Your gas-powered central heating boiler plays a vital role in keeping your home warm and cosy. Having confidence that your heating system is running efficiently, safely and economically in the winter months is of prime importance.

Moreover, it's about safety—ensuring your boiler is free from hazards like gas leaks and carbon monoxide leakages.

This guide will outline a few practical tips to keep your boiler running smoothly and safely.

What Is A Boiler Service?
“A boiler service is like a health checkup for your boiler.”

A Gas-safe engineer looks at your boiler to ensure it works well. They check things like the pressure and how the gas flows to make sure everything is just right. By giving your boiler a little health checkup, you can keep it happy and working properly.

During the service, the engineer will take off the boiler's cover to inspect its various parts, like the burner, heat exchanger, and spark sensor probe. They will also assess the gas rate, which is the amount of gas the appliance consumes.

An annual boiler service will maintain peak efficiency and the boiler's safety. Regular servicing often helps identify and address issues early, preventing costly breakdowns.
