Does everybody have a room in their modern home they just can’t reasonably heat with normal heating and AC settings? Mine is a third bedroom in the back corner of our beach house. It has served as a sort of junk room for the past many years. However, now both of us are bringing in a foster child and we need that room to be liveable. We raised our little ladies. They turned out to be fine humans and I’m truly content by that. My husband and I decided to provide some love to a kid that could seriously use it. I’m a tad freaked out because this boy has been through a bunch of crap in his short life. Not sure I’ll be able to relate to his but, I’m certain I can love him. So, he’s moving in next week and I gotta get this bedroom warmed up. First, my husband went in and sealed around the window to be sure to close any gaps. I went outside to then pump in some foam insulation around the window frame. We assume there was a draft that was allowing a fine bit of the heating and AC treated air to simply escape. However, he and I also found these room to room ventilators online. They seemed worth a try and were less than a hundred bucks. So, we ordered them and am I ever ecstatic that I did. These little fans fit inside small holes chop in the top of the adjoining rooms shared wall. It didn’t take myself and others all that long to get them put in correctly. But, the difference they make is astonishing. Once they were installed, they automatically flipped on. We left the bedroom for just over half an hour. When we checked on the room, it was as sizzling as the rest of the lake house. So, this young guy will be truly warm and cared for That’s something.
