Ariston (Point of Use) Warranty 6 Year Warranty

This warranty applies to both new and factory-reconditioned Ariston (Point of Use) water heaters.


  1. The Inner Tank — If the inner tank leaks within six (6) years from the date of original installation of the water heater, because of a defect in material or workmanship, Bosch Water Heating will furnish to such Owner a new heater of the then prevailing comparable model.
  2. Any Component Other than The Inner Tank — If any other component part (other than the inner tank) proves to be defective in material or workmanship within one (1) year from the date of original installation of the water heater, Bosch Water Heating will furnish the Owner with a replacement of the defective part(s).
  3. Verification of Date of Original Installation — When Owner cannot verify or document the original date of installation, the warranty period begins on the date of manufacture marked on the tag affixed to the water heater.


  1. This Limited Warranty shall be the exclusive warranty made by the Manufacturer and is made in lieu of all other warranties, expressed or implied (whether written or oral), including, but not limited to, warranties of merchantability and fitness for a particular purpose.
  2. Manufacturer shall not be liable for any incidental, consequential, special or contingent damages or expenses arising, directly or indirectly, from any defect in the water heater or the use of the water heater.
  3. Manufacturer shall not be liable for any water damage arising, directly or indirectly, from any defect in the water heater component part(s) or from its use.
  4. Manufacturer shall not be liable under this warranty if:
    • The water heater or any of its component parts has been subject to misuse, alteration, neglect or accident, or
    • The water heater has not been installed in accordance with the applicable local plumbing and/or building code(s) and/or regulation(s), or
    • The water heater has not been installed in accordance with the printed manufacturer's instructions, or

Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you. This warranty gives you specific legal rights and you may also have other rights which may vary from state to state.


Note: A water heater should be installed in such a manner that if it should leak, the resulting flow of water will not cause damage to the area in which it is installed.
