The Bosch Optiflow Professional is a gas-powered, 6-star energy rated continuous flow hot water system which comes in 16L, 20L and 26L varieties. 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.
