They are marked

Had 1300 ft of pipe, there is 1250 there, I have a six loop manifold, I could tighten the middle up and add a short loop.

I would agree with you guys about the distance between line but since it is in a garage and no one is walking on it with bare feet I don't think anyone will notice. On another note check out the program LoopCAD. It has a 30 day full program trial. Awesome program!

I would agree and being that is closer to the center it should be fine.

So did you find a leak?

[coolidge]

Haven't looked yet.

Interesting, by looking at the insulation on the walls your vapor barrier is sprayed on ?

[coolidge]

thats 2" of closed cell foam sprayed too the original concrete. I don't know why i put that insulation on the walls, there is insulation on the outside already.

Better to ponder why you did it than wishing you did it.

[coolidge]

My plan is to strap that Insulation and put up some plywood, on walls that don't have shelving or benches anyway.

Did you leave a spot for the supply/return from your OWB to come through the floor, or any other penetrations you need?

Is your garage a pressurized closed system separate from the OWB system? If it isn't, how are you tempering the water from the OWB?   

[coolidge]

I am leaving the OWB lines where they are( orange pipe).
Running an open system from boiler, there is a mixing valve down in that mess somewhere.

Would it be beneficial to pressurize the system?

[E Yoder]

I've never pressurized a floor, just mixed and dumped the furnace water right into the floor loops. Used mixing valve or injection mixed on a big slab.

[hondaracer2oo4]

Seems like it would be hard to balance flow , keep a loop from getting air bound and also what do you do if you want to stop heating te floor in the cold months as far as freezing goes?

[mlappin]

If you want to run glycol then just need a plate exchanger, my snow melt isn’t pressurized and works just fine.

I have mentioned before and I'll do it again Honda, Eldon is in Va, he can get away with a lot of stuff down there that folks up here would nail your private parts to a stump and push you over backwards for doing.
