Highlands GeoExchange, Geothermal Energy, how it works

Unlimited and renewable geothermal energy is stored in your backyard. By using state-of-the-art technology, we can harness this energy to heat and cool your home, creating a geothermal home heating and cooling system. This is called ground source heating and cooling using a water to water heat pump. In Winter, the heat pump extracts the heat from the ground and moves it throughout the home. In Summer, the heat from the home is expelled back into the ground. It’s all based on a hydronic heating and cooling system.


superior comfort

One of the most valuable features of a geothermal system is the luxurious level of comfort achieved.


Geothermal systems are the most environmentally-friendly heating and cooling solutions in the world.

energy savings

A geothermal system uses up to four times less energy than a conventional system to heat or cool the same area of a home.

quiet operation

The heat pumps and insulation we use keep noise levels to a minimum.

low maintenance

Our heat pumps last longer as they have fewer mechanical components and are easier to service.

safe and reliable

No flame, no flue, no odours and no danger of fire or carbon monoxide poisoning.

Highlands GeoExchange is the exclusive distributor of Ecoforest heat pumps in Australia and New Zealand. Ecoforest produce some of the most advanced and energy efficient ground source heating and cooling in the world. They’re simple to install, compact and economical.

A geothermal heat pump, also known as a ground source heat pump (water to water), operates based on thermodynamics to provide both heating and cooling for a house. It efficiently extracts heat from the ground or water through geothermal boreholes or trenches and transfers it into the building for heating. Conversely, during cooling, it extracts heat from the house and transfers it back to the geothermal loop field.

Among the geothermal heat pump types, water-to-water heat pumps are considered the most efficient. They work by transferring energy from one source to another. 

The exceptional performance of geothermal heat pumps allows us to greatly amplify the thermal energy produced compared to the electricity consumed. Depending on external conditions and the installation, these systems can generate 4 to 5 kilowatts of thermal energy for every 1 kilowatt of electricity consumed. This remarkable efficiency makes geothermal heat pumps a sustainable and cost-effective heating and cooling solution.

Highlands GeoExchange offers a number of heating and cooling solutions, including geothermal, aerothermal or a hybrid combination. All our systems use water-based hydronics to distribute the energy. Ultimately, we aim to harness alternative energy to power your home so you can enjoy the benefits of modern living without being reliant on the old power grid and create a scenario where the go-to is geothermal home heating and cooling.

This is a more cost effective and environmentally sustainable method than conventional gas or refrigerant-based systems. To learn more about our choices and systems we have in place, click here.
