27 giugno 2007 - Conventional thermally powered water heaters are 80 to 95% efficient. The new thermally powered heat pump (TPHP) reported herein is over 140% efficient. In addition, the cold end of this TPHP produces useful
chilling.
The amount of energy-free chilling is equal to the amount of heat pumping. The combination of the worlds highest hot water heating efficiency, plus energy-free chilling, all from a single economic appliance, makes this a very significant development.
