[RE-wrenches] Hot water heater heat pumps

[Dan Fink]

If you are doing a replacement or new, anything 55 gallons and below is
just extra insulation and slightly more efficient heating (and slightly
larger size). Above 55 gallons, the mandate is basically new technology. I
work only off the grid, and heat pump electric uses as much energy as a
full size refrigerator, not an option (unless maybe with a timer as
suggested in this thread, and a large PV system). The gas side of the
mandate is condensing heaters that recover waste flue heat; we already have
those on the on-demand side. Hopefully the SWAT teams can do double duty
and seize toilets that use too many gallons per flush also.
