FOR IMMEDIATE RELEASE
Noritz Extends 12-Year/6,500-Hour Warranty To
Tankless Water Heaters in Controlled Recirculation Systems
------------------------------------------------------------------------------------------------------------
Eligible Noritz models all feature a commercial-grade heat exchanger that recently
demonstrated superior durability in head-to-head tests with rival tankless models
FOUNTAIN VALLEY, CA (September 22, 2010) — Tankless water heater manufacturer
Noritz America recently extended its 12-year/6,500-hour warranty to residential models
used with controlled recirculation systems that deliver hot water more quickly to the tap.
The extension applies to all Noritz residential tankless water heater products that feature
the company's durable, commercial-grade heat exchanger. Included are the new NR83-
DVC concentric tankless water heater, which made its debut this month, as well as the
NR98, NRC111 and NR111.
"Twelve years typically translates into roughly 1.5 hours of water heater combustion per
day," explains Bob Hitchner, Senior Vice President - Sales, Marketing & Business
Development for Noritz. "A residential system that circulates warm water for a couple of
hours in the morning and another couple of hours in the evening should make it for the
full 12 years."
To qualify for protection under the new residential recirculation warranty, a Noritz
tankless water heater must meet the following key stipulations:
 The unit must have been installed on or after September 1, 2010, and equipped with a
controlled recirculation pump system that has been installed in accordance with the
Noritz Installation Manual.
 Water heater operational time must not exceed 12 years, or 6,500 hours, whichever
comes first. (Note: Operational hours are the hours of actual usage, as counted and
stored in the water heater controller.)
 The recirculation pump must be controlled by an aquastat, which activates the pump
when the water temperature falls below a minimum set point and deactivates it when
the water temperature reaches the maximum set point.
Noritz also strongly recommends the usage of demand-type timers and sensors to confine
pump activation to peak usage periods, further reducing the load on the water heater.
