Ductless mini-split heat pumps can provide energy efficiency, cost savings, and temperature flexibility, Forbes reports.
Mini-split heat pumps have been used around the world for many years. But they have been gaining in popularity in the United States in recent years because of their energy efficiency, size, ease of installation and the ability to zone the different areas of the house. Ductless heating and cooling systems, also known as mini-splits and ductless heat pumps, were first introduced to the U.S. just about 35 years ago from Japan.
These systems are un-ducted so there is no leaking air from ducts. According to the United States Department of Energy, “Duct losses can account for more than 30% of energy consumption for space conditioning, especially if the ducts are in an unconditioned space such as an attic.”
During the colder months, heat pumps move heat from the cool outdoors into the warm house, and during the warmer months, heat pumps move heat from the cool house into the warm outdoors. They move heat rather than generate heat, so they can provide up to four times the amount of energy they consume.
