Radiant heat in the floor is what I eventually want to use for heat. When building my shop I put 1000 feet of Pex tubing in the concrete floor with 4 zones. I just haven't hooked it up yet.
My original thoughts were to keep the shop at 45 degrees with the floor heat and utilize a radiant overhead unit for quick warming when I'm actually in the shop.
But, right now it's real hard to justify the cost of heating my shop 24/7 when I don't have enough free time to spend out there.
Although, someday it will happen.
