Worked excellent for my cabins needs.
For 3 people in a house hold it worked as advertised. Here in mid south I started at 115 degrees and it was scalding hot coming out. takes a second but not bad to get hot with about 50 foot of water line to shower from unit.

    The Atmor Electric Tankless Water Heater is efficient and compact! Fits perfectly under a sink, utility room, closet, wherever. Works great for a bathroom that is on the other end of a house or far from the hot water tank. This water heater works inline with your current plumbing and is activate when water flow is detected. This gives you instant hot water until the hot water from your main tank reaches this location. Great size and affordable to run!

    Just recently received this tankless water heater by ATMOR. It is a 13000 Watt and 240 volt heater which includes a pressure relief valve The Continuous Flow of hot water activates with water flow and unlike gas water heaters you can install this just about anywhere as it requires no venting. It does however require a 60 amp double pole dedicated breaker and a 240-volt connection. Also required are standard half inch straight thread water connectors. This water heater can also be installed indoors or out. It has four settings, off, low, medium and high. The hardest part is going to be drilling through your house and adding the number 10 wire from the fuse box to the heater. The great part is going to be not having to waste water while waiting for actual hot water to come out of your faucet! Fortunately my partner is in construction and can do all of the plumbing , drilling and wiring. You may have to hire someone to do all that for you. Overall, it's a yes from me.

    The Atmore under sink hot water heater is a cinch to install under the sink, it gives me hot water as quick as I open the hot water handle. I use to wait a whole minute to get good hot water and now it is as fast as turning the handle. No more wasted water while waiting for it to warm up. The installation is very simple and the instructions are very clear to give you the do's and do not's for connecting it. The hardest part is running the #10 wire from the fuse box through the wall and under the counter.

    This is a very compact little water heater like you would find mounted under a sink. Construction quality is good with almost all plastic components. No assembly required other than attaching the included pressure relief device. Pressure rating is adequate for any normal residential water service. Water flow for rated heating performance is low but is estimated adequate for a low volume shower. This device would be great for a half bath or a utility sink or single shower stall in a remote location like a garage which is where I will use mine. Water side hookup is easy with only two screwed fittings. Electrical requires 240V service.

    This well-designed and compact water heater is 12 inches wide, 7 inches high and 4 inches deep. At the bottom are two 3/4 inch threaded connections - blue one for cold inlet and a red one for the hot outlet. My new sink with dispenser has not yet arrived so the output result cannot be evaluated at this time. The front panel dial gives you four choices - Off, Low, Medium and High.

    The ATMOR 13,000 Watt/240-Volt 2.25 GPM Electric Tankless Water Heater Includes Pressure Relief Device, Ideal for a Full Bathroom appears to be exactly what it is titled it you look at the front side of the box only. Either your bathroom needs to already have multiple specifications before installing this unit, or you'll need an electrician to complete all of the necessary adjustments so that this will work (it needs its own outlet, must be at least 240v, and if that isn't already in your bathroom, you'll also have to make changes to your circuit breaker so that the newly installed outlet can handle it).

    Armor 13,000 Watt 2.26 GPM Electric Tankless Water Heater, that includes a pressure relief device, and is ideal for a full bathroom, was highly recommended to us by a professional, for use in our finished basement. Not installed yet, so I’m relying on expert advice to write this review. The install is quite simple and straightforward, instructions included. The unit carries a 2 year warranty, and 7 year warranty against leaks. No more paying to heat water that you’re not using, as this unit heats water on demand. This will save on utility bills quite nicely! Others, who have this unit, have reported to us no issues and are happy with the tankless heater. So we expect the same results.

    The most important thing is to read the instructions before you purchase. If your hooking up to very cold well water your going to be disappointed! We are in Florida and have well water but our water is not extremely cold like you would find in northern states. I wanted this for my garage sink. I don’t use the hot water long but like to wash my dirty hands in the garage and leave any mess out there. I have ample hot water from this unit. I also clean various parts which require warm to hit water and this unit works great! I also clean and filet fish in the garage so hot water is a must for cleaning up! I needed minimal parts to complete my installation. I already had the wiring and circuit breaker in place when the unit arrived. Plumbing hookup was simple. Has three settings. I have been switching the setting and tried all three. Finally sticking with the middle setting as that seems to fit my needs. Warranty of 2 years on parts and 7 years on leaking is very good. Overall I am extremely happy with the unit!

    Received the Atmor 13,000 watt 240 volt 2.25 gpm electric tankless water heater that includes a pressure relief device, but sad to say cant install as has now to hook up that meets National Electric Code requirements. For on has a metal ko connection plate to mount on a wall then you are to run a conduit to that plate and run bare wires to the electric water heater, but that needs to be in conduit and then it provides to holes in the back of heater to run wire thru, by code you can run wires exposed, so I will not install as only place to drill a KO is on the removable front cover and that will make it so you cant service the unit or reinstall the cover with the conduit installed
