Troubleshooting Guide
Common Boiler & Heating System Faults
Recognize these common heating symptoms? We fix them all with a fixed £79.00 diagnosis & call-out fee.
Low Boiler Pressure Fault
Pressure gauge reads below 1 bar causing boiler lockout. Usually indicates a leak in radiators, failed pressure relief valve (PRV), or depleted expansion vessel charge.
Air Source Heat Pump Issues
Heat pump displaying error codes, failing to reach target water temperatures, or icing up continuously. We carry out full flow rate and inverter diagnostics.
Heating On, But Cold Hot Water
Heating works fine but tap water remains lukewarm or cold. Classic indicator of a sticking or failed combi boiler diverter valve motor/cartridge.
Noisy Boiler & Kettling Sounds
Loud banging or kettle-boiling noises coming from boiler unit. Indicates heavy limescale deposits on the primary heat exchanger or failing circulating pump.
Water Dripping Under Boiler
Water dripping from lower casing or copper discharge pipe. Caused by corroded O-rings, blown auto air vents, or passing pressure relief valves.
Commercial Boiler Breakdown
Commercial plant room lockout or manifold controller error in commercial premises across Knowle.
