The Benefits of Geothermal Ground-Source Heat Pumps
What Is Geothermal Heating?

Geothermal heating, powered by ground-source heat pumps, uses the earth’s natural energy to heat and cool a home, either from the earth or from a body of water.
Climaveneta by DeLonghi manufacture these extremely efficient and environmentally friendly systems. They have a high initial capital cost but can produce very low running costs. In fact geothermal heat pumps are the most efficient way to heat a whole home; the systems work on a rate of at least 4:1 (for one unit of electricity you will get four units of energy), and up to 5.5:1, no matter what the ambient air temperature is. As such, these systems particularly suit a colder environment.
How Do Ground-Source Heat Pumps Work?
No matter where you are in the world, a few metres below the earth’s surface the temperature remains relatively constant, despite the temperature outside. Ground temperature is often warmer than the air above it during the winter and cooler than the air in the summer. Ground-source heat pumps harness this energy store by exchanging heat with the earth through a ground heat exchanger, moving heat from the ground to a dwelling in winter, and pulling heat from the dwelling and expelling it into the ground during summer.
Instead of creating heat by burning a fuel, ground-source heat pumps move heat from one place to where it is needed. Electricity consumption is reduced and the natural, renewable energy from the earth is used instead of fuels like diesel or gas. The systems can be installed nearly anywhere with enough space for the ground collector and all the pipes are buried under the ground, allowing for more flexible exterior designs which don’t have to account for HVAC equipment.
In order to retain efficiency (and low running costs) and to keep the system running smoothly, we recommend biennial servicing for geothermal heat pumps.
