Tankless gas water heater OEM Rinnai Corp. has extended the heat exchanger warranty from 3 years to 12 years on several condensing tankless water heaters used in recirculating applications.
The extended warranties apply to models RC98HPe, RC98HPi, RC80HPe, and RC80HPi, and the new warranty pertains to recirculating systems that are controlled through an aquastat/thermostat, a timer, or an on-demand system.
The change means that the company's condensing tankless products used in recirculating systems will now have the same 12-year heat exchanger warranty as all residential installations.
“We originally implemented a reduced heat exchanger warranty on condensing units in recirculating systems due to the accelerated wear that results from use with a constantly running circulation loop,” said Joe Holliday, Rinnai’s director of product management. “However, we realize that advances in some recirculating systems have eliminated the need for constant recirculation. This, along with advances in the strength and durability of our heat exchanger design, allows us to offer the same warranty as traditional residential installations.”
The warranty change is effective immediately on all new Rinnai brand condensing tankless unit installations with qualified recirculation systems and is not retroactive.
