Should You Turn Your Boiler Off During Summer?

It’s the ideal time to save money on heating expenses when the sun is shining and the weather is pleasant.

Should you, however, switch off your boiler?

What you use it for will determine the response. While turning off the heat is a smart method to conserve energy, your boiler may be required to heat water for your house. So, before you switch your heater off for the summer, there are a few things to consider.


Turning Off Your Boiler During Summer

The greatest time to switch off your boiler is during the summer.

You won’t need the heating as often (although anything may happen in a British summer), and you’ll be able to save money.

However, if your boiler is turned off for an extended period of time, it might cause complications. The reason for this is because when valves and pumps aren’t operating, they might seize up.

If you do decide to turn off your boiler for the summer, put it back on for a few weeks every few weeks for a brief period of time. This will ensure that it is in the best possible shape when winter returns.


Is it possible to switch off a combi?

While you may not need heating throughout the summer, you will almost certainly want hot water.

If you have a combi boiler, don’t switch it off if you’ll need hot water later.

Combi boilers are all-in-one heating systems that provide on-demand heating and hot water. This eliminates the requirement for a hot water cylinder to be installed.


Should I switch off my heater while on vacation?

If you’re going on vacation during the summer, it’s a good idea to switch off your boiler. Unless it’s for a really lengthy period of time.

Going away in the winter is a different story.

During colder months, turning off your boiler might cause pipes to freeze.


Is there a pilot light on your boiler?

The pilot light was a blue flame that was always lit in old non-condensing boilers. If you have a non-condensing boiler, you can view it via a tiny window on the front of the unit.

Because the pilot light never goes out, it’s constantly burning gas (which you pay for). When a non-condensing boiler isn’t in use, it’s a good idea to switch it off.

Replacing it with a condensing boiler is an even better option.

A pilot light is not used in condensing boilers. Electric ignition is used instead. This means your heating expenses won’t be inflated by a continually glowing pilot light.

In the United Kingdom, all new boilers must now be condensing. This has been the case for gas boilers since April 2005, and for oil boilers since April 2007.

The efficiency of condensing boilers is higher than that of non-condensing boilers. As a result, they use less fuel, which might help you save money on your heating expenses.

It’s time to replace your non-condensing boiler if you still have one.


Warming up the water

You should be able to get by without your boiler heating water if you have an electric shower and don’t take baths in the summer. You should be aware that tap water is not heated, which might be an issue if you wash your dishes by hand (although you can always use water heated in a kettle).



Many individuals are worried about the effects of shutting off their boiler on equipment such as washing machines and dishwashers. You should have no difficulties if you have cold fill appliances (or hot and cold fill), which is the situation with most new white goods. This is due to the fact that they utilise cold water and heat it with electricity rather than water heated by your heater.


In the summer, how should you care after your boiler?

Summer is a terrific time to save money by turning off your heating for a spell. Everything is, however, the greatest time to make sure it is ready for when winter returns.

And here’s how to go about it…


Keep an eye on it

You may switch off your boiler for a bit, but don’t leave it unattended. The valves or pump in your boiler might seize if you leave it unattended for weeks or months. And it’s possible that you won’t be able to get heat when you need it again.

Simply turn it on for a few minutes every now and then to prevent this.


Make plans for a service

A boiler service is required once a year.

It will not only assist in keeping your heating system functioning safely, reliably, and effectively, but it will also help to keep your warranty valid.

The summer is an excellent time to schedule a boiler servicing. That way, you can be certain that when winter arrives, it will be ready to keep your house warm.


Find a new one

You don’t want to have to replace your boiler in the middle of the winter. As a result, the optimum time to replace a boiler is during the summer.

When your present boiler has been heating your house for 10-15 years, you should consider replacing it. If you’re unsure when your boiler was installed, we can assist you in determining its age.

Even if your boiler is 15 years or older and seems to be in good operating order, replacing it is the best option. Modern boilers are more efficient, small, and quiet, in addition to making your house more pleasant.
