Noritz EZTR75-LP Condensing Tankless Water Heater, 75-Gal Replacement, Propane

The Noritz EZTR75-LP is a residential condensing tankless water heater for propane homes, sized to stand in for a 75-gallon tank. It reaches 199,000 BTU and up to 11.1 GPM, with a 0.96 UEF rating for efficient whole-house hot water.

Primary and secondary heat exchangers are made of 316L austenitic stainless steel, and condensing operation recovers extra heat from the exhaust. A non-return valve guards against backflow. Top water connections remove extra piping, and a 2 in. flex vent can run up through an existing B-vent for a direct tank replacement.

The display offers presets of 120°F, 130°F and 140°F, and a remote thermostat fine-tunes output anywhere from 100°F to 140°F. Wi-Fi compatibility, a flame sensor, overheat prevention, lightning protection and freeze protection round out the package.
