With storage tanks available from 25L through to 400L a Flowmaster Rinnai hot water heater is suited to small units or large family homes. Running on mains pressure you are guaranteed to have the highest water pressure flow rate possible.

All Rinnai Flowmaster hot water tanks are built to last, coming with inbuilt anode protection and pressure temperature relief valves as standard, with all units being backed by a high 7 year Australian wide warranty*.

Rinnai Gas Mains Pressure Storage

The Rinnai hot water HOTFLO gas mains pressure storage heaters are available in two sizes – 135L and 170L. With a HOTFLO Rinnai hot water heater you will have a strong, constant flow of hot water with no lack in pressure when multiple fixtures are used simultaneously.

For extra durability these hot water storage tanks are comprised of vitreous enamel lined steel and include a pressure temperature relief valve and safety shut off valve.

Rinnai Solar Powered Hot Water Heaters

If you are looking for “The Rolls Royce of solar hot water systems” you can’t go past the Rinnai hot water Prestige Range. This high quality hot water heater is comprised of a 444 grade stainless steel tank with TiNOX technology on its excelsior collectors. This technology allows the solar collectors to gain the maximum absorbency from the sun’s rays. The tanks sizes range from 180L – 330L.

Rinnai also offers the Sunmaster range of solar powered hot water heaters with their tanks being comprised of vitreous enamel available in tank sizes of 175L – 330L.

Both options are available as a close coupled, roof mounted, system with flat plate or evacuated tube systems.

All of Rinnai’s solar powered hot water heaters are available with either electric or continuous flow gas boosters to ensure hot water 24/7.

Rinnai Solar Gas Boosters

Couple your solar powered hot water heater with a Rinnai solar booster to ensure you will have hot water 24/7 – even during weeks of cloudy days.

Rinnai Heat Pumps

A heat pump is an excellent alternative to a solar powered hot water heater (if you don’t have the correct roof access) or as a replacement for an electric hot water heater.

The Rinnai hot water range of heat pumps are extremely energy efficient and can save you up to a 25% reduction on your water bills, compared to an electric storage system.

Rather than absorbing energy from the sun a Rinnai hot water heat pump draws energy from the outside ambient air – working in much the same way as a refrigerator, but in reverse. There are two models available – HOTFLO Split Heat Pump and the HOTFLO Integrated Heat pump.
