Bosch AquaStar Model 125 FX
Built by Bosch, the Aqua Star 125 FX is the same great heater as the
125HX - but with a built in power vent. This model uses a standard
plug for the power vent and electronic ignition. If you
need an AquaStar and want to vent out through a side wall - then
this is the heater for you! And just like the 125HX - the 125FX
uses no energy when idle, the 125FX has an energy factor of .80 the average
storage tank heater has an energy factor of just .59. This instantaneous hot water tank is available in
both gas tankless hot water heater and propane water heater.
Please Note: The Bosch Aquastar 125FX can only be vented horizontally
- so it must be vented through an outside wall
and requires an outside terminator (vent hood). Also the 125FX should have a back flow preventer for areas where temperatures
fall below 32 degrees. See the link below for the optional FXHOOD. ZVent venting
products will work with the AquaStar 125FX too (click here

Aqua Star Model 125 HX
Robert Bosch, Inc., developed the 125HX patented hydro-generated ignition system
that requires no standing pilot, electricity, or batteries. The Aquastar 125HX
is the first tankless natural gas water heater to use this technology for pilot
ignition. Hydro-generated ignition works much like the giant turbines in a
hydroelectric dam using the flow of water to generate electricity. When a hot
water tap is opened, cold water flows through the 125HX's hydro generator. The
flowing water spins a tiny turbine, which, in turn, instantly produces electricity.
This electricity creates the spark required to light the burners and the water is
then heated as it passes through a copper heat exchanger. Choose the 125HX in
either LP water heater or natural gas water heater.
This heater has been replaced by the new Bosch 1600H
This hydro-generated technology produces multiple important benefits:
- Eliminates the need for any additional energy source. Only flowing water and gas are required
- Uses energy only when you call for hot water - 82% efficiency
- Eliminates worries about dead batteries and the need to constantly change batteries
- Simplifies installation dramatically by eliminating the need for an electrical connection
