We just switched from a tank water heater to the tankless Bosch Therm 660 EFO Natural Gas Therm Outdoor Tankless Water Heater. We have a bath and a half and so far so good. Many people are not familiar with Bosch, but they have been making these on-demand units for decades! My parents used them while my father was stationed in Germany in the 60s. The water heats up quickly and does not run out. I am anxious to get our next utility bill to see the savings there. Meanwhile, we will be putting the extra outdoor storage space to good use now that the old water heater tank is gone!
This warranty applies to both new and factory-reconditioned AquaStar water heaters.
AquaStar water heaters warranted by Bosch 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 Water Heating 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.
If the heat exchanger fails within twelve (12) years after the original installation and operation, Bosch thermotechnology corporation will furnish a replacement heat exchanger. However, if the water heater is in an approved domestic hot water recirculation application, this heat exchanger warranty is limited to five (5) 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.
If any other part fails within two (2) years after original installation and operation, Bosch Water Heating will furnish a replacement part free of charge.
In addition to supplying the replacement part(s), Bosch Water Heating will provide ground service delivery for these parts.Expedited or upgraded shipping will be charged to the customer.
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.
This warranty will not apply:
Note: The water heater must be free of damaging scale deposits, highly mineralized / unsoftened water and not subject to gas pressures greater than those shown on the rating plate, which must not be altered, defaced or removed.
It has come to our attention that products from Bosch Water Heating are being sold through on-line auctions and other unauthorized distribution channels. We believe that in some cases there are legitimate consumers trying to sell product that they have purchased through legitimate distribution channels. However, we are finding that some of the merchandise has actually been stolen from our customers. Please be advised that our product warranty is void with respect to stolen goods. Further, we reserve the right to require a legitimate sales receipt showing that the product was purchased from one of our customers in order to provide warranty coverage.
No one is authorized to make any other warranties on behalf of Bosch Water Heating. It is expressly understood that the replacement warranty of Bosch Water Heating 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 Water Heating 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 Water Heating's sole liability with respect to any defect shall be for the replacement of 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.
