More stringent energy efficiency standards and the demand for higher efficiency are increasing the popularity of technologies such as mini-split heat pumps (MSHPs). The market for ductless heat pumps is growing 10–30% annually. The U.S. mini-split market has seen a 221% growth rate over the last seven years, and a 20% growth rate is expected to continue, thanks partly to the introduction of the highly efficient, inverter-driven compressor. Growth projections are supported by high customer satisfaction, but most of the research has been conducted on space-heating applications.
