Every day the ground absorbs approximately half of the sun’s energy that reaches earth and stores it at a steady temperature at specific depths. Rinnai’s Geoflo Hybrid²² Geothermal system harnesses this free renewable energy source from the ground to reliably deliver highly efficient energy boosting to your home’s heating and cooling needs.
In addition to heating and cooling, the Geoflo Hybrid²² technology diverts surplus energy to the generation of essentially free hot water for your home.
Renewable Clean Energy
Geothermal energy is extremely affordable and can assist to cut electricity consumption by up to 50 percent in comparison to a traditional ducted reverse cycle inverter air conditioning system. Geothermal system heating and cooling performance is maintained during extreme climate conditions eliminating high seasonal energy costs.
Rinnai’s Geoflo system is an incredibly quiet and efficient way to heat and cool your premises and deliver your hot water needs. Because the stable temperature of the Earth is used, you can sustainably reduce your heating and cooling running costs by up to 50 percent. Best of all, geothermal systems can be installed in a wide variety of home or business applications in virtually any location.
When looking for a heating and cooling system that is virtually noise free, look no further than geothermal. The reduction in moving parts and high noise generating components in the Rinnai Geoflo Hybrid22, delivers smooth quiet operation, devoid of the higher Db noise levels of older technologies. That keeps neighbours and families comfortable and renders the environment more peaceful.
Geothermal heat pump systems are designed with the user in mind. They are designed to be installed in either new or retrofit applications. And since the hardware requires considerably less space than traditional HVAC systems and ancillary equipment, you can instantly save storage footprint in your home by switching to a geothermal system.
Geothermal systems have a relatively low level of moving parts. With high durability and reliability geothermal systems are becoming the way of the future for many homeowners who want low energy costs and environmental solutions that deliver greener outcomes.
Works in any climate
Rinnai’s Geoflo Hybrid22 is a highly efficient hybrid geothermal system that uses free energy from the ground to transfer energy to the warm or cold air into all homes and buildings as well as generating essentially free domestic hot water. Conventional heat pumps heat room air and hot water very slowly when outside air temperatures are low, below around 10°C and down to as low as -5°C, as in cold nights and winter conditions. However, irrespective of the outside temperature, the Rinnai Geoflo Hybrid22 heats your room and heats your hot water rapidly because the ground temperature is always at a high stable 17°C. This provides a higher COP (coefficient of performance) and a higher thermodynamic efficiency than conventional reverse cycle inverter systems and heat pumps.
The Geothermal Hybrid System
A highly trained licensed geo drilling team drills, installs and seals the ground loop heat exchange mechanism for years of reliable operation, and charges the system
with a proprietary heat exchange medium which is 100% environmentally benign. This mechanism is protected by a proprietary conductive casing providing optimum performance during all seasons. Depth of the ground loop can vary from 40 to 100m deep according to heat transfer demand and local soil conductivity, density and aqueous saturation levels.
The Geoflo Hybrid22 energy exchange unit is thermally insulated and mounted adjacent an external wall and integrates the geothermal energy feed. This is controlled by an Australian designed AI (Artificial Intelligence) brain that is enclosed in the outdoor unit. This monitors operations and displays parameters for easy installation, commissioning and diagnostics. The AI design also includes Rinnai
noise mitigation technology providing whisper quiet operation (so your neighbours won’t complain about noisy fans at the fence line), and smooth adaptive start-up technology to protect sensitive components such as compressors.
There is abundant renewable energy capture in the Rinnai Geoflo Hybrid22 design. The energy that is surplus to the heating and cooling of your home is captured and diverted by Rinnai’s unique technology to provide free heating of your home’s hot water needs.
*When the Geoflo hybrid is in operation, surplus energy is supplied to your hot water storage tank delivering free hot water heating.
A variable speed supply air fan inside the home, is much like a traditional airconditioned system. It automatically adjusts air flow to provide optimum capacity and comfort at your choice of indoor set point temperatures. The indoor unit is electronically commutated to achieve greater efficiency and whisper quiet indoor operation.
With your home or office Wi-Fi connection, you can control your indoor thermostat from anywhere. Or with the Total Connect Comfort app, you can monitor or control your heating and cooling system using your smartphone or android from anywhere and at any time you choose. Back home, you’ll like the look of the Rinnai Geoflo Hybrid22 thermostat’s colourful, high-definition touch screen. All round, and all year round, the Rinnai Geoflo Hybrid22 system is a winner for your home comfort and the environment.
Traditional 22 kW climate systems must have 3 phase power supplied, costing thousands of dollars to the householder. The Geoflo Hybrid22 system generates 22 kW but magically only requires single phase power.
