We've been in the new place for a year but never got the heat hooked up in the woodshop. Well, now it's done! It's a 40,000 btu on demand NG water heater (rated for hydronic heat too). It's done and putting heat into the floor as we speak. Water temp is 140 going in and was 82 coming back when I checked it 30 minutes ago. It's been running about 3 hours now. I have about 750 ft of 1/2 inch pex tubing in the floor, about 950 sq feet and a generous 5.5 to 6 inches of concrete with 2 inch foam below it. Superior walls with 2.5 inches of foam. The shop is full of equipment and wood so there is a huge amount of mass that needs to be heated. I'm expected it will take all night to bring it up to 55 or 60 degrees.
I may store some of my shooting supplies there so I don't have so much in my basement. I'm thinking maybe my extra primers and powder. My lead supply is already there (something else to heat up...).
Aside from that, I'm ready to get some wood projects done for my very patient wife!
I guess I need to get some pictures posted. Maybe tomorrow...
