There are a number of indicators that something is wrong and below we’ve listed some of the key indicators. Stop using your boiler and get it checked as soon as possible if:

• Yellow flame visible.
• Odd smells when boiler is running.
• General wear and tear.
• Leaking from unit.
• Radiators take a long time to get warm.
• Noisy boiler or system.
• Bills are increasing.
• Needs repairing frequently.
• Saving on bills.

An older, non-condensing boiler starts off at 80–85% efficiency, but may drop as low as 50% after years of use. A new combi boiler with a smart thermostat can achieve over 90% efficiency.

This means for every £100 you spend on gas, you could well be wasting over £40 just on running an inefficient boiler. This mounts up quickly, along with increasing repair costs.

A new A+ energy efficient boiler will often pay for itself in savings. The Energy Saving Trust says “If you replace your old model with an A-rated boiler and set of heating controls you could save about £340 (£28.33 per month) and 1,500kg of carbon monoxide a year”.
