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

Asked by: Dan
Thank you for interest in our EZ98! It does in fact have a 25 year heat exchanger warranty which is the BEST in the industry. Under the product detail it does read 25 years, but yes your are correct that our Warranty Cards is outdated and we will update this immediately. Thank you very much for bring this to our attention!

Customer Reviews

EZ Series 9.8 GPM Residential Natural Gas Hi-Efficiency Indoor/Outdoor Tankless Water Heater is rated 3.4 out of 5 by 9.
Rated 5 out of 5 by from Very happy with this purchase! After a ton of research, this unit seemed like the way to go but reading the handful of negative reviews made me VERY nervous. After installing it myself in about 10 hours (not a difficult install, just time consuming depending on your setup), I was more than happy to feel piping hot water out of the tap. A lot of people say that 120 degrees is not hot enough, mine is set at 110 and is just about perfect for nice hot showers. This unit is very quiet and high quality. Slight delay in getting hot water if it hasn't been used in a bit but that's just the way these things work if you dont have a recirc pump. Overall very happy and highly recommend!

Rated 1 out of 5 by from The heater was excellent and exactly what I was looking... The heater was excellent and exactly what I was looking for. This unit is designed for simple replacement of a standard water tank. However, the Home Depot installer wanted an absurd amount of money for the installation - almost 2 1/2 times that of replacing 2 tanks with this single unit, even though my installation was actually quite simple. Consequently I returned the unit & bought 2 - 50 gallon tanks due to installation charges. Home Depot should stop carrying tankless since none of the plumbers want to install them. Very disappointed.

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!

Terrible: constantly smells of gas, LOUD rumbling whenever water is turned on, does not produce hot enough water(even on the highest temperature setting), low water pressure, can't provide water to more than one appliance at once, water even tastes strange. Big downgrade from traditional water heater! Stick to your tank water heater.
