An annual boiler service can help you to avoid any issues that may arise when it comes to turning your central heating back on during the winter months.

A boiler is one of the most essential appliances in your home, which is why it’s important that it gets serviced regularly so that it remains efficient and safe to use in your home.

Your boiler service must be carried out by a qualified Gas Safe Engineer. They will look at the full list of boiler components and carry out the necessary tweaks, replacements, or cleaning needed.

The boiler checklist will include the following:

  • Checking the flue system inside and outside the boiler
  • Checking the boiler flame
  • Removing the boiler casing to ensure that the burner, heat exchanger and spark electrode are working correctly
  • Check the case seal is still effective
  • Check the water-level control, low-water cut-off and safety valves are all in good condition
  • Firing up the boiler to check for any possible faults
  • Check that the expansion vessel is regulating the boiler pressure correctly
  • Clean any necessary parts

Your installer should leave you with a comprehensive list of checks in the servicing and maintenance section of the installation manual.

Having an annual service not only keeps your boiler nice and healthy and extends its lifespan but also saves you money on unnecessary future repairs that may be needed.

On average, a boiler service costs between £70 and £120 depending on your provider. For a one-off cost, it is worth checking that your boiler is in good nick for the next 365 days.

Thanks to its high-efficiency rating of 94% and an ErP A-rating for heat, the EcoTec Exclusive iQ 627 range is known for its reliability and efficiency. Thanks to these ratings, this system boiler could help reduce your energy bills, depending on your current boiler’s efficiency rating. 

The EcoTec Exclusive iQ 627 has an output rating of 26.7kW for central heating. This is powerful enough to heat a property with between 15 and 20 radiators.

It is important to note that when purchasing a new or replacement system boiler, an additional hot water cylinder will also need to be installed. These are typically located in an airing cupboard or similar. System boilers are fitted with a hot water cylinder to store the hot water that is heated in your boiler, for future use.
