Noritz’s EZ Series of high-efficiency condensing tankless water heaters are engineered expressly for the North American residential market. They 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. Both models include top-mount water connections, maximum venting flexibility, and the possibility of reusing the existing tank unit’s half-inch gas line. The EZ98-DV and EZ111-DV are also available in bundle packages (EZTR50 and EZTR75, respectively) that include materials and accessories for direct indoor replacement of 50- and 75-gallon tank-type water heaters.
