I got to go out and fix a small drip leak today, so I took some pictures and thought I would throw them up here.We finished this job last October, and made it through the winter without a problem, the homeowners love it. House is a 10,000 sq foot (including basement) 2 story. 12 zones (including a glycol loop for the garage) served by a 200,000 btu NTI boiler. 3-3ton Carrier condensers/gas furnaces each with 2 zones. It was a good job, I really enjoy doing bigger fancy systems like this. Not to many people want to fork out this kind of money Although I wish the general and homeowner would have been more organized and we could have incorporated the two 50 gallon water heaters into the system.
On the left is a NTI 399,000 btu boiler for the driveway snow-melt system.
We laid over 22,000 feet of pex on this job! The only problem we had was other trades puncturing the flex. I photographed every inch of pex, but they still managed to hit it 3 times, two were pretty easy, but the flooring guy sunk a nail through and turned into a disaster. I'll post some pictures if I can find them. We got paid to go back and repair it, so everything was good.
