  • Warranty

    General
    BOSCH gas tankless water heaters are warranted by the Manufacturer (BOSCH) through Bosch Thermotechnology Corp. Bosch Thermotechnology Corp. will furnish a replacement heat exchanger and will furnish a replacement of any other part which fails in normal use and service within the applicable periods specified below, in accordance with the terms of this warranty. The Bosch Thermotechnology Corp. replacement will be warranted for the unexpired portion of the original warranty. This warranty will be valid only for water heaters in possession of the original purchaser as recorded on the warranty card.

    The Heat Exchanger
    If the heat exchanger fails within Fifteen (15) years after the original installation and operation, Bosch Thermotechnology Corp. will furnish a replacement heat exchanger. However, if the water heater is used within an approved hot water recirculation and supplied with circulated water, this heat exchanger warranty is limited to three (3) years from date of original installation and operation. If the water heater is installed in other than a single family dwelling, this heat exchanger warranty is limited to two (2) years from date of original installation and operation.

    Exceptions
    This warranty will not apply:
    1. to defects or malfunctions resulting from failure to properly install, operate or maintain the unit in accordance with the printed instructions provided;
    2. to damage or abuse, accident, neglect or freezing and other acts of nature;
    3. to damage resulting from operation with either the flame sensor rod or overheat sensor removed;
    4. to failure of the heat exchanger resulting from the operation of the water heater in a corrosive atmosphere or at water temperatures exceeding the maximum rating, or if the water heater is not supplied with potable water;
    5. to defects or damage cause by any attachment or modification, including any energy-saving device;
    6. to damage resulting from scale deposits and/or highly mineralized / unsoftened water supply.

    All Other Parts
    If any other part fails within five (5) years after original installation and operation, Bosch Thermotechnology Corp. will furnish a replacement part free of charge.

    Service Labor Costs
    This warranty does not cover any labor costs associated with service, removal or re-installation of part(s). All such costs must be borne by the purchaser.

    Additionally, this warranty does not cover any labor costs associated with service, removal, installation or re-installation of the original water heater or a replaced water heater.

    How to Make a Claim
    Any claim for warranty parts should be made to your local dealer or distributor:

    BOSCH THERMOTECHNOLOGY CORP.
    50 Wentworth Avenue
    Londonderry, NH 03053
    Tel. 866-330-2730
    www.bosch-climate.us

    In most cases, the dealer or distributor will be able to promptly honor your claim and subsequently notify Bosch Thermotechnology Corp.. However, all replacements are made subject to validation by Bosch Thermotechnology Corp. of in-warranty coverage. The damaged or defective item must be made available in exchange for the replacement.

    Miscellaneous
    No one is authorized to make any other warranties on behalf of Bosch Thermotechnology Corp.. It is expressly understood that the replacement warranty of Bosch Thermotechnology Corp. shall be in lieu of any and all other warranties, express or implied, including warranties of merchantability or fitness for a particular use or purpose, and further that Bosch Thermotechnology Corp. shall not be liable for any loss or damage directly or indirectly arising from the use of the hot water heater, or for any consequential damages arising from such use (including damages from water leakage). Bosch Thermotechnology Corp. sole liability with respect to any defect shall be for the replacement of the defective part(s). Some states do not allow such limitations and exclusions, so the above may not apply to you.

    This warranty gives specific legal rights. You may also have other rights which vary from state to state.
