Home energy use is responsible for more than ¼ of the total UK carbon emissions
which contribute to climate change. Heating and hot water systems based on
boilers account for of this ﬁgure, so it is important to understand how your
controls can help to maximize energy efﬁciency while maintaining your comfort.
Your Timer should be used in conjunction with appropriate temperature controls. In
order to save energy the following general points should be observed:
1. Ensure your system contains a room thermostat (where appropriate) and a hot
water thermostat, and that it is set to an appropriate temperature level, typically
2. Programme your heating (and hot water) to be off when you are not in the
house. If you are concerned about possible frost damage to any exposed pipe
work, it is advisable to ﬁt a frost protection system – your installer can advise
you about this.
3. Think about how you use your domestic hot water – if you have a storage
system, it is not necessary to have this switched on all the time, even when you
are in the house.
4. Consider the heat up times required for your central heating. Every home
responds differently when the heating is switched on. Adjust the start time so
that you are not cold when you get up in the morning. A shorter heat up time is
required for other heating periods.
5. In the evening, when the house is up to temperature, it is often possible to
switch off the heating up to an hour before you go to bed, without any noticeable
reduction in comfort.

WHAT IS A PROGRAMMER?
...an Explanation for Householders (as recommended by the Energy Savings Trust)
Programmers allow you to set ‘On’ and ‘Off’ time periods. Some models switch the central heating and
domestic hot water on and off at the same time, while others allow the domestic hot water and heating
to come on and go off at different times. Set the ‘On’ and ‘Off’ time periods to suit your own lifestyle. On
some programmers you must also set whether you want the heating and hot water to run continuously,
run under the chosen ‘On’ and ‘Off’ heating periods, or be permanently
off. The time on the programmer must be correct. Some types have to be
adjusted in spring and autumn at the changes between Greenwich Mean
Time and British Summer Time. You may be able to temporarily adjust the
heating programme, for example, ‘Override’, ‘Advance’, or ‘Boost’. These
are explained in the manufacturer’s instructions. The heating will not work
if the room thermostat has switched the heating off. And, if you have a hot-
water cylinder, the water heating will not work if the cylinder thermostat
detects that the hot water has reached the correct temperature.
WHAT IS A CYLINDER THERMOSTAT?
...an explanation for Householders (as recommended by the Energy Savings Trust)
A cylinder thermostat switches on and off the heat supply from the boiler to the hot water cylinder.
It works by sensing the temperature of the water inside the cylinder, switching on the water heating
when the temperature falls below the thermostat setting, and switching it off once this set temperature
has been reached.
Turning a cylinder thermostat to a higher setting will not make the water heat up any faster. How quickly
the water heats up depends on the design of the heating system, for example, the size of boiler and
the heat exchanger inside the cylinder.
The water heating will not work if a time-switch or programmer has switched it off. And the cylinder
thermostat will not always switch the boiler off, because the boiler sometimes needs to heat the
Cylinder thermostats are usually ﬁtted between one quarter and one third of the way up the cylinder.
The cylinder thermostat will have a temperature scale marked on it, and it should be set at between
60C and 65C, then left to do its job. This temperature is high enough to kill off harmful bacteria in the
water, but raising the temperature of the stored hot water any higher will result in wasted energy and
increase the risk of scalding.
