Bosch OptiFlow NG Tankless Hot Water Heater 26L

The Bosch OptiFlow is redefining the modern 6 star continuous flow hot water system. Through the application of patented Bosch technologies, the OptiFlow achieves optimum performance throughout its lifetime by intelligently and continuously adapting to its environment.

The combustion management system utilises a patented algorithm, measuring the gas to air ratio 4 times per second and adjusting the gas valve and fan speed to ensure optimum combustion. This ongoing process ensures the appliance is able to adapt to changing environmental conditions throughout its lifetime.

Our patented “Easy Minimum” technology allows the OptiFlow hot water system to operate at very low minimum power output, while maintaining a stable output temperature for more comfortable showers. In this situation the appliance burner modulates in conjunction with an active by-pass valve. This feature extends the operating range of continuous flow water heater technology.
