Bosch Exclusive Design for Scale Prevention
Bosch’s patented heat exchangers offer dual-fan and fully modulating vertical burner design to achieve an “even” flame pattern, preventing hot-spots and corrosion common with other tankless water heater burner designs. Bosch’s proprietary built-in turbulators help to prevent scale build-up that can reduce operating efficiency, allowing Bosch tankless water heater to work efficiently and last longer.

Gas Version:

Gas Condensing Technology

Bosch condensing gas tankless water heaters are ultra efficient systems. Unlike traditional non-condensing water heaters, a condensing unit captures latent condensation heat from exhaust gas and uses it to preheat the incoming cold water, making Bosch condensing tankless water heaters 10% more efficient than a traditional tankless water heater.
