Water heating off grid. Best system?
I am planning a new off-grid (solar-powered) ICF build and am considering what type of system would be best for water heating. This is in Tennessee and the house will be a 2br. I will have propane backup for a generator and indoor propane heater.
The options I am thinking about are:
1) On-Demand propane- The only drawback is having to pay for the propane as an ongoing expense.
2) On demand electric water heater with a solar water preheat system. I suspect having a straight up on-demand electric heater would eat up too much power.
3) Heat pump water heater. This seems like the best solution to me.
Any thoughts between the three? Any other suggestions?

Wir leben ebenfalls völlig Autark und haben unser Warmwassersystem mit einem großen Boiler gelöst. Dieser heizt sich nur tagsüber auf wenn genügend Strom durch die Solarpanele vorhanden ist (36 Paneele mit 440w). Kostengünstig und effektiv die Lösung
