I just had installed three Mitsubishi RW25 heat pumps, latest tech which works with efficiency factor of two in -30 C (-22 F), and still produce their nominal heating power of almost 4 kW in -20 C. I live in southern Finland so we rarely even experience such low temperatures. Very good ROI. Independent test in Finnish: https://www.scanoffice.fi/wp-content/uploads/sites/11/2022/0... |
