Common Issues with Gas Central Heating Systems

While gas central heating systems are the most popular of all the home heating options, like any other complex system, they can go wrong. Here are a few of the common issues that can develop with a gas central heating system.

  • Faulty Thermostat – If your thermostat is inaccurate, this can result in using far too much fuel, and when the heating engineer does a gas boiler service in Edinburgh, he would check the accuracy of the thermostat.
  • Air in the System – The water in your central heating system is locked and it loops the system continuously, and should air get into the system, this will result in a loss of heat in some of the radiators. The heating engineer has a special tool to bleed the air out of the system.
  • Corrosion – The pipe joints can become corroded, which might lead to a water or even gas leak. Every time your central heating is serviced, the engineer would closely inspect, looking for signs of corrosion.
  • Boiler Issues – The burner can sometimes malfunction and if it gives off a yellow flame, this means the burn is not good and you are wasting energy. The boiler could develop leaks, and after 10-15 years, a boiler in need of repair is better replaced than fixed.
  • Sludge in the System – This is particularly common in old central heating systems, and the best solution is a power flush, which removes the sludge and that optimises the system’s performance.

If you have yet to have your gas central heating serviced this year, an online search will help you locate a local heating engineer.
