer – this controls when your heating and hot water
come on and go off, so you only have them on when needed. If you are
unsure how to set your programmer, contact us for advice.

6. A cylinder thermostat (if you have a hot water tank) – this
controls the temperature of hot water leaving the hot water storage
tank. The thermostat is usually fitted to the tank itself, with the
temperature sensor at the back, in contact with the cylinder inside.
Your thermostat should be set to no more than 60 C. Any higher, and
your energy bills could increase.
Thermostatic radiator valves (TRVs) – these allow you to
control the temperature in each room, automatically turning off the
flow of hot water to the radiator when your required temperature is
reached. For example, you might use a minimum setting in unused
bedrooms to keep damp and condensation at bay, while the rooms you
use daily are set to a warmer temperature.
A plumber can fit any of these controls for you.
