Noises from the boiler are never a good sign of anything positive. They can be many and varied but the main thing to do is not to panic. Boilers are fitted with a huge amount of failsafes and cut off switches that ensure that nothing catastrophic is going to happen. However you should get it checked out and a regular annual service is the best way to make sure the boiler is operating in tip top condition. This is why a call to a Boiler Service Cheltenham based company is a really good idea.
One of the most unsettling and most common is that of a gurgling noise. Luckily this is also one of the least problematic issues and it is something that you can remedy yourself. This does not mean that you should start taking the front of the boiler off, there is no need to do that. If you hear a dripping or a gurgling it is most likely that air has become trapped in the pipes. Air and water should not be in the pipes together.
The remedy for this problem is the only one that is a “do it yourself” issue when it comes to boilers. The simple purchase of a radiator bleed key is all that is required. The next thing you have to do is bleed the radiators. All this entails is locating and turning a small valve at the top of the unit. As you release it a swoosh of air should come out. It’s really very satisfying. Keep going until water starts to seep and you are done.
