From what I see it requires 3 breakers. I would be replacing a existing water heater. Would I have to run new wire and add another breaker?

Answer: 
Yes, it does require 3 breakers, at least the mid to higher level models do. The one we installed requires 3 power input wires - so 3 breakers are a must.

Answer: 
All tankless heaters heat water a certain number of degrees above incoming water temperature. Its' satisfactory operation depends on incoming water temperature. Once that is known, the flow chart will indicate how much flow can be attained at that incoming temperature. You can then determine if this unit will operate satisfactorily for your application.

Answer: 
Ralph The key is how much water you are going to use at the same time. If you want to only use 1 faucet to wash your hands, and nothing else at that very same moment, the lowest one will work. That is not how most of us use water. I recommend buying the 24Kw if you give me the 18 or 24 choice. I say this because you will likely NEVER use more water than this system can produce.

This unit is not rated for outdoor use. 240 volts at 100 Amps is a lot of kick for something not rain proof and the high voltage could become hazardous since it is not insulated from rain etc.

Rated 4.2 out of 5 by 35 reviewers.
Rated 5.0 out of 5.0 by Eco Smart 24kw Expanded our kitchen. It had an old tank electric water heater in it and we added a small laundry room off the kitchen. We removed the old water heater and rerouted the water lines and installed the Eco Smart 24. There are two of us and it is more then sufficient for us. Very pleased. We keep it at 112 degrees. It is nice to just get in the shower turn on the hot water and dont need any cold. Highly recommend. I did the electrical and had a plumber to do the water lines. Pretty simple actually. August 5, 2016
Rated 5.0 out of 5.0 by Great money saver Sale price made this very affordable. Could not install myself because I needed breakers installed. However, since I have solar electric it is saving me big time on my gas bill. Also freed up space in my garage for additional shelving and storage. July 26, 2016
Rated 5.0 out of 5.0 by WAY BETTER THAN A TANK HEATER I received the unit, bought 100 bucks worth of electrical and plumbing supplies, and installed it myself in a few hours. Instantly was able to take a hot shower. I even installed it into a 100amp service. Works great. I might have voided the warranty by doing it myself, but I can buy 2 new units with the money I saved not hiring an electrician and plumber. August 5, 2016
Rated 5.0 out of 5.0 by Great product We are on a well and our hot water smelled from the hat water heater we installed tankless water heater and no more smell. Works great. December 22, 2015
Rated 5.0 out of 5.0 by Wish I'd found this years ago Finally a tank-less hot water heater. The website says it should last 3 times longer than the old tank type heaters. This unit will be professionally installed by plumber, since I am not familiar with this type of unit just yet. June 23, 2016
Rated 5.0 out of 5.0 by Eco tankless hot water heater Nice item but was unable to get home depot to install it. Got tired of talking to them over a 3 week period, lots of promises but no action. Finally contacted local Professionals on Monday and we were up and running the same day. This unit is great, and compact, lots of hot water when needed. highly recommended . May 17, 2016
Rated 5.0 out of 5.0 by Great investment It works great I should have got1 years ago. I would recommend thatpeople buy this unit over a regular hot water heater June 7, 2016
Rated 5.0 out of 5.0 by Effective Water Use I was skeptical at first but this was a great buy! I put a unit in each of my rental properties creating more storage on site for tenants. May 29, 2016
