Types of Heat Pumps

While our main focus in this article is to explore the value of air source heat pumps, it's crucial to understand the broader context of heat pump technology. Let's take a moment to look at the two primary types of heat pumps available in the market:

• Air Source Heat Pumps: These systems extract heat from the outside air, even in cold temperatures, and transfer it into your home. They can be used for both heating in winter and cooling in summer which makes them a versatile option for year-round climate control.

• Ground Source Heat Pumps: Also known as geothermal heat pumps, these systems harness heat from the ground. They use a network of underground pipes filled with a water and antifreeze mixture to absorb heat from the earth which maintains a relatively constant temperature throughout the year. While typically more expensive to install, they can be more efficient than air source heat pumps, especially in extremely cold climates.
