On Demand Electric Water Heater sensible?
I’m in the midst of planning my ADU that I intend to self build and try to approach pretty good house standards with it. I live on a small city lot so I am pretty much constrained to my existing garages footprint of ~18’x20′ and one story with a loft. Due to having such limited space I’m trying to figure out the best way to provide hot water for this small studio. Originally I was anticipating using an on demand gas fired water heater, however my city has implemented a moratorium on gas fired appliances for new residential projects so that idea is out.
Since space is at a bit of a premium I’m wondering if an electric on demand water heater would make sense? The unit will have a washer, dishwasher and shower (probably no bathtub) and some solar panels (2-3KW I hope), however the neighbor has a large tree just to the west of the structure so the panels will be heavily shaded the second half of the day.
