What a Comprehensive Boiler Service Includes
Our meticulous boiler servicing follows a thorough step-by-step process to ensure your system operates at peak efficiency, while complying with all current safety regulations. Each boiler checkup we undertake in Botley, Oxford and the surrounding area includes:
- Boiler Flue Output Check – We measure flue gas emissions to ensure combustion efficiency and compliance with legal safety limits. This includes testing for carbon monoxide leaks, which pose serious health risks.
- Pipework & Connections Inspection – Our heating engineers meticulously inspect all visible pipework, joints and seals for signs of leaks, corrosion or blockages, ensuring that your central heating system runs smoothly.
- Comprehensive Component Testing – Using state-of-the-art diagnostic tools, we examine:
- Heat exchanger condition to prevent efficiency loss
- Thermocouples, flame sensors and ignition system to ensure reliable startup
- Pressure relief valve operation to maintain system safety
- Circulation pump functionality to guarantee consistent heating performance
- Gas pressure and flow rate to confirm compliance with manufacturer specifications
- Disassembly & Internal Cleaning – Our engineers disassemble key components including the burner, fan assembly and heat exchanger, to remove soot, scale and debris that may reduce efficiency.
- Component Replacement – If necessary, we replace worn or faulty parts such as seals, electrodes and gaskets, using only manufacturer-approved components to maintain warranty conditions.
- System Reassembly & Final Testing – Once cleaned and reassembled, we perform a final set of rigorous checks, including system pressure testing, thermostat calibration and operational verification to confirm optimal performance.
