One of the most efficient and safe ways to keep your home comfortable year-round in the Chicago area is with heat pump. Three viable heat pump options exist for conditioning your home: air-source, geothermal and absorption. All heat pumps operate on the same principle of moving heat from one place to another rather than creating it using fuel. Heat pumps have reversing valves that change the flow of refrigerant to accomplish the conditioning process.
Air-Source Heat Pumps
These are the most common types of heat pumps. They condition by using refrigerant and the air to extract heat in the winter and discharge it in the summer into the air. If you're considering an air-source system for your home in our region, choose one with a high heating seasonal performance factor (HSPF). The minimum starts at 7.7 and goes as high as 10.
This system starts to lose efficiency around 30 degrees. One with a higher HSPF, especially if it has a scroll compressor, will provide heat in lower temperatures. Such a compressor can deliver up to 15 degrees warmer air than one with a piston compressor.
Of the heat pump options, this will deliver dependable heat during the winter, regardless of outdoor temperatures. It extracts heat from an underground loop field and deposits the wasted heat from your home in the summer back into the ground. This type of heat pump costs more to install, but federal energy tax credits are available through the end of December 2016 to offset its cost. It has the longest system life of any other kind of heat pump.
These systems use ammonia for the heat transfer process and rely on electricity, gas, propane or even solar as an energy source. They're used more in commercial settings than residential, but recent technological advances make them available for larger homes.
