Rated 3.7 out of 5 by 6 reviewers.
Rated 4.0 out of 5.0 by Works in temporary building Had to run heavier 10 gauge wire. Low volume, but enough to wash dishes. June 4, 2013
Rated 4.0 out of 5.0 by Point of Use Hot Water Heater Very good for my particular needs. Used for a sink in my work shop. Only downside is the lack of a temperature control. Temp is adjusted by adjusting the outlet valve. Not a deal breaker for me. The plus side is that I'm not constantly heating a storage tank. October 21, 2014
Rated 4.0 out of 5.0 by Good product Small and easy to fit in tight spaces. Simple installation. April 7, 2015
Rated 1.0 out of 5.0 by Returning As long as you want a dribble of water it stays really hot, once you turn up the flow it goes cold. It should work well if you were using it with a hot water tank but not by its self. Returning. February 11, 2014
Rated 5.0 out of 5.0 by Slick Little Heater This has to be the smallest little insta hot water heater I have seen, Very sceptical at first as far as performance... works like a dream.. instant hot water , takes up very little space , runs of a single pole 20 amp breaker... very happy with its performance May 13, 2015
Rated 4.0 out of 5.0 by Single point tankless water heater The single point tankless hot water heater was simple to install. I think it will do the job for me. April 22, 2015
