What temperature do house pipes freeze at? See heating guide

With the cost of living getting considerably tighter towards the end of the year due to Christmas expenses, having to repair or replace a pipe after it’s expanded and burst due to freezing water could be costly.

However, when it comes to avoiding frozen pipes, you might be wondering what temperature they can freeze at and if keeping the heating on can prevent such problems from happening throughout the colder months.

Let’s see what the property and energy experts have recommended.

Is it cheaper to keep the heating on low all day?

What temperature do house pipes freeze at?

“Water freezes at 0C, but when it comes to pipework, it’s not quite as simple as that,” explains Martin & Co.

“The colder the temperature outside, the greater the chance of an ice blockage in your pipes, but the exact temperature they freeze at can vary.

“Pipes exposed to cold draughts or breezes can sometimes start to freeze at higher temperatures.”

The estate agents add: “You may have heard the phrase ‘wind chill’ when watching the weather, where the temperature could be well above freezing, but the cold wind and air makes it feel much colder.

“Pipes are affected in the same way and those that are protected from cold air may take a much lower temperature to freeze."

Does keeping the heating on stop pipes from freezing?

As well as letting your taps drip now and again to make sure water is flowing, keeping your heating on at home can also prevent pipes from freezing.

Martin & Co says: “A consistent temperature in your home is arguably the best way to stop pipes from freezing and bursting.

“If you leave your property for any length of time, set your thermostat to maintain a consistent temperature while you’re away – this doesn’t have to be at the level you would normally heat your home, but should be warm enough to stop pipes freezing over.”

What temperature should I keep my house at so the pipes don’t freeze?

British Gas advises: “When it’s frosty outside, you need to make sure it doesn’t get too cold inside to stop your pipes from freezing.

“We recommend keeping your thermostat set to at least 7C - even if you’re not at home.

“The Hive Thermostat has a built-in Frost Protection feature which automatically turns your heating on if the temperature drops below 7C.”
