COMMON PROBLEMS
Nunhead boilers and heating systems often present these signs of wear — our engineers can resolve them quickly:
No Hot Water or Heating
May be a broken thermostat, motorised valve, or pump failure.
Boiler faults
Could need bleeding, or there may be sludge in the system
Strange Noises
Banging, whistling, or gurgling can indicate limescale buildup.
Low pressure
Often caused by low water pressure or a blocked condensate pipe.
