Answer: 
It is not a 3 phase unit. It is single phase. but it is 3 single phase heating elements, each wired to a 40 amp 240 volt double pole breaker. You will need 3 40 amp double pole breakers and three sets of wire to connect this water heater.

Answer: 
FYI a 240 - 3 phase delta is all 240 volts phase to phase to phase unknown to ground unless u ground a leg, but even then there will not b any 120 unless u center tap one of the three transformers but still no 3- phase 120, and unless u have a commercial device at your house u won't have 3 phase power not even 2 phase just 1 phase 120/240 volt

Answer: 
From what I can tell, each heating element is individually supplied, which means they would be independent of phase. I believe the low voltage microchip inside is probably the only component that actually ties into all three phases, but most likely only monitors the voltage to verify that all three circuits are hooked up. Seems to me that this unit would definitely work.

Answer: 
There are no whole house hot water heaters,tankless or tank type, that run on 120 volts. Only some small, point-of-use, hot water heaters, the type that would be used to heat water for use in a sink, run on 120 volts. What you want, all required 240 volt service, and require two or three double-pole 40 amp circuit breakers, which would require either 4 or 6 spaces available in an at least a 200 amp Read More
There are no whole house hot water heaters,tankless or tank type, that run on 120 volts. Only some small, point-of-use, hot water heaters, the type that would be used to heat water for use in a sink, run on 120 volts. What you want, all required 240 volt service, and require two or three double-pole 40 amp circuit breakers, which would require either 4 or 6 spaces available in an at least a 200 amp breaker box, or to have a sub-panel installed by a licensed electrician if there's not enough space in your breaker box for the required number of breakers. In essence, what you're asking for, doesn't exist. Your other option is a natural gas or propane fueled tankless hot water heater, which are available in indoor and outdoor installation models, and these also require a 120 volt service installation for the controls, and ignition circuits.
I hope my answer is helpful. Good luck.

Answer: 
120 volt is not enough power to heat water fast enough for one shower unless you live in extreme southern Florida or the Caribbean where the incoming water temperature is 77 degrees. Think of 120 volt as the smallest burner on your stove and 240 volt as the largest burner. You wouldn't put a pot of water to make spaghetti on your smallest burner because the amount of heat from that burner is too low. Read More
120 volt is not enough power to heat water fast enough for one shower unless you live in extreme southern Florida or the Caribbean where the incoming water temperature is 77 degrees. Think of 120 volt as the smallest burner on your stove and 240 volt as the largest burner. You wouldn't put a pot of water to make spaghetti on your smallest burner because the amount of heat from that burner is too low. You'd put the pot on your largest burner. Now think of how high you turn the knob on the burner as the kilowatts. The faster you want the water to heat, then the higher you turn the burner up, and the higher the kilowatts of the unit you need. Use the chart to pick the model you need based on your incoming water temperature and your requirement to run 2 showers at the same time. Read Less

Answer: 
This unit is designed to run three showers at one time. There is a lesser unit that operates on two 40 amp 240 v breakers as opposed to three 40 amp 240 volt breakers. I doubt you can find one that will run off of 120 volts that can heat two showers.

Answer: 
You need to go online and select the area of the country in which you live in and decide whether the unit will be suitable for your application. The main factor to consider is your incoming water temperature as this will determine the amount of gallons per minute the water heater can heat.

The highest setting is 140 degrees but the water might not be heated to that temperature if the incoming (outside) water is too cold to begin with. I found that a setting of 125 degrees provides plenty of hot water for me to run 2 showers simultaneously

