Confirmed providing heat at -17C
03/23/2026Very energy efficient, gentle warm air with many fan speed, very quiet. No problem to keep 55 sq-m space at the set 21C temperature this winter so far. Come with everything from the picture, plus extra 2M of 12/3 wire for 115V AC line (not shown). High SEER2, 115V, best offer from Costway. Bought a 2nd Unit. A/C feature to check out when the summer comes.
