Tankless Water Heater Warranties
Heat-exchanger, parts and labor coverage often have different terms, registration rules and exclusions.
Updated
Direct answer
Compare the current written warranty for the exact model. Record heat-exchanger, parts and labor periods separately, plus registration, installer, water-quality and maintenance conditions.
Coverage is not one number
A long heat-exchanger term does not mean labor or every component is covered for the same period.
Save evidence
Keep the invoice, serial number, registration confirmation, permit and maintenance record. These may be needed for a claim.
Questions people ask
Does a 15-year warranty include labor?
Not automatically. Labor is often shorter or excluded. Read each coverage section in the written warranty.
