Signs Your Heating System is Broken and How to Fix it

radiator heating system

Dealing with technical problems that revolve around the use of a central heating system is quite tricky, especially if you don’t know the first thing to do when dealing with a mechanical breakdown. 

It’s recommended by companies who provide boiler repairs in Aberdeenshire to keep your heating system on even during summer to make sure it’ll still be working come wintertime. These professionals should also be the ones you call the moment you notice problems arising, so as not to aggravate it further and to keep it from collapsing completely.

Below, we’ve provided the most common signals to take note of when dealing with a failing heating system, and the corresponding ways you can solve them.

It’s Malfunctioning

To ensure you’re receiving your heating system’s full capacity, make sure your thermostat is working properly. Check for malfunctioning fuses as well. In usual cases, restarting your system is a good solution to check whether problems will continue to arise or not. You should also check your pumps for possible disturbances in your pipes.  

It’s Producing Heat Only on Certain Parts

When you notice your heating system is only warming up in the bottom, the only thing you have to do is turn off the pump, grab an empty bucket, and put it under the affected region of your radiator.

You then need to look for a square brass nut on one of the corners of your unit and turn it counterclockwise using a radiator key. Continue the movement until you hear air escaping and witness stained water has started to flow onto the bucket. You can then secure the valve back into place.

It has Different Temperatures

You might encounter heating problems where your radiator appears to be releasing cold temperature on the bottom part while producing warm temperature on top. This might indicate a muck build-up inside it. You need to remove it to keep your machine from crashing.

You can do this by removing your heating system from your wall and carefully emptying its water contents. And if that doesn’t work, you may be dealing with another problem which includes a worn-down pump, or a clogged pipe for that matter.

It’s Dealing with a Range of Noises

When your heating system starts to produce sounds similar to a kettle boiling, it could be due to enclosed air or obstruction due to stained water. Both problems can be solved by releasing the air or flushing out excess water.

It’s Overflowing with Water

Your heating system has a water tank to provide the appropriate water for your unit to work. Dealing with overflowing water means that there’s a blockage found in the ball-cock. You can fix this with the help of a professional because it will be hard to do on your own. 

Its System Pressure has Broken Down

Regularly checking your heating system’s boiler pressure gauge to make sure it’s functioning properly is one way to reduce problems. This way, you can also detect potential dangers that could damage your unit.


To avoid accidents when dealing with faulty central heating systems, you should turn to a user’s manual or better yet, call for expert help instead. This way, you don’t have to worry about managing the issues on your own and won’t have to resort to replacing your heating system.
