Midea recently announced the launch of a new highly efficient heat pump water heater that will soon be available in North America, PR Newswire reported.Midea’s new heat pump water heater can produce up to four kilowatts of heat for every kilowatt of power input, the company said. A traditional electric water heater produces up to one kilowatt of heat for every kilowatt of power input.

Heat pump water heaters use electricity to transfer heat from the surrounding air to water inside a storage tank. Because they work by transferring heat around instead of generating new heat, they are much more efficient than traditional heating methods
