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 EZ models can each vent using dual- 2 or 3 inch single-pipe (PVC or CPVC) as well as 2-inch Flex, which can be fed through the existing B-Vent — again saving time and material. (Note: The choice of a single-pipe versus a dual-pipe configuration will depend on the air quality of the particular application.) In another first, multiple-unit installations for very large applications can reduce costs through common venting (coming in Aug).
Both new EZ models have their hot- and cold- water connections located on top of the unit — not the bottom, like most tankless heaters. This positioning allows the flexible water lines used by the previous tank heater to be quickly and easily reconnected to the new unit.
The 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.
Inside each EZ model are two stainless steel heat exchangers that have a greater resistance to corrosion and scale buildup than other materials, thereby boosting system life.
The new patent pending AutoSnap® straight fittings are the only CSST fittings that do not require any disassembly or reassembly of the fitting to the TracPipe®CounterStrike® CSST. This greatly reduces installation difficulty and time as there are no small loose gaskets, O-rings, or retainer rings to contend with in a dark and/or cold work place environment!
AutoSnap is CSA listed and features a metal to metal cup seal without any exposed stainless steel pipebehind the new fitting.Reduced torque value and reusability all make for an optimum installer friendly fitting!
