- Heat pumps are two to three times more efficient than fossil fuel alternatives in places that reach up to -10C, while under colder climates (up to -30C) they are 1.5 to two times more efficient. https://www.cell.com/joule/fulltext/S2542-4351(23)00351-3 642 comments science
- Coming in from the cold: Heat pump efficiency at low temperatures | In extreme cold climates data have shown that heat pumps can provide heat at efficiencies up to double that of resistive heating https://www.cell.com/joule/fulltext/S2542-4351(23)00351-3 62 comments science
