Fireplace and stove technology has come a long way in recent years. Modern stoves are designed to maximise effective combustion and can be very efficient.

All stoves on sale in the UK should include an efficiency percentage in line with British and European standards, representing the proportion of energy in a fuel transferred to heating the room.

The Solid Fuel Technology Institute publishes a register of more than 3,000 solid fuel appliances, including their efficiency percentage ratings.
