Product Overview

  • Continuous on demand hot water heater, no hot water tank
  • Electric water heater ideal for whole house hotwater applications
  • Requires 3 x 40A single-phase DP breakers, 3 x 8 AWG wires, 240V
ATMOR ThermoPro Electric Tankless Water Heaters revolutionize hot water heaters with smart flow technology that provides you with unlimited hot water when you need it, without the wait. 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. This eco-friendly unit features the advanced ThermoPro self-modulating system that regulates the amount of energy required to heat water, delivering major savings on your energy bill. The easy-to-use, digital panel gives you full control of the unit for the perfect water temperature every time, while the splash-proof IP54 certifications keep the unit safe and dry. 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. Perfect for moderate to warm climates, the 27kW/240-Volt, 5.1 GPM capacity is ideal for small to medium sized homes running up to four applications at once, such as: two showers (1.5 GPM/shower head), one kitchen sink (1GPM), and two bathroom sinks (0.5 GPM) at inlet temperatures of 73°F. Remember inlet temps vary by location and seasonality. Colder climates limit the number of applications that can run simultaneously. Selecting the right water heater depends on your incoming water temperature, flow rate, and desired output temperature.
  • Electric water heater is energy efficient and easy to maintain
  • Requires 3 x 40A single-phase double-pole breakers, 3 x 8 AWG wires, 240V
  • Endless hot water with no wasted water or energy
  • Digital temperature control allows you to set your temperature in increments of 1F
  • Industries only unit to receive splash-proof IP54 certification, allowing point of use installation in near showers and sinks
  • Save up to 50% on electric bills compared to a traditional tank water heater
  • Utilizes three 8-Gauge wires connected to three 40 Amp double pole dedicated breakers
  • Thermostatic control range from 90-122F
  • Easy to use, set-it and forget-it digital temperature control
  • Durable and corrosion resistant stainless steel interior assembly allows for heating efficiency and longer life expectancy
  • LEAD free
  • Easy to maintenance
  • No venting required

why Do l lights dim when heater in use & how to fix it.

why Do l lights dim when heater in use
Asked by: Goin4wrd
Dimming lights? First, I am NOT a licensed electrician, but there are some straight forward questions that must be answered correctly. What amperage is your main Breaker Box? It must be 200 amps MINIMUM. What gauge is the wire run from breaker box to water heater? It must be #8 copper or larger. If the feed wires to the hot water unit is too great of distance (I do not know the exact distance), there is 'loss/resistance' in the wires, so possibly need to upsize to #6. Are the new 40amp breakers used the same brand as the panel-- this is a long shot as a possible problem. Are the new breakers 'thin' 2 pole or normal thick 2 pole? If they are thin, you might be drawing an excessive amount of power from one of the legs in the panel, dimming lights on only that leg. Normal thick breakers 2 pole breakers are designed to balance the load evenly across both 120vac legs. Lastly, if you have an all electric home (no gas appliances), even if you have 200 amp service, it may not be adequate depending on the other loads in the house. I have installed 3 of these in my own homes with no problems electrically. I highly recommend an electrician verify your unit is installed properly and that the electric load in your home does not exceed the incoming service, sooner than later.

how many units do i need to get hot water TO bathroom laundry ect? are they all over the house?
Asked by: gman
This is not an undercounter unit that supplies task related hot water. This supplies the whole home. If you are looking to do task specific hot water, you should consider something smaller that runs on 110v (standard plug)

ThermoPro 27 kW / 240-Volt 5.1 GPM Stainless Steel Electric Tankless Water Heater with Self-Modulating Technology is rated 4.0 out of 5 by 80.
Rated 5 out of 5 by from My wife and I have very hard well water on our farm and go through 80 gallon water heaters every ... My wife and I have very hard well water on our farm and go through 80 gallon water heaters every few years. This time I decided to go tankless and after many months of research we decided on this one. I had my reservations thinking that I would lose water pressure, have run only hot water to get the temperature where we were used to having it, etc. My concerns were misplaced and the installation was fairly easy even with having to run wire through the attic. At this point we are both very happy with the tankless heater and have no regrets. Bear in mind that you will have an additional one hundred fifty dollars or so in materials necessary to install this heater. even at that I still came out cheaper than buying a tanked heater and i'm looking forward to seeing if I saved anything on the utilities. Yes I would recommend this product and it will provide enough hot water to fill a large Jacuzzi and very long showers.

Rated 3 out of 5 by from Good product but few issues We've been using this unit for about 3 months and overall we like it but there are a few issues. First thing we noticed is that the temperature at the source fluctuates when another source is turned on (i.e. Shower temperate changes is someone turns on a sink). Second, the unit just stopped working the other day. Water was flowing fine but no power to the unit. Checked the breakers, they were fine. All wiring was fine. Checked the manual for trouble shooting and it was pretty much useless. Turns out there are 3 reset buttons inside that aren't even mentioned in the trouble shooting. 1 is easy to see but the other 2 are hidden near the top and are a little difficult to get to. Reset all 3 and it works again.

Im waiting for my replacement unit and when I get it I am retuning to Home Depot for refund and am going to go with a Rheem.Super ticked I have had to go through this 2 times in 3 months.

Rated 3 out of 5 by from This unit heats the water okay but lacks consistency. ... This unit heats the water okay but lacks consistency. The temperature fluctuates somewhat while taking showers even when no other water is running. This may be attributed to the operation of our well pump / system but should be taken into consideration when purchasing this type of system. Some of the pricier units claim to better regulate flow which may keep the temperature more consistent.
