I got an idea...

Well I have a heater in the room as well, but I'm currently living at my girlfriends house, and her parents kind of strict about the electric. I told them to look at their previous bills and whatever the new difference is with the heater plugged in I will pay so I turned that baby up. I've been able to keep it at 75ish now. But I was thinking that maybe if I build a rack, like a CB70 plywood or melamine type deal, I'm sure with the temps of the room up and the tubs being surrounded I thinnk it will help the ambient go up. I mean cuz right now the excess heat that isn't being used goes right into the room, if it's in the rack each level will retain that excess heat and make it slightly warmer or am I completely wrong? I have never used a rack before so I don't know what to expect.
