What are Signs of Boiler Trouble?

If your boiler’s actually stopped working, then it’s clear that you’ll need to call us. However, there are many less obvious symptoms that tell you something’s not quite right.

Look out for these signs of trouble:




  • Does the pressure dial on the front keep dropping too low? (It should normally rest at 1.0 – 1.5 bar when the heating is off.)
  • Is your water suddenly too hot or too cold?
  • Has the boiler lost its ability to differentiate between turning the hot water and heating on or off?
  • Are there strange clanking noises coming from the boiler itself, or does the pilot light keep going out?
  • How about a constant drip of water from a pipe that comes through the outside wall behind the boiler?

The Essence of Fault Finding

Fault finding is a crucial service for determining the origin of your boiler’s problem. An expert fault finder can identify the signs and symptoms displayed by your boiler, they can exchange various components according to the manufacturer’s instructions, they understand all of the errors and have intimate knowledge of different types of boilers.

The Need for Professional Repairs

Considering the importance of a boiler in terms of providing heat, comfort and hot water, it’s wise to use professional engineers for any repairs. Professionals understand how your boiler is supposed to tie into the plumbing system, they know the different brands and manufacturers and they have the proper tools and equipment to bring it all together safely. Whether it is a combi boiler, conventional boiler or system boiler, a reputable engineer is your best choice to have it repaired safely, effectively and quickly.

Whatever is wrong with your system, we’ll come over and have a look. Our team of Gas Safe experts will find out what the problem is and explain what is needed to fix it.

As our engineers carry all the necessary equipment to get boilers back up and running, we can fix many problems on the spot. If we need specialist parts, we’ll get them for you quickly. Our aim is always to get your boiler back up and running on the same day.

Because we’re accredited installers for almost all major boiler manufacturers, we’re familiar with the specification and workings of all of their boilers, from the very newest to those they made twenty years ago. That’s why you can trust us to repair or adjust them.

Don’t Forget Regular Maintenance

Keeping your boiler maintained is an effective preventative tool to avoid costly repairs and water damage. If you ask your engineer to help you set up a regular maintenance schedule, you can feel secure that each element of the boiler system is clean and functioning at full capacity when you need it most. Many people decide to forego this part of the process because they want to save money, but the small amount of money spent to maintain your boiler will save you even more money in the future. Your boiler will distribute heat more efficiently and it will last longer. To learn more about how we can help you with boiler servicing, click here.
