What You Need to Know About the Rinnai Extended Warranty

Last updated 5 years ago

Buying a Rinnai tankless water heater will reduce your energy bill and increase your supply of hot water. A new Rinnai tankless water heater will also last up to twice as long as a conventional water heater. Furthermore, you’ll enjoy the peace of mind of Rinnai’s Extended Warranty coverage. Learn more about what Rinnai’s Extended Warranty covers and why it provides you with unmatchable peace of mind.

Obtaining Extended Warranty Coverage

If you have recently ordered a Rinnai tankless water heater in the Value, Luxury, or Ultra series, or if will be ordering one soon, you must register within 30 days of purchase or new home occupancy to be eligible for the extended warranty. This can be done online or over the phone, and serves as your proof of purchase, which allows you to receive extended warranty coverage.

Residential Terms of Coverage

Luxury and Ultra Series Rinnai tankless water heaters used for residential applications come with labor and parts warranty coverage for up to five years from the date of purchase. The heat exchanger is covered for 12 years if used for water heating, and 10 years if used for water- and space-heating purposes. Value Series Rinnai tankless water heaters will have labor warranty coverage for one year and parts coverage for five years. Heat exchanger coverage lasts for 12 years if the water heater is installed with a tankless isolation valve kit; otherwise, coverage is for a 10-year period.

Commercial Terms of Coverage

If you are buying a Luxury or Ultra Series Rinnai tankless water heater for commercial purposes, you will have five years of warranty coverage for the heat exchanger and for all other parts and components, and one year of labor coverage. Value Series Rinnai tankless water heaters do not come with warranty coverage if used for commercial applications.
