The Sanden SANCO2™ Heat Pump Water Heater is a two-part system consisting of a tank (usually placed indoors) and a heat pump unit (usually placed outdoors, up to 50 ft away from the tank). The heat pump works like a reverse air-conditioner, drawing heat energy from the atmosphere and applying it to water in the tank. This technology is already in wide use in industrial applications as well as residential water heaters in countries like Japan and Australia.
The Sanden SANCO2™ works just like a conventional heat pump, except that it uses CO2 as a refrigerant. Due to the unique properties of CO2, the Sanden operates very efficiently in a wide range of temperatures. It is able to extract heat from the air all the way to -20°F and beyond It accomplishes this in a single heating stage, raising the water temp as high as 175°F at .3 gallons/minute. The result is a system that requires radically less electricity to heat water when compared to conventional hot water systems and works without a backup coil in a very wide range of climates.
While the Sanden system is a perfect choice to replace an existing gas or electric hot water tank in any residential or multifamily application, the ability to work at low exterior temperatures and still supply hot water at 175°F means the same system can be the total heat demand solution for today's new low energy homes.
