Typical Boiler Issues:

There’s No Hot Water And No Heating

If power is being supplied to your boiler and there’s no issue with your fuel supply (e.g. gas supplier or fuel storage tank)… and there’s no heating and no hot water then the first place to look is on the display panel of your boiler to check if an error code is showing. Also, check your thermostat settings are set correctly. Some potential sources of this issue could be: low boiler pressure; frozen condensate pipe; or a fault with the pilot light in the case of older boilers.

Look out for water leaks and always contact a professional Gas Safe registered heating engineer for assistance.

There’s Hot water But No Heating

A common issue is having hot water but no heating. This could be an issue with the boiler pressure being too low or an indication that you have a broken diaphragm and airlock, or an issue with diverter or motorised valves. Check the boiler pressure gauge; if it’s below 1 then your boiler may need more pressure. Check your boiler manufacturer’s instruction guide for reference on the recommended pressure level (typically between 1 and 2). If the pressure level looks in order and your thermostat is working, then a professional repair is likely required. Always make sure that you choose a heating company that is Gas Safe registered and provides a professional service you can trust.

Boiler Is Leaking Water

A leaking boiler is potentially a major issue as it’s most likely caused by a problem with an internal component, such as a worn-out pump seal or an issue with the pressure valve. A leak could be caused by a poor installation, an internal fault or corroded pipes and could be a sign you need a new boiler. If you are noticing water around your boiler, you should contact a Gas Safe registered heating engineer immediately.

Hearing strange noises

If you are hearing a strange noise emanating from your boiler, similar to that of a kettle boiling, then it could be an indication of limescale build-up. This can be an easy fix, and your engineer will be able to flush the system and remove the deposits. If you are hearing other strange sounds, it is best to speak with a Gas Safe engineer as soon as possible. Choose a reputable Gas Safe registered heating engineer to help repair the issue promptly.
