What You Need to Know


My solar domestic hot water system was built mostly from recovered parts, including the (3) 3'x7' panels and the 80 gallon storage tank. A small PV panel powers the anti-freeze loop, which simplifies the other control wiring. I use an external heat exchanger. Nothing fancy, but it keeps making lots of hot water. :)

Other Benefits:

No Fracking Required ;)

Maintenance Requirements:

I've changed the anti-freeze solution 3 times over the years.

Efficiency or Sustainability Improvements:

A drain water heat exchanger saves about 50% of the energy for a typical shower. The system is backed up by a small tankless hot water heater. See separate listing.

My Motivation:

A brighter future!


Just Do It!

Experience with Installer:
