Average Efficiency From Domestic Air-Source Heat Pumps Outperforms Boilers by 5.37 Times

According to the latest figures, the average efficiency achieved by domestic air-source heat pumps installed by Harnitek in customers’ homes hit 440 per cent over the last year – meaning for every unit of energy going into the heat pump, 4.4 units are generated as heat output.

This is 5.37 times more efficient than a typical gas boilers, which average just 82 per cent efficiency according to figures, and 4.78 times more efficient than the 92 per cent figure most efficient modern A-rated boilers are advertised as being able to achieve. That means customers could save more money from the energy part, based on the rising energy prices.
