How Geothermal Works?







Features and Performance

Renewable clean energy
Geothermal energy is extremely affordable and can cut electricity consumption by up to 50% in comparison to a traditional ducted reverse cycle air conditioning system. Geothermal system heating and cooling performance are maintained during extreme climate conditions eliminating high seasonal energy costs.
Very quiet
When looking for a heating and cooling system that is virtually noise-free, look no further than geothermal. Being very smooth and quiet in operation, geothermal systems rely on the temperature of the ground to heat and cool your home.
Flexible design
Geothermal heat pump systems are designed with the user in mind. Geothermal systems can be installed in either new or retrofit applications. Since the hardware requires a lot less space than traditional HVAC systems, you can instantly save yourself some storage space 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.
