Primary 5 Common Boiler Issues

1. Little Heat or Hot Water

Possible causes consist of broken diaphragms and airlocks, failure of motorised valves, concerns with the thermostat or low water levels. A great location to begin is to inspect if your boiler is not working because of an issue with boiler pressure or your heat regulator.

If you believe you may have a damaged diaphragm, airlock or valve it might need to be replaced with a new part. We suggest calling out a Gas Safe registered engineer who will be able to thoroughly identify the issue and replace any broken parts where needed.

2. Dripping and Leaking

A range of concerns might trigger your boiler to leak water. It will depend on where the water is leaking from to identify the cause-- nevertheless you need to never ever attempt to repair a leaking gas boiler yourself, always call out a Gas Safe signed up engineer.

The most common cause is a broken internal element, such as a pump seal or pressure valve. If the leakage is originating from the pressure valve it might be a case that your boiler pressure is expensive. If it's coming from the pump seal, it may have become worn out and need changing.

You may likewise discover your boiler is leaking around the pipes or tank-- this can be a result of deterioration or in some cases where the system has not been fitted appropriately. In any case, we suggest calling out an engineer who will have the ability to diagnose and repair the issue for you (in in the worst case advise if you require to replace your boiler).

3. Kettling

Hearing a weird rumbling noise similar to when a kettle is boiling? When lime scale or sludge develops on your boiler's heat exchanger you can get something called kettling. When these deposits develop in your boiler, they can limit the flow of water within the heat exchanger. This can get too hot the water, causing it to steam and boil (triggering the kettle-like noises).

Kettling is more typical in locations with hard water, however can likewise affect boilers in soft water areas. Not only does it trigger your boiler to work harder and thus cost more to run, it can also reduce the system's life. If your boiler is kettling, it's suggested to call out a gas safe authorized engineer who will likely eliminate your system to eliminate the accumulation of these deposits and guarantee the system is working effectively again.

4. Pilot Burner Goes Out

The pilot light is a little blue flame that's kept alight to light a bigger burner. If it keeps gong off then it could be brought on by a broken thermocouple stopping the gas supply, a draught blowing the pilot burner out or a deposit developed in the pilot burner.

Before attempting to reignite the pilot burner, it's extremely crucial to check that there aren't any problems with the gas supply. If your gas stopcock is on however your boiler isn't getting any gas, or if none of your other gas home appliances are working, then you must contact your gas provider. You can then attempt relighting the pilot burner yourself-- guaranteeing you follow the directions discovered in your boiler's handbook for firing up the pilot light.

If neither of these things work you must call out a Gas Safe signed up engineer. Always keep in mind that you need to never perform any work on your own gas boiler.

5. Low Boiler Pressure

Checking the pressure of your boiler couldn't be simpler, just have a look at the built-in pressure gauge. If you find that the needle is below 1, then there might be a problem with low boiler pressure and your central heating system will not operate correctly.

There a number of reasons that this may be happening:

- A water leak in the system

- The pressure relief valve needs replacing

- Just recently bled radiators

You must begin by looking for a noticeable leak in the system, if you discover one then call a registered engineer, if not, you could attempt re-pressurising the system. If you do not feel comfortable doing this then get in touch with a professional but if you want to try then it is very important to follow the directions in your heating unit' manual.
