7 Red Flags: Is Your Boiler Losing Efficiency or Becoming Unsafe?
Don't ignore small faults that lead to expensive £500+ repairs. If you notice these signs in your Wokingham home, book a service today.
-
Banging usually indicates limescale buildup on the heat exchanger—a common issue in Wokingham’s hard water area.
-
A healthy flame must be sharp and blue. A yellow flame is a sign of incomplete combustion and potential Carbon Monoxide risk.
-
If you are using the filling loop weekly, you likely have a failing expansion vessel or a hidden leak introducing fresh oxygen (which causes internal rust).
-
"Heating sludge" restricts flow, forcing your burner to work twice as hard and spiking your gas bills.
-
A small drip today can short-circuit the electrical PCB tomorrow. Catching a failing seal early saves hundreds.
-
A dirty burner or scaled heat exchanger is literally "burning" money to reach the same temperature a serviced boiler hits in half the time.
-
A "rotten egg" scent indicates a gas leak; a metallic smell points to electrical overheating. Turn off the gas and call us immediately.
