A gas boiler service or a LPG boiler service (depending on which system you have) is essential for ensuring safety, efficiency, and reliability. It should be carried out annually by your Perceptive Heating Engineer and includes several key checks, tests, and cleaning procedures: 1. Visual Inspection •Check for leaks, corrosion, or damage on the boiler, pipework, and surrounding area. •Inspect the flue and ventilation for obstructions or damage. •Ensure compliance with gas safety regulations. 2. Operational & Control Checks •Test the boiler start-up sequence and monitor for unusual noises or vibrations. •Inspect and test thermostats, timers, and pressure gauges. •Verify the correct operation of safety devices (e.g., pressure relief valve). 3. Gas & Combustion Tests •Conduct a flue gas analysis using a gas analyser to check combustion efficiency. •Check for carbon monoxide (CO) leaks and ensure safe flue operation. •Inspect and adjust the gas pressure and flow rate. 4. Cleaning Components •Clean the burner and heat exchanger to remove soot or deposits. •Clean the condensate trap (for condensing boilers). •Inspect and clean electrodes and ignition components. 5. Condensate & Seals Inspection •Check the condensate pipe for blockages or freezing risk. •Inspect all gaskets and seals for wear and tear. 6. System Pressure & Expansion Vessel •Check and top up the system pressure. •Inspect the expansion vessel and recharge if necessary. 7. Gas Safety Checks •Optional gas tightness test to ensure there are no leaks in the system. 8. Final Testing & Report •Restart the boiler and check for correct operation. •Provide a service record or certificate with recommendations for any required repairs or improvements. ________________________________________ Why is an Annual Gas Boiler Service Important? ✅ Safety – Detects gas leaks and carbon monoxide risks. ✅ Efficiency – Improves performance and lowers energy bills. ✅ Reliability – Reduces the risk of breakdowns. ✅ Warranty Compliance – Many manufacturers require annual servicing to keep warranties valid
