Residential solar thermal no longer makes any kind of economic sense. These existing mandates only show how government regulations can serve to ossify bad practices and harm innovation.

- jws 8y agoNot a citation, but when I last looked at it for a cabin, the plumbing costs, pumps, and extra stuff required in addition to the normal heater drove the cost so high that it was just cheaper to add more PV panels, which have been coming down because they are made in great volume. Someplace without freezing weather, or someone who might just say “too cloudy too long, no warm shower today” might have a different calculus.
- beagle3 8y agoAs far as sun goes, Israel is comparable to California, and all data I was able to find is along the lines of "8% less energy production required, 3-5 years ROI". To me that does make economic sense, both at the state level and at the individual level; why do you call it a "bad practice"?. AFAIK, the laws do allow PV panels instead of solar thermal. I'm not aware of any innovation harmed by such a mandate in either Israel or Portugal. Do you?
