Does this require 3 breakers?

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?

Is this what we need to get instant hot water when the hot water heater is a long way away? Does this stop heating when the hot water finally arrives from the basement?
Asked by: El
This is in place of a hot water heater. I installed one in a rental that I have. Works great except for large whirlpool tub. Can’t open faucet wide open to get good hot water. I will never install another hot water tank. Will use these only if enough Electric in the panel.

24 kW Self-Modulating 4.6 GPM Electric Tankless Water Heater is rated 4.4 out of 5 by 63.
Rated 5 out of 5 by from Tankless is the way to go with a large family After having success at my previous home with a different brand of tankless hot water heater, there is no way I would ever go back to a traditional tank for a large family. I have 8 children and a normal tank will not sustain hot water for more than a couple of showers and then you have to wait for hot water to be produced. This unit has enough throughput for sustained hot water as long as it is needed running thru at least 2 faucets at a time. We can use both bathrooms for showers or run one and laundry, etc. Someone with basic abilities to install electrical lines and water supply will have no issues performing the work themselves. I have had to contact support twice for assistance. ECOSmart support personnel have never asked whether or not this was installed by a licensed contractor or not. My only issues were the "flywheel" being stuck just after installation due to residue in the line shortly after installation and a blown fuse. Both repairs were completed by myself and totalled less than $1.

Rated 5 out of 5 by from It does what I hoped for My last house had a large gas tank-less unit so I knew what I was getting into. I know the electric versions do not have the BTUs the gas do but the new house is electric only. I went with the 24 KW unit but after install wish I had gone with the 27 KW. I called EcoSmart tech support and found out that the only difference is the heating elements. I was going to buy the three 9000 watt elements but they said they would send them for free if I paid the shipping! What a deal and what a good company. I installed the elements when they arrived only to realize I did not have three 8000's but two 9000's and one 5500 element. I was 500 shy of the 24 KW I bought but they had already corrected it so I don't care. When you install look at the top of the elements and make sure you have what you should have. Even if you don't EcoSmart's support will take care of you. Now we have full pressure super hot water at our multi-head shower all day long. I still need to play around with the temperature on the unit for the best efficient setting but that is easy. Just make sure you use the correct size wire and breakers and the rest is cake to install.

Rated 1 out of 5 by from Sorry charlie.... not up to snuff I recently installed an ECO 24 in our new home with hopes of costs savings and simpler "leak resistant" solution to hot water. We live in the pacific northwest with incoming water temperature at 48 degrees. We chose not use a gas unit because of the price of propane vs electricity where I live. The unit seems well made and relatively easy to install in a new home. The bad news is that the hottest water I am able to achieve is 90 degrees... hmmm. This is one sink running 1/2 open, maybe about 2 gpm. Forget about the shower and two faucets I am supposed to be able to run. I spent an hour on the phone with a tech and we confirmed that even when all 3 elements were at full tilt, the best temperature rise I am able to achieve is 35, maybe 40 degrees, with a resulting luke-warm "hot" water. I just don't get how anyone can get reasonable results with these units in a whole-house scenario. Now I have no choice but to either abandon the unit altogether, or merge it with a conventional tank unit working as a pre-heater. I am really disappointed.

I purchased this heater to replace one similar to it (an older model) which stopped working. Since the wiring and water connections were there already, installation was really easy. In less than an hour, I had hot water back. I installed a 2 gallon per minute flow regulator at the outlet connection to maintain a constant flow rate through the heater, which helps it to maintain temperature more accurately. In northern areas, the incoming water temp is colder, so the flow rate should be decreased accordingly to assure adequate output temperature. In Maine, 2 gal per min is just about right. The flow regulator should always be installed at the hot water outlet of the heater.

Rated 2 out of 5 by from 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.

Electrical had to run some wire but being an electrician for forty five years , it was no problem. Did it all in just a few hours. Probably voided my warranty ,by doing it myself, but couldn't see paying someone to do what I've always done. My wife did help pull the wire. Turned the water on let it run for about 3 minutes to remove air from water lines then turned on the power ,set to 110 degrees and hot water . Never a problem , just set it and forget it. Took up so little space and looked really neat my wife wanted to take pictures and show everyone. I would encourage anyone to get one of these Eco Smart heaters when replacing a tank heater.
