Opinions on the Heatworks Model 3 no-elements water heater?
Any insights into how well this Heatworks Model 3 water heater, “The world’s only water heater powered by Ohmic Array Technology instead of metal heating elements,” should work? It’s basically a more efficient tankless without elements:
My area has extremely hard water. I just dug two gallons of limescale flakes out out of the bottom of my water heater tank after they destroyed the lower element. I replaced both elements with the low-watt-density type that are supposed to produce less scale, but a water heater that produces no scale at all, is more efficient, and is smaller has a lot of appeal. A heat-pump water heater shouldn’t produce scale either, but I would have to put it in a utility room (no basement or garage), where it would cool the house during heating season (and during cooling season, on the plus side), depending on how and when I might duct it to the outdoors.
