  • Leaks from pipework, connections, pumps, or internal seals
  • Noisy operation, including banging, rumbling, or vibrating
  • Faulty thermostats or control boards
  • Hot water shortages or temperature fluctuations
  • Boiler lockouts caused by safety system activation

As part of our boiler repairs service, we also work on all major makes and models of combi, system, electric, and oil boilers, including products from:

Time to Call in a Gas Engineer

Some faults reveal themselves immediately, while others develop slowly and only show subtle symptoms at first. Calling a 3Heat Plumbing & Heating gas engineer early helps prevent further damage and keeps repair costs down. Look out for these warning signs:

  • Radiators taking a long time to warm up
  • Boiler frequently switching off or failing to ignite
  • Water temperature changing unexpectedly
  • Sudden increases in energy bills
  • Unusual noises, rattling, or vibrations
  • Persistent error codes appearing on the display panel

Any of these symptoms could indicate a faulty boiler requiring professional attention. We assist households and businesses in and around Bristol, Chew Magna, and Radstock every day, providing clear diagnostics and trustworthy repair advice you can rely on.
