Obsolete Bosch 125BO NG (Natural Gas) Outdoor Tankless Water Heater

Global Protankless Supply currently has 1 of the Bosch Aquastar 125BO NG outdoor tankless water heaters left in stock. The Bosch AquaStar 125 BO model has a pilot light and offers a Piezo push-button ignition and utilizes a modulating gas valve to ensure a constant temperature at varying flow rates. The 125BO is designed to be installed outdoors and has a 120V plug that is only used for freeze protection. The 125 BO is the perfect tankless solution for smaller families and households that only use no more than two hot water applications at a time.
The Bosch 125BO NG is a good replacement for the older GWH 425HNO NG also.  The 425HNO NG was basically the same unit but the 125BO has the standing pilot light and the 425HNO NG used the hydro ignition system.

Bosch has approved these four outdoor heaters for the following areas of the United States:

Florida, Georgia, North Carolina, South Carolina, Alabama, Mississippi, Arkansas, Texas, Virginia (only in zip codes beginning with the first three digits 233-237), Arizona (in zip codes beginning with the first three digits 850-857 and 864), Oregon (in zip codes beginning with the first three digits 970-975), Washington (in zip codes beginning with the first three digits 980-986), California (except in zip codes beginning with the first three digits 935 or 961).

Some people install these outdoor tankless water heaters for their summer homes or cabins in areas of the US and Canada that do freeze. When these heaters are installed in freezing locations the water heaters must be completely drained so that the heat exchanger and pipes do not burst. The Bosch warranty does not cover damage due to freezing.

The WebStone Isolation Valve Kits really make the task of draining these outdoor tankless water heaters easy, so they are especially recommended for this application.
