Noritz has revolutionized the game with the new EZTR40, providing a direct tankless replacement for 40 and sometimes 50-gallon tanks. This cutting-edge solution can be installed in the same time as a traditional tank water heater, making it a convenient choice. With upcoming NAECA regulations changing the dimensions of traditional tanks, our top mount water connections, ½ gas line, and the ability to vent directly through existing B-Vent make retrofits a breeze.

The EZTR40 simplifies the process with flexible venting that connects directly to existing B-Vent, eliminating the need to spend time changing the existing vent. Water connections on the top of the heater allow for the use of flex lines, just like with a tank. The 1/2-inch gas line connection to the existing line saves both time and money.

Designed to easily convert your 30/40-gallon tank water heater to tankless technology, the EZTR40-LP from Noritz is the next step in the tankless revolution. It delivers a flow rate of up to 6.6 gallons per minute and is Energy Star listed. With its durable steel casing and polyester coating, this indoor space-saving water heater incorporates high-efficiency condensing technology. The package includes a flexible vent kit and an isolation valve kit.

Installation is a breeze with a minimum of 15,000 BTU and a maximum of 120,000 BTU. The user-friendly control panel allows for easy temperature adjustment to suit personal comfort. Crafted with exceptional quality, this water heater is a must-have for homeowners looking to save on energy costs. Backed by a 5-year parts warranty and a 12-year heat exchanger warranty, it is designed for residential use. Upgrade your water heating game and choose Noritz for efficiency, durability, and unmatched performance.
