5 Common Reasons Why Your Boiler Isn’t Working
If your boiler suddenly stops working, it’s stressful—especially during a chilly Bedfordshire winter. At Nexus Plumbing & Heating, we’ve helped countless Biggleswade homeowners get their heating back on quickly. Here are five of the most common causes of boiler breakdowns:
- Low Boiler Pressure
If your radiators aren’t heating up and the pressure gauge is sitting below 1 bar, your boiler may simply need topping up. - Thermostat Issues
A faulty or outdated thermostat can stop your heating from turning on at the right time. - Frozen Condensate Pipe
A very common issue during cold snaps. A frozen condensate pipe can stop your boiler from working completely. - Pilot Light or Ignition Problems
If your boiler keeps failing to ignite or the flame won’t stay on, it may be due to a faulty ignition system or blocked jet. - Worn-Out Components
Over time, pumps, fans, and valves wear down. Regular boiler servicing can prevent unexpected failures.
