The manufacturer's literature should supply the two a COP to explain performance in heating mode, and an EER or SEER to describe performance in cooling mode. Real performance may differ, however, and depends upon many variables which include installation aspects, temperature variances, site elevation, and maintenance.

A further issue to remember is the fact HPWHs Have got a quite slow recovery price—I think ours recovers at a price of about eight gallons for each hour.

That's, a person joule of electrical energy will induce a resistance heater to provide only one joule of useful heat, while under suitable problems, one joule of electrical energy may cause a heat pump to maneuver three or 4 joules of heat from the cooler spot to a warmer location.
