  • Just buy it! It’s plenty for your home.
Pattern Name: Water Heater
Listen I read hundreds of reviews on tons of tankless hot water heaters. This one was the most price friendly but also had the best ratio of good reviews. (We also live in the south so up north I’m not sure if it would be the same due to ground water temps) It was easy to install. Our old hot water heater wires hooked right up to this new one and we used the same breaker, we just needed $10 worth of new fittings to make our old hoses from our old tank hot water heater fit this new tankless one. We ran our sinks and shower full blast and it had no issues heating. Only thing we noticed was obviously a little less water pressure but our house has pretty low pressure in general. It’s old. Also this thing takes up NO space. The only thing I wish is that we could of hooked ours up closer to our bathroom because ours is located in our outside garage on the other side of our house so we still have to let the shower run for 20/30 seconds to let the room temp water get out of the pipes between the water heater and the shower. This is only the first day we’ve used it. But if anything changes I’ll update. Also I read the manual a million times and stressed about it and it honestly took 10 minutes of work. Getting the hoses off the old one took longer than anything. But our wires and breaker were already correct so we didn’t have to change anything out which saves time. One thing I did notice that I didn’t see In any reviews was when we first used the hot water (after purging the lines of course-without it powered on just like the manual said-) it made kind of a loud hum or similar of a dull shop vac sound) only when we had the hot water running in the house. But after a few minuets it stopped and we haven’t heard it since so maybe it was a start up thing. ... show more

  • ECO 11 works great here in South FL
Pattern Name: Water Heater
I installed my EcoSmart ECO 11 on September 12. The basic installation was fairly easy. Running the 6 gauge wire, not so much. I got it done, correctly and up to code, but a major pain. Would hire an electrician if I had to do it again. Many have said they had trouble with leaks when connecting to the unit itself. My guess is that those folks failed to use the included washers. Not surprising since I saw noting in the instructions and only found out about them on the third or fourth YouTube video I watched. The washers are located inside the red and blue protector caps on the input and outputs of the unit. If you didn't check, they probably got tossed out without realizing it. THEY ARE NECESSSARY. DON'T THROW THEM OUT. Since the input and output on ECO11, (and the ECO 8), are 1/2 inch and most water connections are 3/4 in, you will need to add an adapter to both in and out. Don't make my mistake and buy brass. Most brass, while easier to find, is not allowed for 'potable' water connections. I had to return mine and get stainless steel. Minor inconvenience, but avoidable. I found that the easiest connection method for me was to use steel wrapped washing machine hoses. https://smile.amazon.com/gp/product/B0915TVZGY/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Pex pipe would probably have worked, but have never used it before. I did install the 3M Aqua-Pur filter. Easiest for me was at the cold water input just before attaching the washing machine hose. Bought, but did not use, the isolating valves. Tried, but had too many leaks and got frustrated. Since I live alone, I figured I'd only need to flush the tank once a year and will simply disconnect the washer hoses and utilize another set for the flushing procedure. Be a good time to check for any wear on the original hoses. I'm in South Florida, so the incoming water is quite warm. Not like where I grew up in northern New York. The unit works great and will the thermostat goes to 140 degrees, water temp reached 143 degrees when tested at the kitchen faucet. That being said, I keep the thermostat set at 104 degrees. That, for me. is a perfect shower temperature. Just turn the hot water on all the way and once it there, no need to adjust. Why heat water to 120 degrees then add cold water? Not cost effective. My dishwasher has its own built in heater so no worries there. If you do need hotter water for any reason, it's very easy to simply turn up the thermostat and then back down when you're done. ... show more

  • Going strong after almost 10 years!
Pattern Name: Water Heater
I was just washing my hands looked up at my Eco Smart 11,000 W model and thought geez I'll bet you I've had this for nearly 10 years now and the thing works like it did when it was new. So I logged into Amazon to give a review and it says last purchased April of 2016. Incredible it keeps records of all that. But yeah they made a heck of a name for themselves in my opinion. Great product. ... show more
