Coefficient of performance

The ratio between the heat an appliance produces and the electricity it draws to produce it. A coefficient of 3 means three kilowatt-hours of heat for one kilowatt-hour drawn. The higher it is, the less the appliance consumes — and the less solar surplus it can absorb.

Also known as: COP
