Potential Faults With The Heating System

If you’re having problems with your central heating system, there are a few potential faults that could be to blame. Here’s a quick rundown of some of the most common issues:

Boiler pressure

If the gas pressure in your boiler is too low, it won’t be able to heat your home correctly. You can check the pressure yourself using a pressure gauge; if it’s low, you’ll need to top it up.

The air within the radiators

Radiators can sometimes get air trapped inside them, which prevents them from heating up properly. To bleed a radiator, open the bleeder valve at the top until water starts coming out, then close the faulty gas valve again once the water is running clear.

Simple Checks To Identify The Underlying Problem

1. The indoor regulator needs temperature setting 

If your home is not being heated to the temperature you have set on your thermostat, you can check a few things. First, ensure that the batteries in your thermostat are fresh and working correctly. 

If the batteries seem okay, then it is possible that the indoor regulator needs some adjustment. This is usually a simple process of turning a knob or slider to the desired setting.

2. Timer

If you have a timer on your heating system, it’s possible that it has been turned off or is not set correctly. Check the timer settings and ensure it is on and set to the correct time.

3. Breaker box 

If your home’s heating system is not working, the breaker for the system may have been tripped. Check your home’s breaker box and reset any breakers that may have been tripped.

If your heating system runs on gas and it’s not working, it could be because there is no gas supply to your home. This is usually due to an issue with the main gas line, and you’ll need to contact your gas company to resolve the issue.

6. The boiler needs to be reset 

If your boiler is not working, it’s possible that it needs to be reset. Consult your boiler’s manual for instructions on how to do this. Once the boiler has been reset, it should start working again.

So what should you do if your boiler breaks down? The best action is to call a qualified heating engineer who can carry out the repairs safely and correctly. In the meantime, here are some tips on what not to do if your boiler breaks down.

  1. Don’t try to fix it yourself – as we mentioned above, boilers are complex machines requiring specialized training and repair experience. Attempting to fix your boiler yourself could be dangerous and void your warranty. Call a registered engineer to solve the problem
  2. Don’t turn up the heat – if your boiler is leaking or making strange noises, turning up the heat will only make the problem worse. It could be dangerous.
  3. Don’t ignore the problem – if you notice that your boiler isn’t working as well as it should be, don’t ignore the problem. Call a qualified heating engineer to come and take a look at it as soon as possible.

  5. Don’t forget to service your boiler – servicing it annually is essential to keep it running smoothly and efficiently. Getting your boiler serviced if you notice any problems is also a good idea.
