If the Vapor aspect works well then this might make air source heat pumps tenable in cold countries. The current crop here in the UK are costing home owners a fortune as the 3-4 kw multiplier drops to 1 below 0degC or so and hearing becomes horrifically expensive. I know a chap who was paying £1,200 a month to hear is home at the worst of this winters cold and the energy price jumps we have here.
- pappn 4y agoFYI, air-to-air heat pumps are very popular in Norway. There are models that have >2 COP in -15 C, for instance Toshiba Daiseikai 9S at 2.35 at -15C, and >5 at +7C.
- IanCal 4y agoThat doesn't sound right. They should be above 1 for much lower temperatures.
