Energy Efficiency Technologies – Air Source Heat Pump vs. Ground Source Heat Pump
Journal of Sustainable Development, 2009 Heat pump deserves the name of eco-innovation. It uses ‘free energy’ - warmth collected in the soil or in the air to provide heat ing and cooling. There are two main types of heat pumps – air source heat pump and ground source heat pump. How do they work? What are the benefits of each system? How do they compare?
