With sleek curves on the outside and innovative technology on the inside, the OptiFlow is the perfect hot water system for the modern home. It’s the latest innovation in hot water from Bosch.

The Bosch OptiFlow Bluetooth Hot Water Units are an instantaneous gas hot water system suitable for 1 - 3 bathroom homes. They are compact space saving and easy to install!

It’s the latest innovation in hot water from Bosch. The whole range offers a 6 star energy rating, which means savings on your gas bills!

All models can be combined with optional temperature controllers, which allow you to shower at your favourite temperature every time.

These models of the Bosch continuous flow hot water systems have been specifically designed for superior quality, high energy efficiency and ease of installation for your building projects. Whether building a new home, or replacing an existing hot water system as part of a renovation, a Bosch OptioFlow is the perfect option!


For Android and iOS, the separate user app transforms consumers smartphones into a controller. They can adjust the temperature, track energy and water usage, and keep an eye on costs, giving them more control with fewer controllers.


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.

Combustion Management

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.

Minimum Power Technology

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.
