Noritz EZTR50NG Tankless Water Heater, 50-Gallon Tank Replacement, Natural Gas

The Noritz EZTR50NG is a natural gas tankless water heater meant to replace an aging 50-gallon tank. It modulates from 18,000 to 180,000 BTU and supplies up to 9.8 GPM, enough for several fixtures at once in a typical home.

This bundle targets fast tank-to-tankless conversions. Top-mounted connections line up with the piping already in place, the 25 ft flex-vent kit runs up through an existing B-vent that is still sound, and the isolation valves ship with the heater for a tidy hookup and simpler yearly flushing.

Two stainless steel heat exchangers in a steel cabinet resist corrosion. The setpoint runs from 100°F to 140°F and activation starts around 0.5 GPM. PVC, CPVC and PP venting are all supported, and the heater can also be mounted outdoors where local code allows it.
