    Very easy to install. I'm in Florida and using this for my whole house. The only issue is when both showers are running the water pressure drops quite a bit. However it's still ok to use both showers at once. It's perfect if your power supply is limited. I would have had to upgrade my service to use a bigger unit. I am very happy with it. I do recommend installing a sediment filter on cold water supply. If anything gets in the unit it will stop working but it's easy to rectify the problem by ... read more just disconnecting the supply at the unit and removing debris from the screen. Had to contact customer service to figure that out and they were extremely helpful.

    Fantastic machine!
    Its hard to believe this little unit will replace a 40 Gallon water heater! But I must say I was happy to say good " buy" to the large antiquated tank! I have a 2300sq foot home in the mountains of southern California we are at about 4800 elevation. So we get a little snow and cooler temps. I had to wait 2 mins for the old water heater to reach the bedroom shower, now I only have to wait about a min and a half . but once it comes hot, it does not stop! Family over for the holidays 3 showers in a ... read more row it produces endless hot water and 2 showers at a time are good as well. 6 months of use should have done this years ago. I spent a little time to install the heavy gage wire to the main panel but installation was a snap. Ps if you have a bath tub that runs at 5-7 gallons a min .... use a 2.5 gallon per min water saver end.

    Good product so far
    The 3.0 GPM Electric Tankless Water Heater is smaller then the one I was replacing and easier to install. It is working great so far, I will see how long this one will last. The one I had only lasted 3 years. and the part that went out was circuit broad that was not under the warranty.

    Great for a small house.
    Took out my 30 gallon tank and put this in our small house. 1 bath 2 bedrooms . Had to run new wiring. 6 gauge wire with a 50 amp breaker. Works great! We never run out of hot water .

    Amazing Product
    This water heater is quite the space saver and installation isn't difficult. I'm having happy with this purchase and I'd recommend anyone to give this tankless water heater a try.

    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 ... read more Montana winters. No regrets.

    Best of tankless water heaters
    Very easy to operate. Had to add another electric panel to accommodate the three 40-watt load from the heater.

    worth the buy
    Need to have an electrician do the install, hard to find the proper breakers for this. Water takes a minute or so to make it to the variuos facets in the house, but once the hot water comes it's endless. Can even have 2 to 3 areas using hot water and still have suffiecient hot water for a shower.

    Simple install, works great, compact
    There are differences with tank heaters, some of which I did not expect, such as the hot water seems to actually take longer to reach you. This is probably good for my electric bill since I am not paying to keep my un-insulated copper pipes warm 24/7. It appears to reduce flow rate to maintain output temp. My instinct was to just max the temp and mix with faucet, but I achieved improved performance by lowering it to 120 (max is 140), which allowed more flow on straight hot selection at faucet. ... read more In the shower, it seems there may be a feedback loop of some kind as my well pressure tank vs. cold/hot mix vs. stages in the heater vary. Sometimes it takes a while to dial in the temp in the shower... and then it drifts a bit. In my application, I needed to free up some space, was able to install the unit 4 feet from my breaker panel, had the experience/skill to do it all myself, and had an ancient tank heater, so it was perfect. I am totally happy with the choice.

    Nice and easy
    This tankless water heater was so easy to install, even the plumbing went off without a hiccup. Now our electric bill is lower by about 30% and we are just getting use to how to set the temperature for best savings.

    I have looked for these at an affordable price for 0ver three years.
    I was unable to find anyone that knew anything about this type of water heater until I went to the Home Depot store in Lee's Summit MO. The staff there are knowledgeable, and took the time to help me find the size that would best suit my needs. I had been using Lowes for all my building needs, but now use Home Depot. The product itself is of excellent quality, and I expect many years of hot water for much less that any conventional water heater could give.

    Heating elements fail
    Worked great for 6 months then came the cold water, lukewarm, cold etc.. Tech support sent both heating elements, hot water again. The original elements were corroded beyond belief and the cold water element was nearly burned in half, I have a whole house water filter that traps 99% of sand, silt what ever. We like the unit, it's an energy saver however, if you purchase one call tech support right away when the water temperature starts to fluctuate, it's not the control board or the sensors, ... read more it's the heating elements

    Love, love, love it!
    We have hot water within a few seconds, and the water stays hot no matter how many showers are in use. We had an electrician and plumber install it. We had to contact the tech support of Siebert-Elton because the water was taking a long time to get hot and would not stay hot. Tech support had us flush the water lines to remove any gunk/blockage which solved the problem. We have had hot water ever since. Great product!

    I have three bathroom and the system is working great. I would recommend. The electric installation is the only issue that I had, you have to hire a electrician to get the new breakers installed.

    Easy to use and install!
    The hardest thing about installing this product was figuring where I wanted to mount it. It was easy to install and even easier to set up. I ran 4 sinks, 2 tub/showers and a washing machine simultaneously and it kept up.

    Great purchase; best price
    We ordered 2 units which arrived quickly and properly packaged. Nothing broken. The units went up quickly due to their compact size. Our code officials require overflow drains and disconnects on both circuits which can add to cost, but we were already prepared for this. Just keep in mind. Building inspectors commented at how cool these units are. With the LED displays and stainless steel enclosures, they add a serious "bling" factor to the mechanical room of the home we custom built. Owner really likes them!

    Very small and it's hard to believe that it could deliver hot water for showers, but it does. Nice and sleek looking with a Nicole digital read out I had it installed for my summer home and the real test will come when there is a house full of people in just a few short weeks. I will give a further update at the end of the summer. So far so good

    Best heating!
    This is a great heater: I can set up the output temperature and no matter the water flow it keeps heating the water at the same temperature! We could run 3 showers at the same time, which is a rare occasion but we needed one as the whole family had to go out and the water heater kept the heating capacity just fine! It was easy to install as its size fitted so well that we saved space for other stuff we wanted to keep in the closet. Definitely recommend it.

    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 ... read more life. I would recommend this product to anyone thinking about going tankless. Extremely happy customer here.

    Fairly easy install
    Was a decent install for a semi experienced person in electrical. I like the digital temp display and easy temp adjustment. So far only used for a month time will tell how well it works. Could use a list of size wire needed for the hook up I had to go online to see what size wire was needed. It does say size and how many breakers for the model.

    Excellent value
    The water heater was easy to install. Having the necessary power available is important. The ability to heat the water sufficiently is predicated on the incoming water temperature. Be sure to check the heating chart prior to purchasing the unit. The unit has been in about a month and is installed in our Church. It is particularly beneficial because the water is only used a couple of days a week. In this case we look forward to even more energy savings than with a tank heater. The other ... read more beneficial part is that it only turns on the number of heaters necessary to actually heat the water. In the bathrooms the lavatories only need one of the three heaters to sufficiently heat the water. As expected the kitchen faucets require more. This ability also enhances energy savings.
