The big positive to the heated floor is far less dust in the air as most shops have some form of forced hot air heating. You also have large masses being heated not trying to heat the air to heat the masses. Also most buildings have cold spots. Cold air drops to the floor and I would much rather lay on the 75-85 degree floor. We can wash cars in our shop and the floor is dry in an hour or less. We also use humidity sensitive switches to control 2 smaller exhaust fans to remove moisture from the shop. My lungs and raw steel appreciate this. I use a thermal probe vs wall thermostat set on the slab during the summer to keep the slab above 67-69 degrees. This greatly reduces the condensation on the floor when we open the door. Warm wet air and a cold slab are booth slippery and not good for controlling building humidity. Let's see some more pictures of the shop.....
an organized, heated well lit garage would be nice. I'm in New England and I work outside year round, and honestly i don't usually mind the snow/rain/blazing heat or cold. I do have a decent sized garage but truthfully I'm too lazy to take the time to move the toy cars out, set up the heaters and get out the work lights. Not that i would'nt want a dream garage with all the amenities but putting 3 kids through college put a serious damper on luxuries. The daylight outdoors is optimum for wrenching work and i like having space to move and except for a few really awful weather days I really don't mind working outside and oddly prefer it.
I just have a 2.5 car detached garage, people ask why don't I heat it, #1 is Im not paying to keep cars comfortable, and #2, unless you have some sort of humidity control, you'd have to have enough heat to burn off the condensation that starts when some things are warm, while others are still cold.
Is the back side open? Seems like a loading dock. I luv cynder blocks. If you ran refrigerant through your floor pipes you could make an ice rink.
Garage sits on a hill.. 6 foot elevation change from front to rear. Hence floor elevation change. Roof line stays the same. 9 foot in front 1/3 remaining had 15 foot for a lift
So instead of choping off the top of your little hill, or making it bigger. You just took a notch out and cynder block retaining walled it. Are you gonna divide it all the way up. Wall up the middle?
Not to be picky, but I've had issues with block retaining walls. Did you fill the block and rebar every hole?
