Hedonic adaptation really is something. I have been deeply trying to appreciate these modern marvels more and more, but it's hard. A hot shower, air almost 50 degrees cooler than the outside air coming out of my vents, communicating instantly thousands of miles away, it's all so easy to just forget and take for granted
Not trying to shame you but...50 degrees? Do you live in Phoenix and keep your home at 60 degrees?
So to keep your home at 70, you need exit temperature to be 50-55F.
seems like it might be lower or higher, depending on humidity.
