In 2023, Americans purchased 21% more heat pumps than natural gas furnaces¹. So, what are heat pumps, and why are businesses and homeowners alike choosing them for temperature control?
Heat pumps are systems that extract heat from one place and transfer it to another. The system includes a closed loop filled with refrigerant that is exposed to air, earth, or water, and connects to the heat pump unit, which has a compressor, evaporator, and condenser. The refrigerant absorbs heat where it is higher and releases it where temperatures are cooler, resulting in consistent, comfortable temperatures inside.
Heat pumps are better for the environment because they do not burn fossil fuels and use a small amount of electricity, reducing a business’s carbon footprint. Ground source heat pumps are three times more energy efficient than gas furnaces, and air-source heat pumps improve energy efficiency by 50%.²’³
Heat pumps offer many other advantages. They are multipurpose, generating both heating and cooling. They are long-lasting, with a lifespan of up to 20-plus years, and are typically more reliable, requiring less repair and maintenance than gas furnaces and air conditioners, saving the business even more money over the lifespan of the unit.
Features and advantages of different heat pump types:²'³
All heat pumps have some external source where they draw or distribute heat. The three primary types are:
- Air-source heat pumps: The most common type of heat pump, the air-source heat pump, transfers heat from the outdoor air to indoors. These are often the most affordable and easiest to install, but extreme wintry weather conditions impact their performance.
- Water-source heat pumps: These extract heat from water sources like wells, lakes, or ponds. They require an independent water loop system. More efficient than air-source, they require a suitable water source.
- Ground-source/geothermal: Ground-source (geothermal) heat pumps transfer heat from the ground. The most efficient and reliable type of heat pump, ground-source pumps generate consistent cooling or heating, regardless of the outside temperature. They also have a higher upfront installation cost.
Deciding if a heat pump is right for your business:
Business and building owners will need to evaluate and balance several factors to determine if a heat pump is right for them, and if so, which type.
