Included are the new NR83-DVC concentric tankless water heater, which made its debut this month, as well as theNR98, NRC111 and NR111.“Twelve years typically translates into roughly 1.5 hours of water heater combustion perday,” explains Bob Hitchner, Senior Vice President - Sales, Marketing & BusinessDevelopment for Noritz. “A residential system that circulates warm water for a couple ofhours in the morning and another couple of hours in the evening should make it for thefull 12 years.”To qualify for protection under the new residential recirculation warranty, a Noritztankless water heater must meet the following key stipulations: The unit must have been installed on or after September 1, 2010, and equipped with acontrolled recirculation pump system that has been installed in accordance with theNoritz Installation Manual. Water heater operational time must not exceed 12 years, or 6,500 hours, whichevercomes first. (Note: Operational hours are the hours of actual usage, as counted andstored in the water heater controller.) The recirculation pump must be controlled by an aquastat, which activates the pumpwhen the water temperature falls below a minimum set point and deactivates it whenthe water temperature reaches the maximum set point.Noritz also strongly recommends the usage of demand-type timers and sensors to confinepump activation to peak usage periods, further reducing the load on the water heater.-more-
