Heat pumps can act as both furnace and air conditioner in moderate climates like ours here in the Portland area of Oregon. These versatile systems are known for ultra-efficient operation because they work by moving heat rather than burning fuel to create heat.
As needed, the heat pump uses just a bit of energy to cause a switch in the natural tendency of heat, which is to move from a warm location such as the ground or air to a cooler location like your house. Air-source pumps are the most commonly used, taking outdoor heat and running it through reversible refrigerant coils.
The efficiency of this type of system means you will save a significant amount of money on monthly utilities. Here’s an outline of the different types of air-source pumps that you might consider for you home:
Some larger air-source heat pump systems are contained in one unit holding all the refrigerant-filled coils, installed on the roof and connected to the home or building’s duct system.
Home systems, however, are typically split systems with inside and outside components connected through a wall. Inside, one or more indoor components distribute the heated or cooled air. No ducts are needed for this type of system.
Another air-source type is the absorption pump, running on natural gas, propane, solar energy or geothermal water sources. Absorption pumps can be useful for large homes. Unlike a standard air-source pump, which compresses the refrigerant, an absorption pump absorbs ammonia into water, and pressurizes it. The ammonia is then boiled out of the water, and the process repeats.
