Boilers
Oil boiler repair
Oil boilers behave differently to gas, most call-outs come down to fuel supply, nozzle wear, ignition electrodes or a tired combustion chamber. We diagnose and repair oil boilers on properties across rural Warwickshire.
About this service
What this covers
Oil boiler repair covers pressure-jet kerosene boilers, internal and external, including Grant, Firebird, Warmflow, Worcester Greenstar Danesmoor, Boulter and Trianco.
Most oil boiler faults trace back to fuel supply, ignition, or combustion setup rather than the boiler electronics themselves. Proper diagnosis with a combustion analyser is essential, guesswork wastes oil and shortens component life.
Signs you may need this
- Boiler locks out on start-up and needs manual reset
- Sooting around the flue or in the combustion chamber
- Strong smell of oil around the boiler or tank
- Noisy start-up or 'puffing' on ignition
- Higher oil consumption than previous years
- Water in the oil filter or tank sight-gauge
What's included
- Fuel-line, filter and de-aeration check
- Nozzle, electrode and photocell inspection
- Combustion analysis and re-setting to manufacturer figures
- Report on tank and fuel-line condition
- Recommendations to prevent recurrence
