  • How to check Fans on Boilers for Heating Engineers

    To test a fan speed resistor: Electrically isolate boiler / system controls. Remove leads from resistor. Set multimeter on ohms scale for resistance readings, across resistor connections: No resistance/infinity = faulty. Resistance reading (may vary) = ok. A bad connection will increase resistance and as a result may drop the fan speed Learn More

  • Boiler Overheating: Causes, Signs & How to Fix It | Boiler

    Limescale build-up on the heat exchanger can restrict the flow of water and lead to your boiler overheating. The heat exchanger's role within the heating system is to heat cooler water before it's then circulated around the radiators. Not only putting the boiler at risk of overheating but could also reduce the lifetime of the boiler.Learn More
