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

11.1 GPM EZ Series Natural Gas Hi-Efficiency Indoor/Outdoor Tankless Water Heater is rated 5.0 out of 5 by 4.

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.

The EZ style with fittings on top makes the installation a snap when swapping out a conventional water heater. Performance is outstanding! Water pressure is great and no appreciable difference in the length of time to receive hot water at the tap. I did need to cut the feed lines but used “shark bite” fittings which were a breeze! I highly recommend the EZ products by Noritz if you are doing a self install!

After 3 damaged heaters received one that works(only small area on top of unit where paint rubbed off)Unit works great ,Quiet ,endless hot water, exhaust temp. very low (every penny of gas goes into water.) Not very hard to install saved a lot of money doing it myself.
