The Bosch Optiflow is a gas-powered, 6-star energy rated continuous flow hot water system

Bosch’s Optiflow combustion management system utilizes a patented algorithm to modulate the appliance gas valve and fan speed to ensure optimum combustion. The gas to air ratio is measured 4 times per second, and if necessary adjusted. This process is ongoing over the lifetime of the appliance, allowing it to intelligently and continuously adapt to changing environmental conditions, ensuring optimum efficiency in all conditions over the lifetime of the appliance. A new patented Bosch technology known as “Easy Minimum” allows the Optiflow hot water system to operate at very low minimum power output, while maintaining a stable output temperature for more comfortable showers.
