Efficiency Comparison Chart

This chart show what percentage of your £1 will be used to produce heat in your pool.

Heat pumps don't have a simple efficiency number to work with.

Their efficiency is measured by coefficient of performance (COP). Water heat pump's COP ranges from 4.5-5, which means that for every unit of electricity that you put in to run the compressor, you get 4.5-5 units of heat out of the heat pump. Water heat pumps can radically improve the energy efficiency and environmental value of any heating system that is driven by primary energy resources such as fuel or power.

It is important to know that these heat pumps are for use during the summer period typically May - September.
