Suspect that you’ve got something wrong with your boiler? It could be one of these common problems:
- Not getting hot water or heat
This could be the result of a faulty diaphragm and airlock, broken valves, low water levels or a problem with the thermostat. The first thing to check is the pressure of the boiler or the thermostat. If you suspect you might have broken parts, contact a Gas Safe engineer to diagnose and replace parts for you. For Boiler Installation Forest Of Dean, contact http://greenplanetheating.org/
A number of issues could be causing a leaky boiler. Often, it’s down to a broken part but should the leak seems to be originating from the pressure valve, the boiler’s pressure is probably too high. Coming from the pump? It’s probably old and needs replacing. Leaking from the pipes or tank could mean corrosion or a poor installation. Always get a Gas Safe registered engineer to take a look.
Can you hear a noise that sounds a bit like a kettle boiling? This is often the result of an accumulation of grime or limescale on the heat exchanger inside the boiler. This causes a blockage, restricting the water flow and causing it to boil or steam. Leaving this issue can shorten the life of your boiler, so it’s advisable to call an engineer who can flush out the system for you.
- Pilot light extinguishes
If that small blue flame keeps going out, it might be the result of a worn-out thermocouple, a draught or build-up of deposits on the pilot light. If none of your other gas appliances are working, there could be a supply problem, so contact your gas supplier.
- Low Boiler Pressure
Checking your boiler pressure is simple, just look at the pressure gauge. If the needle is below 1, you could well have a low-pressure issue and your heating system isn’t working properly. This could be down to a leak, the need for a replacement relief valve or that you’ve recently bled your radiators. If you don’t feel confident in re-pressurising the system yourself, call an engineer.
- Frozen Condensate Pipe
Any type of condensing boiler will have a condensate pipe for transporting acidic water away from the boiler. The pipe usually runs into an outside drain and exposure to freezing conditions in winter can cause the pipe to freeze over.
Thawing a condensate pipe can be done with a hot water bottle, warm cloth or microwaveable heated pack. You can also pour warm water over it, but never boiling hot water. Once thawed, you might need to reset the boiler to get it going again.
Remember to never carry out work on a gas appliance but call a Gas Safe registered engineer.
