  • Works okay to wash hands and small stuff
We wanted to use this in our shed for hot water without needing to use a hot water tank for occasional use. It uses a 40A circuit which is hardwired in and the plumbing was easy. The 3kw model works okay for the one sink and the water doesn't get real hot. Works okay to wash hands and small stuff. The construction did not feel cheap and we expect it should hold up well. ... show more

  • Great Value
This was my first experience with the tankless water system. I had been looking into them for about two years and loved the idea of using them but couldn't figure out what application would work best for my house. I finally decided that this unit would work best installed in the guest bathroom because it is not used very often and my guests aren't using or needing tons of hot water all at once. Although the installation of this seemed straight forward, I opted to have professionals (some professional friends) do the work. I must admit that the job was rather simple and the whole process was done in under 2 hours. It is installed in the cabinet under the sink and the hot water is set at a comfortable hot temperature and sure enough I was able to turn the hot water and get it flowing very quickly (seconds). The unit is rather quiet and doesn't have that "whooshing" sound I get when the gas water heater starts up for the rest of my house. So far, the unit works and functions exactly as described and I haven't noticed any leaks or problems (knock on wood). ... show more

  • Quick heating, steady flow, compact size, good investment
This electric tankless water heater works as expected. • First, I was unable to install it myself because of all the specifications for this product, so I was afraid to do it by myself, so I had to get someone to do it for me. It took slightly more than an hour to do so. • After being installed, it heats water quick and it provides a steady flow of hot water with good water pressure. • The size is compact, which is really convenient because I have a small apartment and it doesn’t take much space. I have no complains about it, it feels of good quality overall, and it works as expected. I believe it is a good investment. ... show more

  • Hardwired not plug in
I was hoping to replace my current gas tankless hot water heater with this electric one. I have a 220 outlet nearby from an old hot water tank, and my intention was to plug it in and reroute the plumbing. Unforunately this is hardwired only, and will require an electrician to install. I will also need to get a plumber, so the installation is more challenging than expected, but not impossible. The water heater is of good size, and seems to be made well. I will update if I have any issues after installation. ... show more

  • Works as Intended!
we have this installed in our pool shed so we could add an outdoor shower -- it does a great job since it's far away from the house - we only have to heat the water as it's being used. It is hard wired - and you need to understand that it will heat the water according to the water INPUT temperature, as well - so if the water is colder coming in (ie: winter) it will take longer to heat the water to the desired temp or you will get a slower flow of water at the temperature you want. For our summertime use, and only one shower/sink - this is perfect. ... show more

  • Very high quality
This is a heavy-duty water heater that heats up fast. I have this connected to my kitchen water faucet and love it. My kitchen is a ways away from my whole house water heater so it's very convenient and saves electricity and water, so it's a win-win for me!

  • Have a good plan for this including power lines
This water heater is quite compact. Comes with 1/2 pipe fittings for connecting to your house and a couple direction sheets (with the wall mount pattern for screws). When installing, they warn to be sure to fill the water passages BEFORE power is turned on (as the biggest problems with all water heaters is what they call "dry firing" from power put to it without water). Many may look at tankless water heaters like this and quickly say "why not?" It doesn't take up the space of a huge tank, it costs less than tanks, and you never "run out" of hot water as major advantages. However, you need a much bigger power circuit for this (like 60 amp circuit for the 14K unit) rather than 30 amp for tank units, so you can't just put this in place of a tank unit you may have. Also this can only heat about 2 GPM water from ~50 to 100 degrees from the 14K power (so if running a bath needing 40 gallons, it'll take 20 minutes to fill versus 8 minutes with a tanks preheated water). Some may say "it heats the water, but not enough" where if the winter water is 40 coming in, this may only heat it to 90 from the same power. So beware that it can seem to "change" depending on seasons like that as it gives you the same set rise in temp regardless of 60-110 or 40-90. You can slow the flow down a bit to let it heat more, but not sure if that is what you want. If you would want something you can run off a backup generator or inverter, a 7000 watt can do the 30A, but you'd need 15,000 watt for this. That power demand also shows what the power companies are needing to supply for you when it goes (which many give no thought to, but if everyone turned on the same things all at once in a city of 50,000 homes, that can be enough to need another Hoover dams full power). Some may also assume they always have plenty of power available from the grid, yet a 100 amp box can end up with 60 going to this, ~30 for a house heat-pump and leave near nothing for the rest of the house items without overloading the 100A main, so check on that as well. If you have a 200A main, you're much less likely to have an issue. So as the old saying goes "fail to plan and you plan to fail" which I hope you don't have happen. ... show more
