Bosch Highflow units are gas continuous-flow hot water systems that are suitable for 1 – 3 bathroom homes. They are compact, space-saving and easy to install.

The range offers a 6+ star energy rating, which means savings on your gas bills!

All Highflow units can be combined with optional temperature controllers, which allow you to shower at your favourite temperature every time and also to stop the hot water flow after a defined volume has been reached. This way you can fill up a bathtub and do something else in the meantime.


The Bosch Condensing Hot Water are high-efficiency systems, available in Natural or LP Gas, feature advanced condensing technology. This means that they can capture additional heat otherwise wasted via flue gases which makes them more than 90% energy efficient. Their 6+ star ratings speaks for themselves.


Why is Bosch Condensing technology so energy efficient?

  • Unlike traditional hot water systems, a Bosch Condensing unit captures heat from exhaust gas and uses it to preheat incoming cold water, making the system highly energy efficient.
  • When heat from the exhaust gas is collected within the secondary heat exchanger, condensation occurs from moisture in the exhaust gas, and the resulting water is discharged from the drain pipe as an environmentally friendly and pH-neutral emission.

Solar and Heatpump

Utilising the abundance of the Australian Sun a solar water heater or heat pump can help reduce your energy usage over time and bring your carbon emissions down too. With a gas or electric booster, you can have hot showers all year round – even when the sun doesn’t shine!

Living in Australia, it only makes sense to harness the clean, inexhaustible and free supply of energy from The Sun.

Solar hot water systems are actually very simple consisting of roof mounted collectors absorbing the suns energy which heats the water. The hot water is transferred to a dedicated storage tank ready for use. To ensure there’s always hot water for those not so sunny days, an electric or gas booster is added to the system.

Heatpump Units

Utilising the heat in the ambient air and running it through a compressor, the heat produced in this process is then used to heat water that is then stored in a tank. The heat pump has no need for roof panels or sunshine and can operate in ranges starting at -10 degrees Celsius. Heatpumps Cut up to 75% of running costs compared to Electric & LPG Gas units and lower your overall emissions as well.

Quantum, Rheem and Dux unit are some of the best heatpump brands available and are all on offer.
