Review: The best value in the 11KW size. Works better than expected - We purchased this water heater based on comments here and like others, we agree that it is a great water heater. We are using it as a whole-house water heater replacing a sixty gallon tank that started leaking. We expected that there would be some adjustment in going tank-less and using an 11KW as a whole-house water heater, for example like not using other faucets while showering, etc., but we were willing to make that sacrifice because we were going to be saving money on the heater, and on electricity with the bonus of doing the right thing for the environment. Well, this heater exceeded expectations by a LOT. We keep it set at 110 degrees which makes for very hot shower but not scalding and no problems using other sinks at the same time. My wife told me she took a shower while the dishwasher was running and expected it to be "cool" but to her surprise there was no problem handling the dishwasher and shower at the same time. It has been about a month since we installed the water heater in our 4 bedroom, 3.5 bath house and we have forgotten that we are heating water on demand because there is no noticeable difference compared to when we had a sixty gallon tank. One of our showers is a double shower and I tried that out, no problem the heater handled both fine with no reduction in temperature. You should be aware our house is a Florida house so our city water comes in at around 68 degrees. If you had well water you will have different results as you will be heating much colder water. One other thing to note, if you take a bath you will want to crank the heater to higher temp, it is so easy with the knob and digital readout I taught my daughter to crank it before her bath so she can add extra hot water to "freshen" up her long and hot bath otherwise 110 degrees isn't hot enough to heat up a cooled bath do to rapid heat loss. You can buy the remote control for about forty bucks and adjust the heater setting from anywhere, or just keep your heater set to a higher temp. We like running it at 110 so that we have maximum energy savings and eliminate scalding risks. I highly recommend this heater, keep in mind that you need upgraded wiring, you will probably have 220 volt electric for your existing water heater but ours was only 30 amp and this one calls for 60 amp so that means getting MUCH thicker wire that is expensive and hard to pull. If your heater can be located close to the breaker box you will save money in wire and the hassle of pulling super thick wire. I bought wiring and breaker for 50amp by mistake and didn't notice until after the installation was finished. We must have never drawn more than 50 amps because the breaker has NEVER kicked even running two showers so I plan on keeping the 50 amp breaker as the wire we used is safe for only up to 50 amps and I'd need to replace the wire to even thicker.
Review: Easy Installation and Great Performance from a Tiny Water Heater - It's surprisingly easy to install and works great. I'd anticipated a significant performance loss when switching from a traditional water heater to a tankless model, but this thing is awesome. Instead of using a low flow shower head I went with a pressure enhancing head, the thought being that why should I limit the flow of water before I had the chance to find out exactly what the capability of the heater is. If the heater wasn't capable of keeping up with the flow I could simply turn down the volume of water, and the pressure enhancing shower head would make it tolerable. As it turned out water pressure wasn't a problem. One neat thing about a tankless heater is that you no longer have to use cold water to bring down your hot water temperature to a tolerable level. If I want hot, but not scalp scalding hot, I simply turn the hot tap to full and I'm set. If I want crazy hot I turn the hot water volume down about 20 percent and I'm lobster red in no time. I'm saving money on the electric bill by not preheating water 24 hours a day, and I have unlimited hot water for when I wanna zombie out in the shower. If that's not a win - win I don't know what is. The only real downside to a 220 volt tankless heater is that because it pulls much more current than a standard water heater you will most likely need to upgrade your existing electrical wiring. The paperwork says that it needs 6 gauge wiring, the largest I had on-hand was 8 gauge. For my short wire run it turned out to be plenty. Even after a long shower the wire temp remains perfectly cool to the touch. I also had to upgrade the existing breaker to a 60 amp model. Changing a 220 breaker sounds intimidating, but it's extremely simple. There are only three wires from the water heater to deal with. The red and black wire go to the new breakers wire terminals (doesn't matter which goes to which terminal) and the ground wire goes to a ground lug inside the electrical panel. Study up on the components of your electrical panel and follow basic safety procedures and you'll be fine. The water connections are super simple. The heater comes with a choice of a compression fitting for copper pipe, or a threaded fitting for use with whatever type of plumbing pipe you're using. I used the threaded connector to connect pex piping. If you've never used pex, think plastic bendable water pipe that can be snapped together to whatever configuration you need using press fit connectors. Press fit connectors are also used to connect your new pex to existing copper pipes. Snip snip, click click, and you're good to go. Gone are the days of soldering copper pipes till you're mad at the world. Having installed this unit in just a couple of hours as a newbie, when and if this unit dies I feel confident that I can easily install its replacement in less than thirty minutes. A water heater that will pay for itself in less than a year, AND reduce future headaches? Why the heck not?

