Well we received the final bill for the shop build this morning (only charged me $120 extra to fix the run in with the tractor). He still has to finish the cabinet around the heater manifold, and paint it, then he will be done. I still have a ton of stuff to move in, but have been waiting on him to complete his part of it first. He plumbed my pump for the heater drain Saturday and it seems to be working good. I heard it kick on with the heater when I was out there yesterday. I'll try to get some pics of it if I think of it.
One thing I found funny talking to him this morning, he is going to change his tank water heater in his shop to an on demand like he installed in my shop. He is really impressed in how well it works.
I believe when I posted pics of the insulation going in someone made a comment about moisture control. I kind of blew it off, mostly because I'm ignorant, and also because I didn't think it would be an issue. Never been in a shop that had any kind of issue with being sealed up so good the moisture couldn't figure out how to get out. I have now! I washed my truck (with warm water) on Friday evening and it immediately turned into a rain forest inside the shop. I kinda chalked that up as "well that's me introducing moisture so I'm going to have to pay attention to that". I wasn't in the shop Sat or Sun (except to park the truck, and I hung out for about 10 min while the heater cycled), so I would have thought it had time to dry out. Fast forward to last night/this morning-I parked my company truck in there last night around 7:00 with very little snow and ice on it. Floor was dry this morning, but all the windows were covered in moisture, and when I raised the garage door to back out water ran out of the door. I have a small dehumidifier that I am going to throw out there and see if it helps any. I've thought about an exhaust fan vented to the outside, but it's going to have to move a ton of air. I'm interested to hear others thoughts on the issue. Will it stabilize as the concrete continues to warm? Right now I would say my concrete is around 75% warm. What I mean by that is, the center of my concrete slab is around 75degrees, but the outside is still 60 degrees, so I know that it's still not 100% warmed up. Thoughts?
