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?

24 kW Self-Modulating 4.6 GPM Electric Tankless Water Heater is rated 4.3 out of 5 by 40.

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.

Rated 5 out of 5 by from Hot Water On Demand We recently replaced a 23 year old traditional hot water heater with the EcoSmart unit. We love the efficiency of the unit as it is only on when the demand for hot water is present. We were able to quickly adjust the water temp for top efficiency using only hot water heated to usable temperature rather than overheating then mixing cold water to the desired temperature. I highly recommend this system.

Rated 4 out of 5 by from Made the right decision. The electric tankless water heater takes 1/3 of the space of the gas version, don't have to have the venting of gas. The amp pull has required additional wiring - 3/35 amp breakers. Installation was very easy. I could have never used a conventional water heater due to space restrictions.

Rated 5 out of 5 by from 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!

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from Work as advertised I manage 40 unit condo complex and I have installed (will need hire licensed electrician and plumber) about 10 different tankless water heater units. And this one works as advertised. Simple and intuitive installation once the licensed electrician allocate enough power to the unit. By the time the electrician and plumber's cost are added the total will probably about 2x or 3x the cost of regular water heater. HOWEVER, the saving in electricity and disaster prevention (like when conventional water heater bust and cause flooding) is well worth the project. Because the unit is tankless there is no worry about flooding when it stops working.

Rated 5 out of 5 by from best product We purchased this electric water heater in 20010 from the manufacturer. This is a US made product. Excellent low cost and low electric consumption . It does not use all the modulators at one time, only when it is absolutely necessary. No more hot water heater leaks. Use on demand product. I recommend the bladder retainer that the manufacturer sells. Set your water temperature for your taste without mixing. Did have minor problem with it going out . The modulator line burnt out. But the manufacture immediately sent out the parts that needed replacing with no problems. They have the best customer service I have had in years.
