5 Common Issues With Home Boilers

Boilers serve a crucial function in the home. However, they do break down from time to time. And, if you ignore the issues, it will typically lead to a bigger and costlier problem. Below are five of the most common boiler problems you should be familiar with. 


Most boiler leaks originate inside the boiler, typically at the pump seal or pressure valve. If the pressure relief valve is the source of the leak, then the pressure in your system is likely too high. Pump seal wear might account for the leak.

It’s also possible that corrosion in the pipes is to blame for the leak in your system. A problem with the installation procedure is also probable. An experienced engineer should be consulted for assistance with this kind of problem. In extreme cases, the professional may advise replacing the boiler as the only solution to stop the leak.

Low Boiler Pressure

If the pressure in your boiler is too low, you can typically tell by looking at the gauge. The ideal pressure for a boiler is 1.5 bars. The boiler will stop working properly if it drops below 1. 

A leak in the system, recently bled radiators, broken parts, or a faulty seal are all potential causes of low boiler pressure.

You might start by searching for obvious leakage indicators, but you shouldn’t try to remove any boiler casings to diagnose the problem. A specialist should be called in if a leak is discovered.

Frozen Condensate Pipe

This problem often occurs, especially during the winter months. The condensate pipe in your system is in charge of transferring condensate from the boiler to the outside drain. The condensate may freeze during cold spells, resulting in a clog. 

This is most frequent when your condensate pipe is installed outside or in an unheated room like a garage. Because of this problem, condensate may flow backward into the boiler, which might cause the boiler to fail.

Boiler Doesn’t Turn On

The first thing you should do if your boiler won’t switch on is to ensure everything else is functioning correctly and receiving electricity. If they are, you should inspect your fuse box for faulty or tripped switches.

Boiler And Thermostat Problem

Check the thermostat’s time is in line with the present. Your boiler’s controls may be damaged or outdated if it’s entirely unresponsive to the thermostat. Before you conclude that it is fully broken, there are some tests that you can do to ensure that it is not.

Importance of home maintenance trouble shooting – If your boiler turns on but quickly shuts off, the problem might be caused by low pressure or a clog. If the pressure gauge shows less than 1, you should repressurize the boiler.

You should seek the assistance of a skilled professional if the problem persists. It is best to go for a local plumber for a more likely quicker response, for instance a plumber Bradford based is likely to be called for plumbing issues within Bradford.

For example, you can try to replace the batteries. You can also try to move the thermostat closer to the boiler. Identify any potential sources of interference and eliminate them. Review the thermostat’s user manual or contact the manufacturer if the issue continues.

Of course, you can do a bit of fixing. However, if you think that the problem is serious, it’s always best to consult with a professional.

Like most things in life, it’s only a matter of time that your boiler will have some kind of malfunction. If you own a good quality unit and you keep up with the maintenance, the problems are typically minor.