CUSTOMER REVIEWS

Rated 4.1 out of 5 by 121 reviewers.
Rated 5.0 out of 5.0 by Does exactly what we needed for our home... We live in SW Florida, so our ground water temp was ideal for this model. The KEY to this solution working is having your electrical capacity checked out PRIOR to purchasing. I cannot stress this enough. I fortunately live in a newer home that has 300Amp service, so there was no issues adding this solution into the mix. Not running out of hot water and reducing our electrical bill is a win/win. There are 6 people in my family and this unit keeps up without issue. May 10, 2016
Rated 5.0 out of 5.0 by Recently installed the EcoSmart 27 We haven't gotten the first electric bill, but I can't believe it will cost as much to heat water only as we need it, as it has to keep a 50 gallon propane fired water heater hot all the time whether we use it or not. For $505 it is about the same price as an ordinary water heater, but takes up a fraction of the space and gives us all the hot water we need. We are a family of four in Michigan and have no problem with the water heating up instantly. We had an electrician install it and he was impressed and wants to buy one for his own home. May 3, 2016
Rated 3.0 out of 5.0 by Voltage fluctuation Not a bad unit over all, but beware it will make your CFL and incandescent light bulbs flicker. Within the first month of installing this unit I had 5 incandescent bulbs blow out. My normal house voltage is around 124.3 to 124.6. But when the unit is running it drops to 123 and fluctuates a lot between 123.2 to 123.8 which causes the lights to flicker. The Powerstar unit I had before the eco smart didn't have that issue. April 24, 2016
Rated 5.0 out of 5.0 by Great product We have 5 adults and 3 children in one home..... Never without hot water!! Our water heater has only been installed for 6 weeks so I am waiting on a full months power bill to see how it has been affected. This product so far has delivered all of its promises and exceeded many. I do realize temperature of ground water can be a factor so just for the record, we are in the upstate of S.C..... Love not having to time out showers!!! April 26, 2016
Rated 5.0 out of 5.0 by EXCELLET Output for 3 Baths + Dishwasher and Washer After burning 3 TITANS (purchased locally in Miami) I decided to sunk my cost and go for the best out of the shelf in Home Depot. I had to re do the Water pipe intake and flow from 1/2 Inch to 3/4 to fit into this unit AND place a separate breaker box to load balance my home's 400 Amps into dedicating 125 Amps for this unit to work at max capacity when needed... also rewire 3 AWG instead of the previous 2 - so all in all I spent 2.5-3 X times more over the cost of the unit to make it work properly - BEST INVESTMENT EVER. There is no more light flickering when hot water is flowing and I can have multiple faucets/showers running without compromising water temperature. February 5, 2016
Rated 4.0 out of 5.0 by Product They gave me a 2 week window where it would be delivered in, and it came in 6 days, I was pleasantly surprised. I haven't installed the product yet but thanks for the help ordering it in store and for the extra fast delivery April 26, 2016
Rated 5.0 out of 5.0 by Good buy saves space. Pulling the wires was the hardest part but after that the rest was easy. Oh wait taking the old 80 gallon tank was the second hardest part since I didn't wait for it to cool to drain it. But wiring the tankless in and running the plumbing was easy. I did put in a way to clean it with two other valves and some T-Brass. All in all a two week job for me to do it all even with fixing the dry wall. I will warn others it takes some getting use to NOT mixing cold water in showers since we have it set to 110 in DFW Texas area. No fears of getting scalded, after changing that habit it works great. March 6, 2016
Rated 3.0 out of 5.0 by Ok... But Not What We Hoped The EcoSmart 27 kW product advertisement states that it is capable of supporting two shower heads at 1.5 gpm with an inlet temperature of 47 degrees. Unfortunately this was not the case, based on our experience during the winter months. We live in Northern Virginia and although we have not measured the inlet temperature, both shower heads are rated at 1.5 gpm. During showers, if the second shower head is introduced, the flow has to be cut back by half on the second shower head, even if the temperature on the EcoSmart is set to the maximum setting. Based on our experience, it actually supports 1.5 shower heads as opposed to the 2 it claims. Some thoughts to consider: This was installed by a Master Electrician and both shower heads are rated at 1.5 gpm / each. During the summer months there are no issues with heating the water but winter months pose a challenge. We live just south of Washington DC. April 4, 2016
