Product Overview

  • Most versatile tankless water heater with the most vent options
  • Eco-friendly, Ultra Low Nox burner
  • Highest-grade dual stainless steel heat exchanger for longer life
Engineered expressly for the North American residential market, the EZ Series of high-efficiency, condensing tankless water heaters from Noritz America are designed to cut installation time and cost when replacing larger, storage tank-type units. The Energy Star-rated EZ98-DV and EZ111-DV (Energy Factor: 0.97) join the previously released EZTR40 to provide professional installers and their homeowner-customers with a wider range of tankless options, covering the majority of residential, tank-replacement opportunities. The Noritz EZ Series heaters are the best solution for an easy tankless installation.
  • Both new EZ models have their hot- and cold- water connections located on top of the unit not the bottom, like most tank less heaters, this positioning allows the flexible water lines used by the previous tank heater to be quickly and easily reconnected to the new unit
  • Optimizes the perfect air/fuel ratio based on demand for better efficiency with less moving parts
  • Inside each EZ model are 2-stainless steel heat exchangers that have a greater resistance to corrosion and scale buildup than other materials, thereby boosting system life
  • Noritz connect app is compatible with both of the new units, allowing for wireless remote control of -heater functions, as well as diagnostic and maintenance reminders
  • Endless hot water
  • Energy savings
  • Space savings
  • High efficiency
  • Durable

Does this have a recirculating feature?

Does this have a recirculating feature?
Asked by: JJ
NOPE, and you will be waiting endlessly for your hot water to arrive. It's in my home now for less than a day and already am regretting this decision.

Asked by: Dave
Thank you for your interest in the Wi-Fi adapter! The Wi-Fi adapter is used for remote operation, setup and monitoring the tankless water heater. There is an app for iphone, etc and Android. Unfortunately it cannot connect to motion sensors.

Does this particular model include the "Bundle Kit" that comes with other EZ Series Tankless Hot Water Heaters? If not, is there some way or a place to find out exactly what other items would need to be purchased for the install? Is this model a "special" Home Depot only model?
Asked by: CaliforniaGirl
No. Comes with NOTHING. Cost me hundreds of additional for everything my plumber needed.

To Noritz: This is in response to your reply to my previous review which was posted here. I am writing this add'l review because there is no 'reply' function on here and so it's the only way to tell you that what you say is worthless because there is nothing wrong with my unit. This was your previous response to me: Response from Noritz September 7, 2018 My sincerest apologies that you are having difficulties with your recent install of the 9.8 EZ Series. I would recommend calling into our technical support team who is extremely knowledgeable and would be able to monitor the unit to ensure that it is functioning properly. This unit comes with an external keypad/thermostat display which allows us to monitor flow rate, the exact temperature of the water leaving the unit, and a multitude of other features to ensure the unit is functioning properly. Please call 866-766-7489 and speak with one of our technical service agents who are located in Fountain Valley, CA and are more than happy to walk you through these procedures. Our team is here Monday-Friday 5:00 am PST to 6:00 pm PST and Saturdays 7:00 am PST to 3:00 pm PST. I would be more than happy to answer any further questions you may have. Sincerely, Noritz America. Well... I called the number just as you recommended and spent two hours on the phone with your reps, and sure enough, as I suspected, there is nothing wrong with the unit itself. Don't pat yourself on the back just yet because that only bolsters my previous point, which is that even with the unit working as it should, it still takes more than triple the amount of time for hot water to reach the faucets! And what's even more frustrating is your tech rep's "solution" to the problem involved ripping up drywall on all levels of my townhouse and installing a recirculation pump. That is not feasible for me economically. So now I am stuck with wasting gallons of water daily while waiting for hot water. Very frustrating. Regret this purchase.

I was extremely leery going into this as I am one who researches and 2nd guesses everything, have been considering this tankless upgrade for over 2 years now. SOOOO glad I waited for this model to become available!! Even my installer did his research on it and said this brand is as solid as they come and the dual stainless steel heat exchangers is where its at!! I have been around other tankless units and you can hear them rev up/hum when they start producing the hot water, not annoying, but you can hear the hum of their fan none the less...but NOT this quite guy, wow!! SUPER quiet, I was standing next to it with 2 showers running and had to put my ear on the unit to even hear the slightest whisper of a hum!! My installer was super impressed with every aspect to this thing and converting from a regular tank with the lines coming in from the top is a cinch as the inlet/outlet is on the top, just like a regular tank. Oh yah, after install, he turned the hot water on all 3 showers, 1 tub and a few sinks in my house and he said out of every one the water was still plenty warm to do the trick. So I know for certain this 9.8 GPM unit will give us plenty of hot water for 2 or 3 showers running at a time!! You will NOT be disappointed with this thing, I know we sure won't be for years to come!

However i find the water not as hot and its the middle of august just wondering how it will be in December . The highest settings is120 degree. while taking a shower the water gets cold . if i didn't spend the extra $$$ with venting and parts i would have return and go back to a standard tank. overall disappointing
