Top Ten Most Common Boiler Problems

Most of us take our boilers for granted until they stop working or develop a problem of some kind. So with that in mind, we’ve compiled a list of the top ten most common problems your boiler is likely to have. Keep an eye out for them.

1. No heat.

There are a range of reasons for this so the solution is to call out an engineer to find the cause.

2. No hot water.

Again, many reasons can cause a loss of hot water, so ask your engineer to find out what the problem could be.

3. A loss of pressure.

Most often a leak is the cause of this problem.

4. A lack of regular inspection.

This is a big cause of all kinds of problems, simply because the owner hasn’t invested in an annual service. This can prevent all kinds of problems from occurring in the first place.

5. Frozen condensate pipe.

If the temperature drops outside and the pipe freezes, it will create a blockage. This means the boiler will stop working until the pipe is properly defrosted.

6. No heat in the radiators.

A system flush can solve this, as it will flush through the pipes and clear them out. A worn out pump can also be the cause.

7. Thermostat problems.

All kinds of things can go wrong with the thermostat. Some can be resolved by the attention of an engineer, while on some occasions it is best to replace the boiler.

8. Kettling.

It sounds odd but it is caused by an excess of limescale in your boiler. An alarming banging sound can indicate this.

9. A rise in pressure.

This is the opposite of loss of pressure, in that in this situation there is too much water in the system instead of too little.

10. No pilot light.

There are several causes for this as well, so again, call out a qualified engineer to resolve it for you. A replacement part might be required.

You can probably see that the solution to any boiler issues you get is to call out a qualified engineer. They should be Gas Safe registered and able to resolve any issues you come across. But remember, a regular annual inspection can prevent many issues from occurring in the first place, so don’t skimp on getting this important service done each year.
