Repairing Older Gas Boilers

Some Hertford homes still run older boilers: floor-standing models in kitchen cupboards, and in some post-war houses, back boilers behind a gas fire. They can often be kept going, but parts are getting scarce and each repair needs an honest conversation about whether it is worth doing.

That is how we approach every older boiler. We find the fault, check whether the part is still available, and tell you plainly whether a repair makes sense or whether the money would be better spent on a replacement boiler. Newer combis and system boilers get the same careful diagnosis.

We work on mains gas boilers. If your home on the edge of the town runs on oil or LPG, let us know when you call and we will tell you straight away whether we can help. For our other local work, see our Hertford plumbing and heating page.

Older Boiler Faults We Repair

These are common faults on the older gas boilers still found around Hertford.

  • Pilot Light Going Out: Often a worn thermocouple or a draught problem. A quick repair if the part is available.

  • Back Boiler Faults: Failed thermostats and controls on back boilers, repaired where parts and safety allow.

  • Floor-Standing Boiler Problems: Burner and heat exchanger issues on older floor-standing models, assessed for repair or replacement.

  • Pump and Valve Failures: Circulating pumps and motorised valves that stop heat reaching the radiators.

  • Flue and Ventilation Issues: Older open-flued boilers need correct ventilation. We check this as part of any repair.

When to Call Us

Do not ignore these signs, especially on an older boiler.

Pilot Light Will Not Stay Lit

A common fault on older boilers that usually points to a worn safety device.

Yellow or Sooty Flame

A lazy yellow flame or soot marks mean poor combustion. Switch the boiler off and call us.

No Heat From the Back Boiler

When the radiators stay cold but the fire works, the back boiler or its controls may have failed.

Unusual Smells

Really happy with the work carried out by Alban Plumbing and Heating. They fitted several new radiators in my home and the whole process was smooth from start to finish. They arrived on time, were friendly and professional, and took great care while working in the house. The installation was completed to a high standard, everything was left clean and tidy, and the new radiators look fantastic and heat up perfectly. It's refreshing to find a company that is reliable, communicates well, and clearly takes pride in their work. I wouldn't hesitate to use Alban Plumbing and Heating again and would happily recommend them to friends and family.

Asif has done a great job looking after our plumbing and heating for several years now. He also recently attended in under an hour to fix an emergency leak that he and his son sorted with great efficiency allowing us to get back to work and continue operating with minimal disruption to our business and patients. He’s reasonably priced and friendly and I’m sure we will be using him for many years to come. His 5 star status is well deserved.
