Heat pumps are tremendously economical and sustainable climate control devices. In the warm months, they pull hot air out of your home or business and during the cold winter months, they pump in warm air. The idea of efficiently warming frigid air may leave you somewhat skeptical and asking the big question. How does a heat pump work in winter?
Making Warm Air
Think about a heat pump like a refrigerator. There’s all that nice cold air inside, but its fan is blowing hot air out of the back. You basically have hot and cold air being created from one unit. The heat pump gathers outdoor warm air and circulates it into your home or business. Believe it or not, there is always warm air to be found. Although our 98-degree bodies may feel only the bitter cold, there’s still warmth to be gathered. The only time it really becomes less efficient is when it goes into defrosting mode to clear away ice buildup. There are three basic types of heat pumps, air, water and geothermal.
• Air-Source Heat Pumps: These are generally comprised of two main parts. There’s a compressor outdoors that resembles a central air unit. Inside, there’s an air handler that resembles a gas furnace. The strength of this unit is based on the compressor. When buying an air-source heat pump, check on the reliability of the compressor.
• Water-Source Heat Pumps: This type gathers its heat from a body of water. Lakes, ponds, rivers or the ocean are common sources. By running water through a series of pipes below the surface, heat is gathered and transferred to your home or business.
• Geothermal: This type gathers warm air from underground. Once you get a few feet below the freeze, the ground tends to maintain a steady temperature. Although costlier to install, geothermal heat pumps are highly cost efficient in the long run.
Because heat pumps also have the reverse ability to cool during the warmer months, they may make more sense to install than traditional heating or cooling systems. And in terms of their heat source, nothing is more sustainable than warm natural air or water.
