WatterSaver Heat-Pump Water Heater
To the best of our knowledge, this product is no longer available.
The idea of using a heat pump, instead of electric heating elements, to heat water is very compelling. “Heat-pump water heater technology gives you a quantum leap in efficiency, with energy savings around 55%,” says John Tomlinson of Oak Ridge National Laboratory (ORNL). “It is difficult to see energy savings of that magnitude in other appliances without a lot of work.” The challenge has been making this technology affordable and dependable enough to replace the simple electric-resistance water heater, which costs relatively little and has no moving parts.
