The EZ Series of high-efficiency, condensing tankless water heaters from Noritz America Corp. are designed to cut installation time and cost when replacing larger, storage tank-type units. The ENERGY STAR-rated EZ98-DV and EZ111-DV 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. 714/433-2905; www.noritz.com.
