Easy To Install Water Heater

Very easy to install. The water is consistently hot. I like the LED display for the temperature. It looks fancier than other water heaters. So far no leaks.

We installed this unit under our Kitchen sink. Took less then 2 hours with proper installation items you need. 4 seconds and we hove 125 degree HOT water! Don't be afraid of this install, we waited 5 years, wasted tons of money. We set this a a way lower temp, definitely a perfect shower temp control for dogs and cat! Very cool product!

Works great did a lot of research on tankless hot water heaters to make sure I get full water pressure taking a shower I live in North Central Florida with well water around 72 and I have 40 60 water pressure well pump I'm able to turn up hot water and cold water at full pressure seems like I have more water pressure because it's not going through a hot water heater tank

Firstly, it requires the installation of two 40-amp circuit breakers, and it is recommended to hire a professional electrician for the installation. I placed it in my underground storage room, and it occupies much less space than the traditional water storage system I had before. It comfortably serves our family of four, providing enough hot water for our bathing needs. It can be used in winter, and it only heats up when I need hot water, helping me save a lot on costs.

Well at first it was confusing on the wireing diagram but wintemp straightened it all out and it works like it should thanks R Friedhofer

So far so good on this one. I like that this hot water heater is "instant" (not actually instant in the farthest part of the house, but very quick) and is a SUPER space saving appliance. I actually like just about everything about it so far. If I had to choose something I don't care for it would be the fact that it recommends the use of two 40-amp breakers. That seemed like a large setup for me, but ok...we do what the instructions say. The heater is not hard to install. It has a modern look to it and will hopefully serve us for many years.

This is a tankless hot water heater. It was easy to install. And it works great. The best idea we had was getting this. Thank you
