ATMOR 900 series Electric Tankless Water Heaters revolutionize hot water heaters with technology that provides you with unlimited hot water when you need it, without the wait or worry of ever running out. By automatically activating once water flow is sensed and shuts off when it stops, you'll lower your water consumption and eliminating costly water waste.  The ATMOR Electric Tankless Instant Water Heater is the eco-friendly, efficient and convenient solution you have been looking for, delivering an endless supply of hot water instantly at the point of use only when you need it. It is suitable for both residential and commercial applications, even in your RV, so you can enjoy a continuous flow of hot water whenever you want. Best of all, unlike a gas water heater, the compact design requires no venting, giving you the flexibility to install anywhere inside your home or garage.  The compact footprint of this device can be installed against the wall either under the sink out of sight or near the point of use, where its elegant design blends into your home environment among other appliances.  Remember inlet temps vary by location and seasonality. Selecting the right water heater depends on your incoming water temperature, flow rate, and desired output temperature.

Questions & Answers

Will this unit be ample for a kitchen sink, dishwasher in additionion to a commode and bathroom single sink

Asked by: hank
no i unit per fixture

So does this unit replace the traditional water heater or do you need to buy something to go with it?

Asked by: Dulces
It is a small unit designed for a single bath or under the kitchen sink. I think you will need a larger unit to heat the water for a whole house. If you get the right sized unit it will take the place of the traditional water heater and save the space.

Can this unit be put in line after 12 gal. electric water heater just to feed a single shower only? In cool area at 1100ft. above sea level.
Asked by: KW
I live in central PA and this handles my shower, kitchen and bathroom sinks without any help. Water is as hot as you set it. This unit replaced my 40 gallon hot water heater and has saved me a bundle of money in the year that I have been using it.

8.5kW/240-Volt 1.23 GPM Electric Tankless Water Heater with Pressure Relief Device, On Demand Water Heater is rated 3.7 out of 5 by 22.

Wiring the electric into the electric panel, which was done by my neighbor ( an electrician ), was the only thing I was not comfortable with. Other than that fairly easy. Works good, its not spit second hot, but doesn't take long for hot water to come out. The water gets very hot, so I you like very hot water its for you. I would recommend to friends and would buy again if needed.

It doesn't have enough room to wire it with the size wires it says are required and the wire sizes it says are needed are wrong. No relief valve. Don't waste your money.

Rated 5 out of 5 by from Compact heater I wanted to add hot water to my 3,000 sq ft workshop. As the workshop is not used everyday, I didn’t want to add a wasteful tank water heater, so this instant hot water heater seemed ideal. Installation is very simple, requiring you run 220v power and a 1/2 inch water pipe to it. I used Romex SIMpull 6-2 Type NM-B , and PEX piping, both from Home Depot. Like most instant water heater, this unit suggests you add a flow restrictor aerator. I tested with the flow restrictor attached and was able to get as high as 130 degrees, even with the restrictor removed I got a very comfortable 105 degrees at full flow. The heater has a very small footprint and can be installed under the sink if desired. The heater has 3 heat settings, controlled by two switches. Clean up in my workshop just got a whole lot quicker and a whole lot more comfortable.

Rated 5 out of 5 by from Hot, Hot, Hot Water! We have this installed in an outbuilding on the other side of the pipe that runs to the house. because of this, we couldn't connect to the house hot water heater. This is perfect for hand washing, dish washing and other small things. We use it in an area where we are taking care of puppies and need to make sure there is no cross contamination. The water gets hot enough that we don't have to worry about that. I would not consider using this as a full time shower or for filling a bath tub. The amount of power it uses would be cost prohibitive. Installation of the piping was easy. Pretty much, connect it to the water source, (we used red and blue flexible plumbing pipe) and then connect to the sink. Plug it in and you almost have instant hot water!

Rated 4 out of 5 by from Works well but limited applications product installs fairly easily if you are familiar with basic plumbing/soldering or using shark-bite type connectors. this cannot be used for more than 1 fixture either sink or tub/shower NOT BOTH. relatively easy and small to install under inside or behind the vanity or tub/shower. Provides virtually instant hot water to the spigot. Saves energy especially if you are used to using electricity via a standard hot water tank. this unit only fires up upon demand! Down side is you will need 1 unit per fixture so that means 1 for laundry 1 for each bathroom fixture and 1 for the kitchen. I expect if statistics are true to form they will more than pay for themselves in less than a year!

Rated 5 out of 5 by from Great compact appliance, simple to install........... This product is simple to install, assuming you have 240v power readily available. It is well built and attractive enough that in many settings you would not feel the need to conceal it. The compact design makes it easy to place almost any where. Customer service is very helpful if you should have any questions.
