Energy-saving credentials have made condensing boilers very popular over recent years. Unfortunately, when the condensate pipes attached to these boilers are exposed to cold weather, they have a tendency to freeze.
Current building regulations allow boiler condensate pipes to be routed outside, which means that they often have to endure low temperatures. If you have an external condensate pipe, read on for simple instructions on how to defrost your pipe safely, and learn how to stop it from freezing again next winter!
Prevention is always better than a cure - the last thing you want is to be left in the cold with a frozen condensate pipe! Luckily, MyBoilerService is here to help. Check out our top tips to prevent pipe disasters this winter:
If possible, reroute your condensate pipe to avoid exposure to outside temperatures.
Have your pipe replaced with a larger pipe, which is less likely to freeze in cold weather. (a minimum of 32mm in diameter).
Purchase an alarm for your condensate pipe, which will warn you if your pipe begins to freeze.
If you are unable to replace or relocate your pipe, add a layer of insulation to exposed areas instead.
If you have an external condensate pipe, make sure it slopes downwards and is as straight as possible.
Purchase a condensate heating device to prevent ice build-up.
If you've thawed your pipe but are still experiencing problems, the best thing to do is to book an emergency repair with a qualified engineer.
