Now that the nights are drawing in, and the temperature is certainly dropping, many of us have already opted to turn the heating on. But after a long summer with warm temperatures, and no need for the heating, some central heating systems might not kick back into life like they used to. And this could indicate a potential problem with your boiler, or your central heating system. Either way, you’ll need to get in touch with a professional to have this checked out. Here at Paul Robinson Heating and Plumbing, we are leading central heating and boiler experts. As a result, we have produced this guide to common problems with your central heating system.

What are the most common problems with central heating

There are many factors that can cause a problem for your central heating system. These include:

  • your radiators
  • the central heating pump
  • thermostat
  • the boiler

You radiators

If you are turning the heating on, but your radiators aren’t getting warm, there are several different factor that could be causing this issue. So first of all, you should check out your radiators.

Radiators need bleeding annually, to keep them working to the best of their ability. And to prevent any build-ups or deposits from blocking the path of the hot water around your system. If you have hot water, but your radiators aren’t getting warm, you should definitely get an expert to bleed them.

Sludge can also build up in the centre of the radiator, so if your radiator is warm at the top and the sides, but cold in the middle, it could be hitting a patch of sludge. To solve this issue, your radiators will need power flushing.

Central heating pump

This pumps water from the boiler around the radiators and back to the boiler. This needs to be plugged into the mains to work and if this is broken you may not be able to heat your radiators.


If you are turning your thermostat up, but getting no response, your problem could be with the thermostat itself. And this means that an expert will need to find out what exactly is going wrong. It could be the thermostat has developed a fault. Or even that the thermostat and the boiler are no longer communicating effectively.
