Just ideas.
If I am now required to explain every minute detail of the down sides to advice I will just stop offering it. I will leave that to the academics sitting in their offices.
I did this for years on the north side of my house and it worked great with no direct sun on the tank. When I had 2 in series it would get the second tank pretty close to the same temp as the air. I probably lost some gain to radiation to the night sky, too, but it was a net gain. I suppose I should note, in order to avoid you explaining the obvious, I only did this while outdoor temperatures were above 55 or 60 F. We have no basement. Info is in my Diary someplace since I actually shared it here long ago.
And, yes, waste heat recovery sounds good but likely not trivial for the non plumbing oriented.

After posting I remembered that there's a building in Calgary that has a heat-exchange system on waste water. Probably city-owned. Just wanted to add the idea to the thread because it's always sounded interesting to me. Steven Fahey[ Parent ]
