WARRANTY COVERAGE
First Ten Years –Limited Warranty

Bosch Thermotechnology Corp. (BTC) warrants that the Tank assembly will remain free of leaks for ten years from the date of original installation provided that the Tank is properly maintained by a qualified heating contractor and the other conditions of this warranty are met. If during this time BTC determines that the leak is the result of a defect in workmanship or materials, BTC, at its option, will repair or replace the Tank. Labor charges are not included.

Eleventh Year and Beyond– Limited Warranty

Beginning on the eleventh year from the date of original installation and thereafter, BTC provides a limited prorated warranty for defects in the Tank. If BTC determines that the leak is the result of a defect in workmanship or materials BTC will, at its option, repair the defective Tank or replace it with the most comparable model available from BTC at the time of the replacement, provided that the purchaser pays for the proportionate charge set forth below. The proportionate charge is based on the current list price of the Tank involved in the warranty claim (or the nearest comparable model). The purchaser is charged a percentage of the list price of the Tank (at the time of the claim) as detailed below.

If the Tank is no longer available, BTC will provide a new residential hot water Tank at the then applicable retail price less the proportionate charge for the Tank as set forth in the table above (the charge will be calculated using the last list price of the discontinued Tank). Labor charges are not included.

Other Hot Water System Components

All other components outside of the indirect tank will be covered for 1 year from date of installation.

Please be aware there are many factors and elements that affect the Bosch SST units.  One major factor that is not covered under the lifetime limited warranty is high levels of Chlorine in the water.  BTC will not warranty a unit that is installed in an area that has 80 parts per million (ppm) or higher of Chlorine in the water.  People with high levels of Chlorine or other minerals in the water should use a glass lined indirect tank and at current this is not an option through Bosch.

Changes to Bosch Therm Gas Tankless Water Heaters

Bosch is always upgrading their products and coming out with new and better models and changes.  Below are a few new changes to the Bosch Therm gas tankless water heaters.

The current silver-gray cover will be changing to Bosch white. This change is consistent with the Bosch residential product visual branding, such as with Greenstar, Greensource, Greentherm, and Therm.  Once the inventory of the units with silver covers is sold then Bosch will start changing over to the new white covers.

This warranty statement takes affect with products produced since April 2014 (FD 420). C950ES, C1050ES, and C1210ES products produced prior to April 2014 (before FD 420) will follow the previous warranty statement.

Using Bosch Tankless for Domestic Hot Water Recirculation

Bosch tankless water heaters can be used in recirculation applications and there are many different set ups for this such as direct recirculation and indirect recirculation.  Certain models of the Bosch tankless water heaters are approved for direct recirculation and are listed below.  Please be aware that the heat exchanger warranty of 15 years will be reduced to 3 years for direct recirculation.  This is stated in the warranty section of the installation manual.   All of the Bosch tankless water heaters can be set up for an indirect recirculation application in conjunction with a mini tank, recirculation pump and aquastat as described in the image below. The warranty for recirculation through an indirect mini-tank and not directly through the heater is 15 years.

Bosch tankless water heaters approved for direct recirculation:
Bosch Therm C1210ES
Bosch Therm C1210ESC (Commercial Unit)
Bosch Greentherm C1050
Bosch Greentherm C950
Bosch Therm 940ES
