Comments about EX55T Thermostatic Electric Tankless Water Heater:

I used this product to preheat kitchen sink water until my Noritz gas tank less unit caught up. The only issue that I did not like was the temperature adjustment control knob. It should have been larger in diameter and had some sort of markings on it. The unit would had been easier to adjust the temperature if the control knob had markings on it so when you turned it you could have a reference as to how far you had turned the knob in reference to how much the temperature went up and down.

      I'm not sure absolutely what it is. I bought it to boost the hot water line
      to my dishwasher. Before I installed it, I was only getting about 90 deg
      water to it. Afterwards I got it up to about 120 deg.
