This smart technology heater is configured for climates where incoming water temperature can reach as low as 37° F. This model is well suited for homes in the northern U.S. and Canada, as well as in the southern U.S. that have large Roman-style or Jacuzzi tubs and generally more demanding water usage needs.

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.

The major question to ask in this instance is what is the inlet water temperature to your water heater? Using the chart on the page showing the water heater will indicate the temperature rise each water heater will accomplish with a specific flow rate. From there, I believe you can anticipate a maximum flow of about 3gpm given normal household activity. This estimate anticipates that you don't shower while the dishwasher or clothes washer are running with the clothes washer on hot wash. If that is not the case additional flow will be required and therefore a larger water heater will be needed. It is important to remember this water heater only turns on the number of internal heaters necessary to heat the water to the desired temperature. This saves energy when full demand is not necessary.

Answer: 
The answer depends more on the temperature of your incoming cold water and how many fixtures must have hot water at the same time than what size tank you now have. Use the chart to determine the right size unit.

Rated 4.1 out of 5 by 30 reviewers.
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 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 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
Rated 5.0 out of 5.0 by Couldn't be happier! We have an approx 2,000 sq ft home. 4 member family. We never run out of hot water anymore since switching to this water heater. I was skeptical at first, but am so happy we went forward with the switch! March 29, 2016
Rated 5.0 out of 5.0 by Extremely satisfied with this product I bought this product new years eve and received it within days. I installed it myself in 5 hours only because I had to run new wires for the breakers I added. Easy installation other than that. The performance so far has exceeded my expectations by far. I can run 2 showers and do dishes without the hot water ever slowing down. My power bill should plunge on the next bill. Also, the amount of space I have gained by eliminating the large tank has created a new broom closet. Happy wife, happy life. I would recommend this product to anyone thinking about going tankless. Extremely happy customer here. January 16, 2016
Rated 5.0 out of 5.0 by Glad I made the change Very small foot print compared to the 53 gal hot water heater that was there. Saving me time not having to wait for the water to heat up and also saving me $$ because it only comes on when needed. June 17, 2015
Rated 2.0 out of 5.0 by Disappointing performance First on the installation aspect easy to install but not engineered very well. Watch out when tightening your connections they are to close to main box to get wrenches on the nuts to tighten. screws for the cover are in the same place as connecting valves, hard to get to. Hook-up is easy but directions say do not use Teflon, weld or paste, they leak if you use the recommended inlet and outlet valves for $75.00. I live in NEast my inlet water temp is low, do not recommend for a 3bed 2 bath up here hot water is not sustainable with this unit. I have only 3 water outlets in a small ranch and cannot run sink and washing machine at the same time for more than 30 seconds. I turned the waterflow on inlet to 1/2 and still cannot take shower and wash dishes with hot water. Very disappointing. Please insure to read the small print on the warranty. Must be installed by LICENSED plumber and electrician or not valid according to the 800 number. March 30, 2015
