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

Can this be installed in the attic? I have a tank water heater in the attic that i need to replace.
Asked by: HarryV
It heats water. If you put cold water in, you get hot water out. It doesn't care where in the house you put it as long as it has water, gas/electricity, and proper venting.

Answers Is this enough to run 3 showers at the same time? I have a 4 bathroom 2,900sqft house and 5 women's plus me.

Asked by: Esgardo
Yes, at 11.5 gallons per minute it should be since most showers are around 2.5 gallons per minute.

Can the exhaust be vented through the roof and the intake be vented through the side wall?

Can the exhaust be vented through the roof and the intake be vented through the side wall?
Asked by: stephen
Yes, just be sure your DIP switch settings are correct. Don't have manual handy but you'll set DIP switch for same as interior air setting in manual. Basically it tells the heater air is coming from different air pressure locations. If this is attic installation you can bring intake out of attic and not go through side wall with this same DIP setting

Noritz EZ Series 11.1 GPM Residential Natural Gas Hi-Efficiency Indoor/Outdoor Tankless Water Heater is rated 4.5 out of 5 by 20.
Rated 5 out of 5 by from This unit is Great, plug and play. This is a... This unit is Great, plug and play. This is a do it your self. Buy the 3/4" valve kits with the relief valve, and new 3/4" flexes metal hoses. Buy the 2" x 4" PVC 90 elbow with grill for the fresh air intake. Buy 2" x 4" con. red. for the exhaust connection on the unit, also buy a couple of 4" duct fitting for exhaust connection to existing. 3 hours to demo old, install new and pipe up. The only new line you have to run is the 1/2" condensate line to out side, buy shark bite fitting and 1/2" copper pipe. Use the existing 1/2" Gas line, after the wall step it up to 3/4" and connect to unit. Tie the relief to existing. Hook flex metal hose to house connections. I did cap off the recirculating line to allow 25 years. The only bad thing is it takes the hot water to reach the farthest point 1 min instead of 25 sec. I have a 4200 sq. ft. house. i use 2 shower a dish washer and 2 sinks at the same time and the Nort. keeps up. I had a 2 plumbing companies give me quote over $4,500 plus, I told them I am not paying there Ferrari payment.

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!

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!

The other one lasted for 15 years! This one seems to be a big design improvement, if that's possible. The connections are on the top, so less plumbing and the burner is so efficient, it doesn't need to be vented through the chimney. It's also the only one on the market with a 25 year warranty. Highly recommended.
