Boiler repair FAQ's
Should I repair or replace my boiler?
Although there are not many boilers we can’t repair, sometimes fixing a boiler isn’t the best solution. This is usually the case when the boiler is around 10-15 years old as parts become harder to source and repairs are uneconomical. If we think this is the case with your boiler, we’ll quote you for a new boiler too so you can weigh up the options before deciding to go ahead with any work.
What are the common faults with a boiler?
Some of the most common problems with boilers include:
1. No heat or hot water – potential causes include broken diaphragms and airlocks, failure of motorised valves, issues with the thermostat or low water levels.
2. Leaking and dripping – a variety of issues could cause your boiler to leak water. It will depend on where the water is leaking from to determine the cause.
3. Strange banging, whistling or gurgling noises – air in the system is a common cause, alternatively it could be that the water pressure is too low or it’s kettling.
4. Pilot light going out – could be a broken thermocouple which is removing the gas supply to the pilot light, a draught blowing the pilot light out or a deposit built up in the pilot light.
5. Losing pressure – a water leak in the system is the most common reason for a loss of pressure. But it could also mean that the pressure relief valve needs replacing.
6. Frozen condensate pipe – Thawing a frozen condensate pipe should ideally be done by a qualified engineer.
7. Thermostat issues – if the thermostat is losing accuracy or turning the heating on/off when its not supposed to it might be time to invest in a newer, more energy efficient one.
8. Kettling – hearing a strange rumbling noise? When lime scale builds up on your boiler’s heat exchange the water flow is restricted. This water starts to heat and steam and the noise you get is referred to as kettling.
9. Radiators not getting hot – corroded pipework can cause sludge to gather in the system, preventing the free flow of hot water to the radiators. Chemically cleaning or flushing the system will remove these deposits.
10. Boiler keeps switching itself off – could be low water pressure, a problem with the thermostat or a lack of water flow due to a closed valve, air or the pump not circulating the water in the system properly.
