Daikin CO2 Heat Pump Hot Water System

Daikin combines energy-efficient heat pump technology with R744 CO₂ refrigerant to provide hot water without relying on traditional gas heating or a conventional electric storage system. The system captures heat from the surrounding air and transfers that energy into your water, helping reduce the amount of electricity required for everyday hot water.

Daikin states that its CO₂ heat pump technology can achieve efficiencies of up to six times that of traditional electric or gas water heaters. Because much of the energy used to heat the water is drawn from the surrounding air, considerably less electricity can be required than with conventional electric water heating.

Potentially, yes. Daikin states that its heat pump hot water technology can use up to 77% less electricity than an equivalent electric water heater under specified conditions. Your actual savings will vary depending on hot water usage, electricity rates, household size, system settings and whether you have solar.

Yes. If you're replacing gas ducted heating with an electric reverse cycle ducted system, it's a great opportunity to also consider replacing your gas hot water system with a Daikin CO₂ Heat Pump.

Dale Air can provide your heating, cooling and heat pump hot water as part of the same home electrification project, helping you reduce your reliance on gas and move towards a more energy-efficient, all-electric home.

The Daikin system uses R744, commonly known as CO₂, as its refrigerant. R744 has a Global Warming Potential of 1, making it a lower-impact refrigerant choice while also being particularly well suited to producing high-temperature hot water.

Panasonic's CO₂ Heat Pump uses a split-system design, with the outdoor heat pump separate from the hot water storage tank.

The outdoor unit operates at just 37dB, providing exceptionally quiet operation. The split design also gives Dale Air greater flexibility when positioning the outdoor unit to help minimise noise around bedrooms, living areas and neighbouring properties.

Yes. Replacing gas hot water with a heat pump is one way to reduce your home's reliance on gas. For households considering broader electrification, Dale Air can also combine heat pump hot water with efficient reverse-cycle heating and cooling to help transition more of the home to electricity.

Yes. Heat pumps don't require warm weather to operate. They extract available heat energy from the outdoor air, including during colder conditions, making them suitable for year-round hot water in Melbourne's variable climate.

Eligible Victorian households may be able to access government incentives when replacing an existing gas or electric hot water system with an approved energy-efficient heat pump.

Eligibility and available incentives depend on your existing system and current program requirements. Dale Air can help you understand which incentives may apply to your installation.

Quiet operation is one of the advantages of the Daikin CO₂ Heat Pump Hot Water System. Designed specifically for residential use, the compact outdoor unit operates discreetly in the background while providing your home's hot water.
