Which heat pump reaches that kind of efficiency when the temperature differential is so high?
- kwhitefoot 5y agoNone as far as I can tell. Some people I know here in Norway turn off the heat pump when the outside temperature is below -25°C, but those pumps were installed some years ago. New ones do have a significant gain at that temperature. For instance this Samsung Nordic Home: https://www.elkjop.no/product/hjem-og-husholdning/oppvarming/varmepumpe/215947/samsung-nordic-home-25-varmepumpe-nordichome25 https://www.elkjop.no/product/hjem-og-husholdning/oppvarming...
- Epa095 5y agoGood point, I did not think about the fact that the effeciency went down. But it seems to me (as a noob) that modern heat pumps specialising in low temperature conditions still can get around 2.5 at -25°, which gives you more than 10kWh of heating at 5kW, which is quite a lot.
