How can I improve the efficiency of my boiler?

This April, it was reported by Ofgem that more than 50% of UK households would see a considerable hike in their annual gas and electricity payments.

This poses a significant challenge to Brits, who are increasingly looking to reduce their annual energy bills by improving the efficiency of their boiler units.

But how exactly can this be achieved? We’ve produced a handful of tips to help you get started below!

Arrange an Annual Service

Let’s face facts; there’s a reason why we call on accredited plumbing and heating engineers to handle our boiler repairs.

More specifically, qualified engineers are able to diagnose and repair even the most complex and seemingly innocuous issues, whilst they’re also fully qualified to work safely and with due care.

With this in mind, one of the best ways of optimising the efficiency of your boiler is by arranging an annual service, ideally towards the end of the summer.

This way, an engineer can identify any issues that may be impairing your boiler’s performance and efficiency, before carrying out skilled repairs.

Keep your Boiler Clean

This may sound like a strange one, but the fact remains that keeping your boiler clean can help to prevent pipes from becoming clogged and minimise your monthly heating bills.

So, be sure to dust your boiler and prevent debris from settling whenever you clean your house, whilst leaving the experts to inspect your heating system’s interior.

If an engineer decides that the boiler unit has become hampered by a blockage or the accumulation of sludge and debris, they may also recommend cleansing it with a so-called ‘powerflush’.

Monitor the Pressure

The pressure gauge can offer an insight into the efficiency of your boiler, whilst various issues can impact on this at different times of the year.

Ideally, the pressure gauge will read 1.5 bar when it’s operating at the optimal level of efficiency, but this can easily drop in instances where the boiler has been switched off for a while. Conversely, the pressure can increase when there’s air trapped in the system, but either way you can take steps to correct this issue. 

This is certainly true if the pressure is too high, as bleeding your radiators and releasing trapped air from the system can quickly improve the performance of your boiler.
