Here are some pictures of the solar hot water system. This system, so far, is comprised of approximately 800 feet of PEX-Al-PEX tubing located beneath the roofing on the west side of the house. This tubing will eventually be filled with a glycol solution (to prevent freezing) and passed through a heat exchanger to heat domestic hot water.

First we had to take the roofing off. Since we were taking off some of the roofing for the mason to construct the chimney, we thought we would do the hot water system at the same time. My good friend lent us his bucket truck, which helped immensely!	The tubing in place. It took me most of a day to get the tubing up and placed. If it had not been so hot, I could have done it in about four hours. If you try this, start from the top down!
A view of the tubing near the chimney. Note where the tubing enters the house. I cut a slot through the panel, then foamed it after the tubing was in place.	Using my temperature data logger, I measured the temps under the roof for a few days. The highest temperature we recorded was about 162 degrees F. Click on the image for a closer look.
