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.
Combi boilers are ideal for smaller homes as they work as both a water heater and a central heating boiler, wrapped into one cost-effective unit. Combi boilers remove the need for any additional hot water cylinder or cold water tanks, meaning they can be installed neatly in your standard kitchen cupboard.
The Vaillant EcoFit Pure 825 combi boiler has a central heating output rating of 19.1kW, which is perfect for smaller homes with up to 10-15 radiators. It also has a hot water output of 25.2kW, ideal for homes with a single bathroom. The EcoFit Pure 825 is the least powerful in its range, therefore, if you feel that your home has a higher demand for heating and hot water, the EcoFit Pure 830 and 835 are also available.
