For ponds with moderate heating and cooling demands, heat pumps give an energy-efficient solution to furnaces and air conditioners. Like your fridge, heat pumps use electricity to move heat from a cool area to a space that is warm, which makes the cool area cooler as well as the warm area warmer. During the heating season, heat pumps move heat from the cool outside into your hot home and throughout the cooling season, heat pumps move heat from the trendy home into the warm outside. Because they move heat instead of generate heat, heat pumps can provide equal space conditioning at as little as one quarter of the cost of operating conventional heating or heating appliances.
There are three types of heat pumps: air-to-air, water supply, and geothermal.
The most common type of heat pump is that the air-source heat pump, which transfers heat between your home and the outside air. High-efficiency heat pumps also dehumidify better than standard central air conditioners, leading to less energy usage and much more cooling comfort in summertime. Air-source heat pumps are used for several years in nearly all regions of america, but until recently they have never been used in regions that experienced prolonged periods of subfreezing temperatures. Nevertheless, in recent decades, air-source heat pump technology has progressed so that it now provides a valid space heating option in colder areas.
For homes without ducts, air-source heat pumps are also offered in a ductless version known as a mini-split heat pump. Moreover, a special sort of air-source heat pump known as a “reverse cycle chiller” creates cold and hot water as opposed to air, enabling it to be used with radiant floor heating systems in heating mode.
