Noritz EZ Series Pro EZ98DV Tankless Water Heater, 180,000 BTU, NG or LP

The Noritz EZ98DV from the EZ Series Pro line is a 180,000 BTU tankless water heater rated at up to 9.8 GPM. It is set up for natural gas out of the box and comes with a kit for switching to liquid propane, so it suits homes on either fuel and installs indoors or outdoors.

Two high-grade stainless steel heat exchangers hold up against corrosion and scale, and the unit carries a 0.98 UEF rating. Bluetooth gives the owner or installer control over temperature, pump timers and dipswitch settings, and it shortens the startup procedure, while an on-board display reports temperature, status and error codes.

Water lines attach at the top, so existing lines can be reconnected faster. Venting is flexible, with support for direct, single, Flex Vent, No Roof Kit and outdoor setups. A Steady BTU mode drops effective output below 5K BTU when incoming water is warm in summer, keeping outlet temperature stable.
