    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.
