Boiler Repairs and Servicing

If you have a temperamental heating system, it makes noises, you have hot water in the header tank, you have cold radiators, or need to continually bleed them then our experts can help.

It doesn’t necessarily mean a whole new system is required, there are many reasons for any central heating system to degrade and we will advise on the best way to get your heating back to its maximum potential quickly.

Our engineers have previously worked directly for boiler manufacturers and have an in-depth knowledge of faults that occur with a range of boilers. No matter what type of boiler your household has, our team of experts can quickly diagnose and repair your boiler where viable, using quality components and parts. All work is covered with a 30 day labour and 1 year parts guarantee.

Having your boiler serviced regularly will ensure that it remains safe and runs efficiently, reducing the risk of a breakdown and prolonging the life of your boiler. Boiler manufacturers recommend that their appliances be serviced annually, and if your boiler is under warranty, you need to have an annual service to keep your warranty valid. A boiler service should only be carried out by a qualified and registered heating engineer.

What to expect from your boiler service from HEAT GB:

  • A visual check to ensure your boiler still meets current standards
  • Boiler fired to identify any working faults
  • Boiler casing removed to check all main boiler components (burner, heat exchanger, main injector, spark/sensor probe) and check safety devices are operating correctly
  • Checks to ensure flue terminals are unobstructed and internal flue components are sealed properly
  • Gas valve adjusted to check that burner is combusting efficiently and properly (using a flue gas analyser).
  • Inside casing surfaces cleaned
  • Boiler parts cleaned if necessary
  • Gas tightness test conducted to ensure no leaks
  • Boiler casing put back on - check that properly sealed
  • Older boilers and conventional boilers may not be serviced in the same way. Older conventional systems do not generally have their pump and / or expansion vessel contained within the boiler. In most cases they would be near the hot water cylinder. Also, parts like the burner and fan would need to be dismantled and checked. This would not be necessary for a modern boiler unless the flue gas analyser suggested there was a problem.
  • Which magazine has carried out boiler servicing trials and recommend that a boiler service should take a minimum of 30 minutes.
