Why Service Your Boiler Every Year?
An annual boiler service is one of the most important maintenance tasks a homeowner can carry out. It's not just about keeping your boiler running smoothly — it's also a safety requirement, a warranty condition, and a way to ensure your heating system operates as efficiently as possible.
Accredited regulations require that anyone carrying out work on a gas appliance — including servicing — must be registered with the the official register. Our engineers are all fully qualified and carry their ID cards at all times. You can always verify their registration at the official accreditation register.
What's Included in a RapidBoilers Boiler Service?
Check boiler casing, flue terminal, pipework, and any visible components for signs of damage, corrosion, or deterioration.
Remove and inspect the burner. Check combustion efficiency using a flue gas analyser to ensure the boiler is burning fuel correctly.
Inspect the heat exchanger for signs of cracking, corrosion, or debris that could affect performance or safety.
Check gas valve operation and test gas pressure at the inlet and throughout the appliance to manufacturer specifications.
Test ignition electrode and flame sensing probe. Clean or replace if necessary to ensure reliable ignition.
Test all safety interlocks, overheat thermostats, and pressure relief valve to confirm they operate correctly.
Check system pressure and test for inhibitor concentration. Top up inhibitor if required to protect the system.
