Common Boiler Repairs & Signs to Watch For

Low Boiler Pressure
- Sign: Your boiler might shut off unexpectedly or fail to heat your home properly. The pressure gauge will show below 1 bar.
- Solution: Our engineers will check for leaks in the system and restore the correct pressure levels.
Leaking Boiler
- Sign: Visible water around the boiler or drips from internal parts. This could be due to corroded pipes, a broken pump seal, or high boiler pressure.
- Solution: We’ll identify the source of the leak and carry out necessary repairs to prevent further damage.
Pilot Light Going Out

- Solution: We’ll inspect and repair the faulty parts and ensure your boiler is firing up safely and reliably.
No Hot Water or Heat
- Sign: The boiler is on, but there’s no hot water or heating. This could be caused by issues with the diverter valve, thermostat, or even the pilot light.
- Solution: We diagnose the faulty component and replace or repair it to restore your system.
Strange Noises
- Sign: Banging, whistling, or gurgling sounds from the boiler. This often signals air in the system, low water pressure, or a pump failure.
- Solution: We’ll bleed your radiators, check water pressure, and examine the boiler’s internal components to eliminate the noise.
