Today I had an Anderson full-view storm door with interchangeable bug screen and glass door installed so I can have the front door open and get some fresh air, since only the bathroom and loft windows open and the other ones are stationary. I mentioned to the guy installing the door that the only heating source was a wall heater in the bathroom. He pointed to the Daikin mini-split and said: Doesn't that have a heating coil? They usually do. Check the manual.
Turns out he is right. All these past few months, I've been cold at night thinking the only heat source was a wall unit in the bathroom. I've never had a mini-split and always have had central air. I am warm and comfortable while I type this post
