Boiler Advice For Freezing Conditions

Plumb-Call Plumbing & Heating Ltd

Do you worry that your boiler may throw in the towel under freezing conditions? Do you dread to think about the consequences?

January is the busiest month for boiler repairs, followed closely by February. 


When the weather turns nippy, people across the UK become reliant on their boilers to keep them warm. But some older boilers are susceptible to breaking down in sub-zero temperatures.

How to Minimise the Risk of Frozen Condensate

A frozen condensate pipe is the most common boiler issue during the cold winter months. This pipe, fitted to carry away water from condensation, often runs outside and can freeze during a prolonged period of cold weather.

Thankfully, there are some steps you can take to minimise the risk of this happening:


1. Prepare yourself for winter by insulating your condensate pipe with lagging that can be bought from any DIY store.

2. If there is a period of extreme weather, keep the heating on low all night to ensure the pipe doesn't freeze.

3. Reduce the amount of condensate by turning up the thermostat to a higher temperature. 


4. Ensure your combi boiler is well maintained and consider relocating the condensate pipe. Check out this blog to learn more about when to service your boiler and what warning signs to look out for.


How to Safely Thaw a Frozen Condensate Pipe

If the heating isn't turning on or there is no hot water, you may find yourself with a frozen condensate pipe. But don't fear, because you shouldn't need an emergency boiler repair.


You can check if the pipe has frozen by looking closely and locating where the problem lies. If it's frozen, you will be able to thaw it yourself with little difficulty.


Equip yourself with a hot water bottle, heat pads, a hot cloth, or warm water to gradually thaw it out. Be careful not to pour boiling water because this may cause the pipe to crack. If you boil the water in a kettle, wait at least 15 minutes before applying it to the pipe.

After the pipe is unfrozen, you can reset your boiler, and it should return to full function.


If this doesn't work, your pipe may have burst, and you should call a plumber to have it checked and repaired. If you are without heating or hot water in freezing conditions, we recommend that you stay in the warmest room of the house. Close the curtains, wrap yourself in lots of layers, drink warm beverages, and move a little to keep your body warm.


Freezing Conditions Need Not Lead to a Boiler Breakdown

A boiler breakdown in freezing weather is a nightmare scenario. But a frozen condensate pipe can be thawed in a matter of minutes, ensuring the continued operation of your combi boiler.
