What Is A Heat Pump And How Does It Work?
Heat pumps are versatile climate systems that transfer heat rather than generate it. In winter, they capture heat from the outside air or ground and move it indoors. In summer, the process reverses, removing heat from your home to cool the space. This dual functionality makes heat pumps a unique and adaptable solution for a variety of climates across the U.S.
There are several types of heat pumps:
- Air-source heat pumps (most common, using outside air)
- Ground-source (geothermal) heat pumps (using thermal energy below the surface)
- Water-source heat pumps (drawing thermal energy from water sources)
Each type is designed to optimize efficiency and comfort depending on regional resources and needs.
Key Advantages Of Heat Pumps For American Homes
