How Do Heat Pumps Work?

While most heating systems burn fuel, a heat pump moves existing heat from one place to another. In the case of an air-source heat pump, heat is collected from the exterior air, concentrated via an outdoor compressor, and distributed inside through an indoor room unit. Heat pumps require electricity to run, but can deliver more energy than they use. In summer, a heat pump’s operation is reversed to air condition your home by moving heat from indoors to out.

  • Effectively heat and cool with a heat pump system
  • Zone friendly: heat only the rooms you need to

Air-Source Heat Pumps

Also called mini-splits, cold-climate and ductless heat pumps consume far less energy than electric resistance, propane, or oil heating systems. Typically, one heat pump per room or a multi-zone set-up is necessary for whole-home heating. While effective in cold weather, an air-source heat pump often requires supplemental heat on subzero days. Find out if a heat pump is right for your home or business.

  • Lower energy bills by switching from electric resistance, propane, and oil to heat pumps
  • No combustion means no carbon monoxide
  • No fuel storage or risk of running out of fuel

Ground-Source Heat Pumps

These high-efficiency systems can provide 100% of a building’s heating and cooling needs. They work by extracting stored heat in the ground or groundwater and circulating it through a building. Due to excavation costs, ground-source heat pumps come with a much higher price tag than air-source heat pumps. Contact us to find out if this technology is suitable for your building.

  • One system to heat, cool, and supply hot water for your home or business
  • Sustainable energy source, delivers more energy than it uses
  • More consistent, steady output and performance than air-source heat pumps

Commercial Water-Source Systems

The most common system combines a cooling tower, boiler, and water source heat pumps. Hybrid roof-top units are another exciting option that combines a heat pump and fossil fuel system, automatically switching between the two for optimal efficiency and performance. A third option is the commercial Variable Refrigerant Flow (VRF), which is a giant multi-split system that can heat and cool simultaneously. As with mini-splits, VRFs may require a separate back-up system during subzero days.
