I started a thread about how cold your shop gets , now that the temps. are around freezing and below the concrete floor is getting very cold , guessing 32*f . When I built the garage I was thinking of running hot water floor heat but I was talked out of it being the reason I'm not in it everyday so it would have to be left on ( $$$) or take foever to warm up . So I went with oil hot air furance . It will bring the temps up pretty quick ( yea 3.5gph nozzel ! ) but the floor is still like an ice block ! Now I wish if I would have just put the plastic pipe in the floor I might have been able to at least keep the floor sort of warm with solar and just used the furance if it was very cold like it is now . Anybody have floor heat or solar type in their garages ? Al
I would try to insulate the side of pad if you can, but at this late stage ditto on good rug or cardboard will help with your butt being a "heat sink". I do this stuff for a living, and most of my work is fixing others mistakes, how big is building? 3.5 gph is a lot of oil, also is the system ducted, and what about ceiling fans? not to mention control strategy.
