"It looks a little like a sleek window AC, but a new device from Chinese appliance giant Midea is actually a reversible heat pump that can both cool and heat a home-and it's designed to heat efficiently even when the temperature outside drops as low as 22 degrees below zero. The heat pump, called the Midea PWHP, just launched commercially after years of development. Over the last few weeks, I've been testing it in freezing temperatures in upstate New York."
"Like other heat pumps, the PWHP transfers warmth from the outdoor air to heat your space, using relatively little energy. But the new heat pump is designed to be much easier to install than other versions, which reduces the overall cost and complexity of switching. The inspiration for the idea originally came from New York City, where the state and local government launched the Clean Heat for All Challenge in 2022-which offered the potential of a contract with the city's public housing authority,"
The Midea PWHP is a reversible heat pump with a window-AC-like form factor that both cools and heats a home and operates efficiently down to 22 degrees below zero. Commercial launch followed years of development. Tests in freezing upstate New York showed it outperformed a gas furnace while using less energy. The unit transfers warmth from outdoor air using relatively little energy and is engineered for much easier installation than typical mini-splits or central units, reducing cost and complexity of switching. The design concept originated from New York City's Clean Heat for All Challenge and development work began in Midea's Louisville office.
