Geothermal Hydronic Heat Pumps

Geothermal heat pumps offer a great solution for powering your hydronic heating or cooling system for your home. With pipes laid underground, they generate energy from the relatively constant temperature of the  earth and use this to heat or cool the water in your hydronic system.

Geothermal heating and cooling systems tap into the abundant levels of energy stored below the earth’s surface to reduce your heating and cooling costs by as much as 30 percent. Even when it is freezing outside, temperature levels remain steady deep below the ground. With consistent temperatures under ground, geothermal heat pumps generate from one part electricity up to five parts heat. Best of all, geothermal systems can be installed in any sized home or business in virtually any location and are becoming increasingly popular in Australia.

In winter heat is extracted from the ground no matter what the ambient temperature. This is then converted into a higher temperature through a refrigeration system, similar to a standard air conditioner, except the heat is transferred to the water. This hot water can then be used for underfloor heating, radiators, trenches, etc. 

In summer, the heat from the property is absorbed into water through an air conditioning unit.  The warm water extracted is then passed through the cooler earth and cool water is then pushed back into the home and your hydronic cooling system.

Benefits of Geothermal Heat Pumps

  • Provide consistent heating or cooling through heatwaves or freezing conditions.
  • Low environmental impact, with limited carbon emissions
  • They consume 20-50% less energy than conventional heating or cooling systems
  • Can be used for heating and cooling your home
