Works just as advertised and was super easy to install. Love it.

I’ve had it install for about 2 weeks. Very simple install. Didn’t even read the instructions. Works amazing! Added a water softener and a on demand water heater.

It seems to work very well. We have plenty of hot water even to our upstairs bathroom. As we live in up state NY with cool ground water. Still has no problem. Actually we turned it way down Because it was coming out very hot. It's been in use for around 3 weeks. So far so good.
