It will work the same way the heat pump heating system in my house works. It will just blow cold air. My daughter visited me recently and said it’s just like an air conditioner blowing cold air on you all the time. Yes, it is I said standing there dressed in flannel Pj bottoms, a t-shirt, a turtleneck sweater, a hoodie, and my bathrobe while also wearing 2 pairs of heavy socks.
Perfect visual description.
You shoulda stepped outside to warm up. 😆
My heat pump blows only coolish air, too, but the thermostat says the house is holding temperature in the Winter. I think the two are in cahoots!
I have gotten very used to wearing 2 pairs of fleecy pants and a hat in the winter in the house. I can get out of bed (stepping right into slippers) and walk through the house relatively comfortably at night. I do this in mid-Winter to light the kerosene lamps that keep the heat pump from running all night.
When I lived in Maryland, my home had a relatively efficient heat pump, but on really cold nights, it still needed an emergency heat element to get the job done. That failed once, and the temperature in the home dropped into the 60s and then the 50s.
Heat pumps also tend to freeze in cold temperatures and aren’t easy to fix for many reasons, including lack of available parts, which can take days to week to come in stock. Crazy people aka politicians & activists want to control and make miserable everybody’s life.
