Geoflo Hybrid 22

Environmentally responsible climate control down under

Harnessing the abundant free renewable energy right under your feet

Everyday 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 Hybrid ²² 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 Hybrid ²² technology diverts surplus energy to the generation of essentially free hot water for your home.

Watch the video below to learn how the Geoflo Hybrid ²² works.

Renewable clean energy
Geothermal energy is extremely affordable and can assist to cut electricity consumption by up to 50% 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.

Quiet Operation
The reduction in moving parts and high noise generating components in the Rinnai Geoflo Hybrid 22, delivers smooth quiet operation, devoid of the higher Db noise levels of older technologies. That keeps neigbours and families comfortable and renders the environment more peaceful.

Flexible design
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.

Very durable
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.
