[Greenbuilding] Heat pump HWS

[Jake jakaitis]

Thank you gentlemen for your thoughts. My understanding from this
Thread is to provide solar thermal panels as the primary heating source for the hot water storage tank. PV panels are added to supplement the solar thermal when needed.  My conclusion is that
For ideal off grid energy efficiency is that hot water usage should be timed for optimal (least energy demand).

My work with energy efficient upgrades found that homeowner habits
Must be managed to obtain the benefits of any work we do. Long hot showers need to be managed too ... Admittedly this is my personal habit that I am working on to make more efficient.
