This warranty applies to both new and factory-reconditioned AquaStar water heaters.

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.
