Water Heater 120 v 240
Climate zone 5
Large solar system with battery backup
No gas supply
We are specifying our hot water heater and are looking at the Rheem Proterra Hydrid water heater.
What considerations are there to choose between a 120v and 240v for the electric water heater? Both are available.
(I’m not sure how 120v or 240v affects efficiency, back to back showers, anything else?)
