The EZ Series of high-efficiency, condensing tankless water heaters from Noritz America cuts installation time and cost when replacing larger, storage tank-type units, it notes. 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, Noritz says.
