Combi Boiler Maintenance

Boiler maintenance need not be a complicated subject!  We've broken it down into 4 crucial overall topics, and then offered some of the ways you can check whether you need to call out a professional.

To keep you safe, we have excluded those that should only be checked by a registered Gas Safe engineer.

  • Safety: Regular maintenance helps identify and resolve potential safety issues, such as life threatening gas and carbon monoxide.
  • Efficiency: Properly maintained combi boilers works efficiently, use less energy and ultimately SAVE you money.
  • Longevity: Yearly maintenance increases the life-span of your combi boiler and its components, avoiding a costly replacement.
  • Warranty: Most combi boiler manufacturers REQUIRE you to perform yearly maintenance to stay within warranty or guarantee

Your at-home checklist!

  • Check For Leaks: Frequently check for any visible leaks in the system. Leaking water or gas can be dangerous.
  • Monitor Pressure: Check the pressure gauge on the front. It can be a sign of a problem if it’s continuously too high, too low or inconsistent
  • Radiator Bleeding: If you feel cold spots on your radiators, it’s time to bleed them. Releasing trapped air, maintains the effectiveness of your heating system.
  • Strange Sounds: Whistling, banging or knocking may indicate internal issues with your boiler.
  • Flue & Ventilation: If possible, check outside to see if they are blocked. Blocked vents may cause a carbon monoxide build up.
  • Thermostat: Make sure the thermostat is working properly. Installing a programmable thermostat will offer more precise control & energy savings
  • Annual Service: You should have your boiler serviced annually by a Gas Safe registered engineer. They will conduct a full exam, clean, and make any necessary adjustments.
  • Keep Records: Our engineers will leave you with a log of what they found, fixed and recommended. This can identify issues over time and help with warranty claims.
