Why does boiler efficiency matter?

A boiler's efficiency relates to the amount of energy it uses when it comes to heating water.

For example, if 95% of the energy used heats the water, this means that 5% is lost, which would represent an energy-efficient boiler. However, a boiler that loses 40% of its energy would not be very energy efficient.

Considering that you pay for 100% of the energy used regardless of how much is wasted, it's wise to ensure your boiler is as energy efficient as possible.

What do boiler efficiency ratings mean?

Boilers are either rated according to the ErP or SEDBUK systems.

ErP is the European rating system for boilers, rating their efficiency from A to G. All UK modern gas boilers are legally obligated to be A-rated - i.e. as efficient as it's possible to be.
