I am in the process of building a 24000 gal gunite pool. My Solar Contractor wants to place the collectors on my south facing second story roof. The problem, my pool is on the north east side of the house. That means a long run over the roof and over the ridge for all the water.
The following drawing shows the problem.
I don't want all the roof penetrations or all the pipe on the roof. I don't want all the issues with crossing the ridge-line (difficulty draining) etc.
Therefore I am proposing running the fed and solar returns to the Equipment Pad in a trench.
As shown below:
Will I have any heat left when I get back to the pool? The run is about 120 feet.
Can I insulate the return in the trench? Will that help?
Is going over the ridge line really a problem?
Any expertise, advice or comments would be appreciated.
