What is the best solar water heating system?

Geri Rhodes July 6, 2018Updated: July 30, 2020

I live in NM where the temperature gets below freezing in winter and around 100 degrees in summer.  In my small mechanical room I have a propane boiler and an indirect-fired WH which I use for my radiant floor and hot water.  I also have a heat pump minisplit, and I have PV electricity.  Which would be better (more sustainable) for me for heating water--a system such as the Vitosol that works with my boiler but kicks in first; a Vitosol with electric backup; or an hybrid electric heat pump HWH powered by my PV?  I notice you also write about the outdoor compressor that goes with the heat pump, the SANCO2, which I'm also considering.  Thank you for any advice you can give me.

Thank you.  I'll look into the DC option and look forward to any updates from you.
