THERE’S nothing worse than getting up on a cold morning, turning the heating on – and nothing happens.

One of the most common reasons for this happens when it gets so cold that boiler pipes on the outside of the house freeze.

The issue will likely show up on the front of the boiler, via some error codes.

If that happens, don’t panic – and resist the urge to chuck a kettle full of boiling hot water over the pipes.

Instead, the boiler pros over at iHeat have explained exactly what to do, in a video on their TikTok page.

“First step is to fill a kettle,” they said.

“Make sure it goes to boiling and let it calm down for about 10 to 15 minutes. so it’s more lukewarm to the touch.”

After 15 minutes, take the kettle and pour the lukewarm water over the condensate pipe “from the top all the way down”.

“If you’ve got a soil pipe, make sure it goes onto the connection on the soil pipe as that can also be frozen with ice too,” the expert added.

And don’t panic if you start to see some ice come down from the bottom – that just means it’s working.

“Once you’ve poured it over a few times and you’ve made sure it’s all nicely covered, you want to head inside,” he continued.

“Turn your boiler off, wait a few minutes, turn it back on and hopefully all your error messages have cleared and your boiler is firing up fine.”

They also added in the comments that the clip was “just a quick fix for those waking up without heating who may not know what the problem is”.

“Save them an engineer call-out fee and wait times!” they added.

“Great tip!” someone else wrote in the comments section.

As another argued: “Why are you telling people this?

“You’re doing plumbers out of work?”

To which the iHeat pros replied: “We’re not about letting people pay an extortionate amount for a call out fee for a quick fix during a cost of living crisis!”
