I went that route in S&B,,,,, never again.
You can not just run warm water at a lavatory, either way too hot, or running water wide open on both taps because the heater requires a specific flow in gpm to turn on, once its on, its full hot, there is no mid point, so you have run large amounts of cold to balance it.
For us at home, in the winter we run the hot only, to get a lukewarm shower. 45 degree water in, needs a 50-55 degree rise to be warm so the 13200 watt unit can only meet that at a .6 gpm flow.
In the summer, 65-70 degree water in, we must run the full 1.8 gpm at the heater and then add cold to keep from having the systems safeties cycle the unit off and on to avoid scalding. Which if that happens, you get a cycle of full hot, then all cold, then all hot.
I cant see it ever being a good idea in any system trying to conserve water. We have learned to use it at home, and we dont really have a good place for a conventional unit, otherwise I would have tossed it.
