Product Overview

The EcoSmart ECO 36 Electric Tankless Water Heater is assembled with patented self-modulating technology to regulate exactly how much energy is needed to heat the amount of hot water needed. Not only does this tankless water heater save you money, it is also compact and wall mounted to save valuable storage space. If you have a need for a high amount of hot water, this is the right choice. Ideal for the northern United States, where incoming water temperatures can reach as low as 37°F, the ECO 36 is capable of heating nearly 3.5 GPM at this low temperature and can handle up to two showers running at the same time without running out of hot water. For homes in the southern United States, the ECO 36 is perfect for large tubs or high demands of hot water between multiple applications, handling up to 6 GPM that can run four showers and a sink simultaneously and never run out of hot water.

Customer Questions & Answers

Will this work for a mobile home?

Asked by: Susie
The most important thing to consider when doing any kind of work on a mobile/manufactured home. If you ever plan to refinance or sell the home you should start with the state office who inspects mobiles. In the state of Washington, for instance, it is the Labor and Industries (L&I) who does the inspections. They will tell you whether something is allowed or not and what to do to make it allowable. They place a sticker on the end of the home that every appraiser will look for if you have changed anything like: from an electric furnace to a heat pump, or changed the water heater to a tankless or even penetrated the envelope of the house to put in a door. This is not an expensive permit or procedure, but very important. Contractors or craftsmen don't always know what is allowed on a mobile.

Total installation cost

How much would be the total cost to replace traditional water heater tank with this one? Cost should include all needed electrical/plumbing jobs.
Asked by: tankless
The cost will depend on your contractor(s). The required four 40 amp 240 V breakers (I put in 50 amp breakers) and wiring was easily done in an hour, but the unit was installed only 3 feet away from the breaker box. The plumbing time was also under an hour. The cost of the materials needed—breakers, 8-gauge wire, relief valve, quick-connect/flush connections and plumbing connections—was almost $200. Note: I ordered the "Watts LFTWH-FT-HCN Service Valve Kit for Tankless Water Heater" from Amazon, on sale for under $100. If you have to run wiring for any distance, it will be very costly. 8-gauge wire is very expensive/foot. I think it was over $2/ft, and you need to run four sets of wiring from the unit to the panel, so that's over $8/ft. If your contractor is unfamiliar with tankless technology, the instructions are clear and easy.

how does it work with a Samsung h/e front load washer?

We are in the medical field and use very hot water to wash scrubs. With a minimum 0.25 gpm activation I am concerned our washer will not get the hot water we need. How will it do with the eco 36?
Asked by: DLwalker
I am a DIY'er so these are opinions and thoughts rather than concrete answers. Hopefully there is something here you can use. You can set the temp very high on the unit. Since the hot water requirements are intermittent during a particular cycle, and either "on" or "off", I assume you'd be fine. I experimented in a utility sink near the unit to see how slow the flow rate could be to keep the unit supplying hot water, and I would assume that when the washer adds hot water during a cycle, it would be in "bursts" and not an ongoing "trickle.". You might want to check to see if the washer supplies any added heat to the incoming water with particular cycles.

Rated 5 out of 5 by from Great Easy installation and the space it saves is amazing. We especially enjoy watching it shut off immediately after hot water stops flowing....it feels like saving money!

Rated 3 out of 5 by from Please read before buying Please make sure that even tho the paper work and this web site.Says that you only need 200amp service. The eco-smart web site says both. I contacted eco-smart and they told me you actually need a 300amp house hold service to run this.So if you don't have a 300amp service I would advise you not to get this model because of the cost of changing out you service. I have pointed this info to both companies. So they are aware of this info. Now as for the unit it self it is a nice unit even tho mine got damaged in shipping. In which I only found out after hooking up the fuse was busted . so I replaced it and come to find out the circuit board had a short in it. So I took it back and ordered a 27.

Rated 4 out of 5 by from Not bad at all! Installed giant jetted tub that the water heater couldn't handle. Bought this and installed it exclusively for the tub. Works great! Only issue I had is tripping the breaker while running the water and the jets simultaneously. This speaks more to my limited electrical service though.

Rated 5 out of 5 by from Tested perfectly in a Montana winter. I bought this unit on sale and installed it last July. It probably took 90 minutes, and the materials were around $180. I'm a DIYer and it was no problem at all to hook up. Very simple (except the warranty requires license numbers from electrical and plumbing contractors, but I probably saved enough to buy a new one if something goes bad). The temperature in the crawl space under my cabin is 35° (which is where the pressure tank is and where the water is temporarily stored). It's still cool in summer, maybe 58°. To compensate for the low starting temperature, I need to set the temp at 125° at the unit to get it 80+ feet to get all the way to the shower at 112°. The temperature is rock steady (once the pipes warm up) and instantly hot no matter how many dishes, sinks, washers and showers are going on at once.

Rated 5 out of 5 by from Excellent alternative to tank-style. This unit makes perfect sense for many reasons. I only use a few gallons a day most of the time. But several weeks a year I might have 4-8 people needing showers, laundry, dishes, cleaning... The temp is incredibly steady and perfectly predictable, adjustible and economically smart. Installation was simple and quick. The 36 kilowatt model is overkill, but my well is 400 feet down and my crawlspace is 62° even in summer, so I wanted to be sure the water could always be hot and ready, even in Montana winters. No regrets.
