Pic of the install.......
Temp in the garage, at startup, was 38°. I've got that one set for 55°.
The garage is finished with sheetrock and insulated walls and ceiling.
You can feel just how cold that floor is by the water coming back through the return lines. Also, center return is the longest, as that's the coldest to the touch.
Glycol/water is running through the whole system.
Heat guys said one or two days to feel a substantial difference in the garage.
They're gonna come back out Tues. or Wed. to do a final check and adjust the pressure in the system.
