Common Boiler Problems We Fix

Boilers can develop a range of faults, often at the most inconvenient times. Our experienced Befix engineers are equipped to handle all common (and uncommon) boiler issues, including:
  • No Heating or Hot Water: The most obvious sign something is wrong. We’ll diagnose the root cause, whether it’s a thermostat issue, pump failure, or something else.
  • Leaking or Dripping: Water leaks can cause damage and indicate internal problems. Don’t ignore them – call us for a prompt inspection.
  • Strange Noises (Banging, Whistling, Gurgling): Unusual sounds often point to issues like trapped air, low water pressure, or limescale buildup (kettling).
  • Pilot Light Going Out: If your pilot light keeps extinguishing, it could be a thermocouple fault or a gas supply issue that needs professional attention.
  • Losing Pressure: Boilers need to maintain correct pressure. If yours keeps dropping, there might be a leak in the system or a faulty pressure relief valve.
  • Frozen Condensate Pipe: A common issue in cold weather, preventing your boiler from working. We can safely thaw it and offer solutions to prevent recurrence.
  • Thermostat Issues: Inaccurate readings or unresponsive controls can prevent your heating from working correctly.
  • Radiators Not Heating Up: Cold spots or entire radiators failing to heat could indicate sludge buildup, airlocks, or balancing issues.
If you’re experiencing these or any other boiler problems, don’t hesitate to contact Befix.

Don't Wait for a Complete Breakdown – Signs You Might Need a Repair Soon

Sometimes, your boiler gives warning signs before it fails completely. Addressing these early can prevent a more significant breakdown and potentially save you money. Look out for:

Increased Energy Bills A sudden spike could mean your boiler is working inefficiently.
Takes Longer to Heat Up If your heating or hot water takes longer than usual, it might indicate an underlying issue.
Frequent Cycling The boiler turns on and off more often than normal.
Yellow Flame (Instead of Blue) This may mean incomplete combustion — a serious safety risk. Turn off your boiler immediately and call us.
If you notice any of these signs, it's wise to get your boiler checked by a professional.
