Instant Gas Hot Water Heater Systems

Rinnai revolutionised the Australian water heating market in the early 90’s when it launched the first fully electronic gas Continuous Flow hot water heater system. Appropriately named the Rinnai INFINITY because it never runs out of hot water. Today hot water heater systems are even more sophisticated – designed with the environment in mind with low emission burners, high energy efficiencies and low flow rates, compatible with water saving outlets and showers.

Solar Gas Pump

Solar Heat Pump Hot Water Systems

Hot water heater systems of the future are here today and we are the experts when it comes to advice and installation.

What is the Quantum heat pump?

Quantum heat pump is a patented system whereby heat from the ambient air is absorbed by an environmentally friendly refrigerant in the evaporator. This refrigerant gas is then compressed which causes the gas’s temperature and pressure to be raised.

This hot gas is passed through tubes wrapped around the outside of the water tank as the condenser. Heat is then transferred from the tubes to the water inside the tank. Once the heat from the compressed gas has been transferred to the water in the tank, the gas changes state as it has transferred it’s heat to water.

This cooled gas then passes through an expansion device (TX valve) and back to the evaporator. The cycle is then repeated until the water in the storage tank reaches the set temperature. The Quantum heat pump’s efficiency stems from the fact that only minimal electricity is required for the compressor, fan and digital display panel.

What is the Heat Pump Suitable For?

It works in temperatures from as low as -10°C up to 40°C both day and night very efficiently without the need for boosting, and only Quantum can do that! The Heat Pump principle is simple and can be compared to a refrigerator, but in reverse. It extracts latent energy from the air and transfers it to the heating system.

A Water Heater that is Environmentally Friendly

This free energy from the environment is converted into useful heat to heat water. In other words, you are using free energy from the environment that doesn’t cost a cent, and at the same time reducing your carbon footprint. Download our brochure.


Sanden Hot Water Systems and Energy Costs

case_study_tableIn Australia we pay more for electricity than most places in the developed world, and it’s no wonder. With the recent introduction of the carbon tax, combined with the building of new electricity infrastructure, many commentators suggest that this could result in soaring electricity costs for consumers.

Because traditional hot water systems contribute to a significant portion of a household’s energy costs, taking control of the situation starts with seeking the most efficient hot water system on the market.

Energy Savings with the Sanden Hot Water Heat Pump System

A Sanden Hot Water Heat Pump uses industry-leading technology found in refrigeration and air conditioning units, where energy is drawn in from the ambient atmosphere and transferred into heat. An Ozone friendly refrigerant R744 (CO2) absorbs the heat, which then flows into a compressor where it’s converted into a high-temperature gas. Then, it passes through a condenser within the water tank and the water is heated up. No backup elements are required.

The result is a system that requires radically less electricity to heat water when compared to conventional hot water systems. In fact, the initiative will save up to 78 per cent on a hot water bill, year after year. And no, it doesn’t involve cold showers!

Environmentally Friendly Hot Water

As an environmentally advanced product, it is also affordable. The system is ranked alongside solar energy in terms of environmental friendliness and as such it is eligible for rebates and other government incentives. It offers the highest level of Small scale Technology Certificates (STCs) of any hot water heat pump system, saving you hundreds at the outset.
