The expression that heat rises never really made sense to me.
I know the reason is that I always lived in a 1 story house.
I did not unquestionably get that heat rose until I bought my first beach home that had a apartment dining room. There was just 1 floor, however you could go up a ladder plus be in a little dining room/apartment hidey hole. I thought the little dining room was super cute plus immediately set up my stuff there. It was prefer a secret dining room plus I liked how it was tucked away in a corner, then well, 1 Winter time season changed my opinion. I ran my furnace method to the maximum setting; No matter what I did my home felt icy cold. I ended up setting my furnace to around 73 degrees in order to assume somewhat warm. Then every night I would sweat buckets in my little high rise dining room. I could not have a single sheet on me, any clothing plus would still sweat to death, but since the dining room was just a little floor with a mattress on it, I could not hook up a cooling system. I also did not want to run an cooling system while I had the furnace going. It was horrible sleeping up there. I finally had to supply up my little hidden dining room. I removed that loft, upper floor plus just made the home 1 story. This way when the heat rose, the whole home felt the same to me. Ideally, having the heat not rise would be best. But, I am just ecstatic that I no longer sweat buckets at night.
