Causes of a leaking combi boiler

At this time of year the heating is used much more frequently, and for longer periods of time. But this means that your boiler needs to work overtime, which could lead to issues, especially if your boiler hasn’t been serviced. One of the biggest problems is a boiler leak. But what causes these? And what can you do? Well, here at Charter Heating, we are leading boiler, heating and gas experts. As a result, we have produced this guide to everything you should know about combi boiler leaks.

So, what are the most common causes of a leaking combi boiler?

There are a number of things that can cause your combi boiler to leak. These include:

  • A pipework problem- if your combi boiler is leaking from underneath, the problem could be a corroded pipe, or faulty pipework. The pipework will become corroded over time, so if your boiler is quite old, this could be the culprit. However, if your boiler is quite new, a faulty join in the pipework could be an issue.
  • Too much water pressure- If your boiler water pressure is too high, the pressure release valve will open to drain the pressure, or the internal parts will fail, causes water to leak through the boiler. This is something that can easily be prevented, by reducing boiler pressure when it gets too high, and checking the pressure gauge frequently.
  • A broken heat exchanger- the heat exchanger is one of the most expensive components of a boiler, and this is not something you will be able to fix yourself. Over time, they can crack and break, which can lead to a boiler leak and potentially lots of boiler damage.
