The only ones I have installed are the add-on units for existing water heaters. From customer feedback they seem to work well. Recovery is slower than straight electric heating if two or three showers are in a row. Thinking since my water heater is right next to my coal stove I should get pretty good efficiency.
The one advantage of both AirTap units are that you can duct them into existing ductwork, a floor register, or outside (in the winter).
I used to install air taps, not real good, the parent company is now importing a one piece design, exactly the same as the ones I imported from last year. a much better unit, check out airgenerate. it should show newest units.
