Questions & Answers

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?
Asked by: Scott
No! these answers are for a larger unit; Not for 8kW. This only requires 1- 40 amp double pole breaker ( 2 wires)

Heater doesn't turn on at all - doesn't show temperature. Should this only turn on when the heater detects the water

Flow?
Asked by: ROBIN
The 18 KW tankless water heater should display temperature when the dial/knob is turned. The display should remain on when there is water flow passing through the system. Please contact our technical support at 877-474-6473 for troubleshooting assistance. Thank you.

Customer Reviews

8 kW Self-Modulating 1.55 GPM Electric Tankless Water Heater is rated 4.1 out of 5 by 703.

My previous Eco18s failed for the same reason. The 1st stage heating elements burn out. The first unit's heating element lasted 2.5 years. The second unit's heating element lasted almost 2 years. Researching Eco Smarts reviews on the various sites selling their tankless water heaters show that their heating elements burning out within 2 years is a common problem. My second unit's burned out heating element will not come out of the manifold preventing replacement. 2nd Issue: Customer Service has steadily declined since I purchased my first unit 5 years ago. When the second unit failed, it took two days to get through to customer service. Then customer service gave me a direct line to order the new element once I removed it from the manifold to confirm it was indeed burned out. It wouldn't come out and I called, leaving a message & sent an email explaining the problem. I replaced the unit while waiting for a response. I never got one. This was the last straw. I'm finished with Eco Smart!

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 From Phoenix, This water heater works excellent, I can run two showers and a sink at the same time with no problems, hot water is fast to get to the back bathroom, most of the installation was very easy, the one thing I could not do was the electrical it required 3 new 40 amp breakers and a fair amount of 8 gauge wire (3 of them) all with a positive, neutral, and a ground wire, which then required all to be placed into a 1" piece of conduit, but all in all it only took 2 hours to do the electrical and 20 mins to mount and connect the plumbing, looks great works perfect and I have had no issues. This replaces a 80 gal old school water heater, frees up a lot of garage space and is saving me $$ on my electric bill. I checked out how easy it would be to change out heating elements and looks like it would be simple, (if necessary) (all parts are guarantied for life) Now I have endless hot water and I would highly recommend it to all. I called in because I wanted my 10% retired military discount, they were great to work with. Ltc. Will C. (USA) Phoenix, AZ

We had to hire an electrician and a plumber both licensed to come out and install this system and the system would not heat the water enough for even one sink faucet. So we call them run some troubleshooting to once again bring the electrician out for a 2nd time. Everything is hooked up fine so they send out a new one and once again brought back the electrician for a 3rd time and plumber for the second time. The same exact thing happened! We had the electrician speak with them on the phone and everything was wired correctly! In the end this system is complete trash and they refuse to admit it. They were rude to me and my wife on the phone after 2 total hours of being on hold. They cursed at me and said we were being rude when we were asking for simply a coverage of the cost of the electrician and the plumber on the 2nd trip. They refused. They don't care about their customers and basically said we were wrong but then I hooked up our old hot water heater and it worked like a charm. This company is terrible stay away!!!

Rated 4 out of 5 by from Efficient Hot Water Today I called the gas company and shut off my service. My old 40 gallon water went out on me 10 days ago. I ordered this 18KW ECO SMART system when it was on sale for 319.00 So far everything works GREAT! The biggest concern you will need to address is you breaker box in your home. If you have a 150- 200 AMP breaker box don't think twice about getting this. I had to have a good bit of ELECTRICAL work done to upgrade for this system. I researched the many options out there. This was what I was looking for. Something that was 100% electrical, On demand use, Self contained, and almost no maintenance for up keep. My brother and I put ball valves in the lines to ease the maintenance and service for the Eco Smart system. It handles with EASE a nice hot water temp in my upstairs master-bedroom shower. This is the farthest point away from the unit. All and all I am very happy so far with this investment for my home.

Rated 5 out of 5 by from ECO-27 I bought the ECO-27 on line. It had a September 19th arrival date, it arrived on the 17th. Since the unit requires special electrical hookup I had an Professional electrician install the wiring and double pole 40 amp breakers. I also had a plumber hookup the Water inlet and outlets. This is required for the warrantee. While we have been using the unit for a week, It has worked as advertised. It is extremely easy to set the hot water temp. you want. I have set our unit for 120 degrees F. So far we have used the unit with 3 hot water sources going at the same time; Dishwasher, washer, and shower with no loss of hot water. One unexpected thing was that in our master bedroom shower, it was taking up to a minute or longer for us to get hot water. Now it only takes about 30 seconds for hot water to get to the shower. If you are planning to buy this unit, be sure to budget for the electrical hookup and pluming also unless your are more of a handyman than I am.

However, the brand I had before was nowhere NEAR as well-made as this. During the 20 years I used that brand, I had to replace it FOUR times due to leaks. And, I had to replace the motherboard twice to to component failure. The Eco27 is simplicity itself. Not convoluted motherboards with a ton of components to burn out. The chambers are COPPER unlike the former brand I had which were plastic or resin. I did a LOT of research before I chose the Eco27. After I installed it (which was a piece of cake following the instructions), I was rather surprised to find how quickly it heated the water. My old unit had four elements and it didn't heat the water as fast as the Eco27 with three. These guys did it RIGHT. Be sure to use their sizing guide to determine which Ecosmart is right for you.

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.