## Questions & Answers

**Q: what amp breaker is required?**
A: Well I hate to be the one that burst all you hot bubbles, BUT #6 gauge wire is TOO SMALL. I don't want to start citing NEC Codes , but ya'll forgot to factor in "continuous duty." 
The the unit is 13kw at 240 volts , Basic Math 13,000 / 240 = 54.167 x 1.25 = 67.7 amps .
 Artical 310.16 table for wire amp and sizing, ROMEX House Wire is rated at 60c which according to the table #6  is only good for 55 amps, number #4 is good for 70 amps . This is due to the heating effect of the wire while in continuous use (water heaters are listed continuous duty). The Breaker can be any size up to 70 amps unless specified by manufacturer.
 Always go by manufacturers specification or better. 
This is why warranty is voided if not connected by a licensed electrician and your house burns down!

**Q: My house is wired 110V. What additional items do I need to purchase for the conversion?**
A: Most homes in the USA are wired with both 110 and 220 volts available in the breaker box. If you have an electric stove with an oven it no doubt runs on 220 volts. If you have central airconditioning it will most likely run on 220 volts. Just look in your breaker box and count all the circuits. read the numbers on them... This water heater will need another double 60 amp breaker. Check to see if you have space in the box, look for blank plates in the column of breakers. If this is too much information for you then you'd be better off getting an electrician to at least help you with the job.

**Q: The warrenty says that this unit must be installed by a licensed electrician and plumber, for them to honor the "life time warrenty." why?????????**
A: Hello Bob, The reason is the same as why an innumerable number of gadgets around the world have that little "warranty void if removed" label. Because getting inside of one requires a certain level of training and expertise. Same with this unit. GadgetsGo is an authorized Ecosmart dealer. Kind regards,HenryGadgetsGo

**Q: Ours has only been in service for less than a year - will not adjust temperature to anything above 85 Deg. F. What do you think is the problem ? kds**
A: My only guess is that the rheostat (variable resistor) that the temperature adjustment knob is attached to may be faulty. If that isn't it then I don't know. Sorry.

### ⭐⭐⭐⭐⭐ Better Than The Rest
*by W***R on December 1, 2025*

This was purchased in Nov. 2018 to replace a propane tank water heater with an efficient electric tankless water heater, and it performed flawlessly until last night when it died in the middle of my shower. A replacement propane tank water heater costs between $750 - $800 and has a usable life here because of the hard water of 8 years, and the pilot light uses about 6 gallons a month. At the local price of propane, that's about $22 a month, around $265 a year, PLUS the much greater cost of keeping that tank of water constantly hot. This electric heater costs about $200 with the tax and unlike the propane one, there's no further costs if you don't use it. The monthly average use probably costs about the same as just the pilot light does, with propane. This heater has a lot of bad reviews but still less than all the others. A lot of people complain about customer service but it's bad everywhere anymore, which is what you have to expect for stuff NOT made in the USA. If it doesn't work, ship it back and try again. If you paid a plumber, then you're out the money no matter what brand you buy. Just saying, after reading many of those reviews, that we have to take our chances anymore. Start making everything here in the USA again if you want products that last.
