Amen. Mount it in the EV so you can flip it around. I have a window AC in a bathroom hole-in-the-wall so that I can slide it out and reverse it in winter. It provides plenty of heat when the outside is above 40. It provides as much heat as the 1500W electric heater but only draws 5 amps. (Though it is noiser in the winter)... I used to have a 10,000 BTU window AC unit mounted under the floor of our center hallway. Instead of 10,000 BTU of cooling, I got 30,000 BTU of heat up into the room (while cooling the basement in winter). But the basement never got below 60, since it has a huge heat source (the ground, laundry and waste heat from the oil boiler). This AC (heat pump) would come on by timer at 9 PM (when the electricity dropped to 2 cents/kWh) and maintain the whole house at temperarure through the night Keeping the oil thermostat from kicking back on. It was easy to find old AC units during appliance collection day on the side of the street. Over the years, I must have picked up a dozen AC units and EVERY one of them only had one problem, the same problem, the fan motor was gunked up and never oiled (or a few had bad thermostats). A little oil most often restored the fans to normal operation. Don't need it anymore. Installed a geothermal system and got rid of Oil heat!
