Product warranties are calculated from the date of purchase or, in the case of a newly constructed home, the first date of occupancy. Rinnai encourages registering your product. Product registrations serve as proof of purchase as well as well as giving you access to product updates and notifications. If the product has not been registered, you will be given the default warranty page and an opportunity to register your product. Please note that registrations could take up to 2 business days AFTER online registration to be displayed in the product warranty lookup feature.
Rinnai offers optional extended, limited warranty labor coverage on select models of tankless water heaters. Register within 30 days for the optional extended labor coverage. Some restrictions apply, view Product Warranty details form more information.
