Should I turn off the boiler and water-heating in summer?

Read on to find out if turning off your boiler for the summer is a good idea.

Is turning off the boiler the right choice?

If you have an old boiler — especially one with a continuously burning pilot light — it may well be worth turning off the boiler in the months when it's not used for heating the home.

Even if you have a more modern boiler, you may want to switch it off if the water cistern is not a modern one coated with polystyrene.

If you have an electric shower — and don't take baths during the summer — and a dishwasher, only water used at the kitchen sink and in a bathroom hand-basin would need to be heated.

Old washing machines and dishwashers with hot fill — where the machine uses water heated by your boiler — are still able to heat up cold water to the appropriate temperature for internal use, and modern machines which are cold fill only will not need any external hot water.

However, it's always best to run your central heating and hot water occasionally during the summer.

If this happens, they could fail when you finally turn the heating back on in the autumn.
