This is my first install ever!
I'm a residential designer and (residential & commercial) contractor. A good friend of mine wanted a airplane hangar built. In an effort on his part to save a little dough, we did the install of the radiant ourselves. Figured I'd see where the cost of install is at. Now I know!
I do have a question on this for those in the know? We have 3000SF with (12) 1/2" dia 250' zones. I cranked the system up to 75 degrees to see that all was running as it should. The max temp I ever get out of the boiler is 83 degrees? The system never made it to 75? What did I do wrong?
