Part 1: Evaluation of Mini-Split Heat Pumps as Supplemental and Full System Retrofits in a Hot-Humid Climate
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....
Higher quality electronic line voltage thermostats (ELVTs) have been available for several years. Most models indicate temperature in degrees, and they're touted as energy savers. But how well do they work? [continue reading]
