Gas Fire Efficiencies

Q: How can I compare the heating efficiencies of gas fires?

A: Efficiency is assessed by measuring the heat output from an appliance in kW against the gas input in kW.

For example, Gazco E-Box with balanced flue has an input of 4.10kW and output of 3.52kW, making it 86% efficient.

Further, as a general guide, glass–fronted fires are much more efficient than open fronted fires and, for glass-fronted fires, balanced flue versions tend to be slightly more efficient than conventional flue versions.

Information on efficiencies is given on each Product Page on this website.
