Central heating
Gas and electric boilers can be set for the heating and/or hot water to switch on at times you choose.
Cold weather #
Do NOT switch heating off between October and April even if you are away from the house. We recommend heating of at least 12°C to prevent burst pipes and condensation.
Night storage heaters #
Night storage heaters are wall or floor-mounted electric powered heaters that look like radiators and set using a switch. They heat up at night on a cheaper off-peak electricity tariffs and release it during the day.
Typically, cheaper off-peak tariff rates are available between:
- 1.30am to 8.30am in the summer
- 12.30am to 7.30am in the winter
but this may vary according to supplier.
Heaters take 24 hours to produce heat. Some offer a boost button or instant fan heater that provide instant heat, but this is charged at the more expensive day rate tariff.
Safety #
Do NOT put cover night storage heaters: it is a fire hazard and could stop the heater working.
Using Economy 7 / storage heaters #
Night storage heater controls vary but each provides a standard set of controls:
Input control dial:
Controls the amount of heat stored in the heater at night. Set this to the mid-point when used for the first time. Adjust it as necessary over the following days.
Output control dial:
Controls the amount of heat given off during the day. Set this to 1 to release heat gradually during the day. You can increase or decrease this as necessary.
Turn the output dial back to 1 before going to bed. This uses all the stored heat and reduces electricity use.
There may be other controls including:
- Timer: control heating and output times.
- Boost: permits extra heating at more expensive daytime peak rates.

Economy 7 water heaters #
Your water is heated by an Economy 7 heater when:
- there are two thermostats and two cables attached to the hot water cylinder at the top and bottom.
- your electricity meter has two sets of dials or numbers showing day and night readings, such as RATE 1 (standard / peak) and RATE 2 (Economy 7 / off-peak).
Remember to switch back to the off-peak rate to avoid high bills.
