Boiler Servicing
A Boiler Service keeps your heating system running safely and efficiently without disruption.
Here’s what happens during a typical Boiler service:
- Visual inspection: We assess the Boiler and pipework. Looking for signs of damage, leaks, corrosion, or incorrect installation.
- Boiler casing removal: The outer casing is taken off to access all internal components safely.
- Internal component check: We inspect the burner, heat exchanger, spark electrodes, condense trap, seals, and all moving or heat-affected parts.
- Deep cleaning of key components: Soot, dirt, and buildup are removed from the burner, heat exchanger, and internal surfaces.
- Gas rate and combustion testing: We analyse how the Boiler burns fuel to ensure clean, safe, and efficient combustion.
- Flue inspection and testing: The flue is checked for blockages and correct extraction of gases.
- Carbon monoxide and safety tests: We run full CO checks and verify all safety systems work.
- Airflow and ventilation checks: We check the correct airflow and ventilation.
- Pressure checks: System pressure, expansion vessel performance, and pressure relief components are tested. Necessary adjustments are made to restore correct performance.
- Condensate system check: The condensate pipe, traps, and drainage are inspected to prevent blockages or leaks.
- Electrical safety checks: Wiring, connections, sensors, and controls are checked.
- Operational test: We fire the Boiler and run it through a full operational cycle, checking for correct ignition, steady running, stable temperature control, and proper shutdown.
- Service record completion: We document all test readings, work carried out, and any recommendations.
Boiler Repairs
We have repaired many Boilers in Leiston. Our repair services include same-day response with no call-out charges.
Here are typical Boiler issues and solutions:
- Low Boiler Pressure: We’ll check for leaks, repressurise the system, test the expansion vessel, and restore pressure so your heating stays consistent.
- No Heating or No Hot Water: We diagnose the root cause. From valves to pumps to sensors. Replace faulty parts, and get heat flowing again fast.
- Ignition & Pilot Light Failures: We clean or replace ignition electrodes. Check the gas supply. Reset the ignition sequence and ensure the Boiler fires up safely.
- Boiler Leaks: We locate the source (valves, seals, heat exchangers). Replace worn components to stop the leak.
- Kettling & Noisy Boilers: We flush out limescale, check the heat exchanger, and clear blockages. Silencing the Boiler so it runs quietly at optimal performance.
- Thermostat Problems: We recalibrate, repair, or replace faulty thermostats so your Boiler responds to temperature changes. Heating your home to the right level.
- Frozen Condensate Pipes: We’ll thaw your pipe, insulate exposed sections, and improve drainage. Stopping the pipe from freezing again.
- Radiators Not Heating Evenly: We bleed radiators, balance the system, and clear sludge so every room heats consistently.
- Frequent Boiler Cycling (turning on/off): We check sensors, thermostats, flow switches, and system pressure to prevent short cycling and reduce wear.
- Pump Failures: We repair or replace faulty pumps. Restoring circulation throughout your heating system.
- Faulty Motorised Valves: We unstick, repair, or replace valves so hot water flows exactly where it should. No more lukewarm radiators or tanks.
- Error Codes & Lockouts: We read the diagnostic codes, reset the system, replace failed components, and prevent repeat lockouts.
