Boiler FAQs
Typical Boiler Problems we see across Redhill
- No Heat or Hot Water – Often caused by faulty motorised valves, broken diaphragms or airlocks, thermostat issues, or low water levels.
- Leaking or Dripping – A boiler leak can result from a variety of internal faults. Our experts will quickly identify the source and repair it safely.
- Strange Noises (Banging, Whistling, or Gurgling) – Usually caused by air in the system, low water pressure, limescale build-up (kettling), or pump failure in older boilers.
- Pilot Light Keeps Going Out – May be due to a broken thermocouple, a draught, or dirt build-up around the pilot light.
- Losing Pressure – Most often caused by a leak within the system or a faulty pressure relief valve.
- Frozen Condensate Pipe – A common winter problem that should be safely thawed by a qualified Gas Safe engineer.
- Thermostat Issues – An inaccurate or unresponsive thermostat can cause your heating to turn on or off unexpectedly; upgrading to a modern control can help improve efficiency.
- Radiators Not Heating Up Properly – Sludge or corrosion in the system can block the flow of hot water. A professional power flush can restore full performance.
- Boiler Keeps Switching Off – Can result from low water pressure, pump issues, trapped air, or a closed valve restricting water flow.
- Kettling (Rumbling Noise) – Caused by limescale build-up on the heat exchanger, often found in hard water areas.
