Ultra High Efficiency Reduces Energy Bills: Uses over 70% less electricity
The SANCO2 system uses an inverter-type compressor, DC fan motor and pump. Our design minimizes energy consumption, maximizes water-heating capacity, and allows for faster recovery, resulting in significantly lower operating costs than electric-resistance storage water heaters or conventional heat pump water heaters.
Minimal Impact on Global Warming: Unique Ozone-Friendly CO2 Refrigerant
Heat pump water heaters commonly use synthetic refrigerants, such as R410A or R134A. Although these refrigerants do not deplete the ozone layer, they can have a significant impact on global warming. The CO2 refrigerant uniquely used in the SANCO2 system has an extremely low Global Warming Potential*, and CO2, a natural refrigerant, does not deplete the ozone layer.
*Global Warming Potential (GWP) is a measure of how much a given mass of greenhouse gas is estimated to contribute to global warming. It is a relative scale which compares the gas in question to that of the same mass of carbon dioxide (whose GWP is equal to 1).
Low Profile Design
- Whisper-quiet noise level (38dB)
- Slimline heat pump design for a reduced footprint
- Greater first hour rating than all heat pump water heaters
- Faster recovery after hot water draw
- Two sizes to best fit your hot water needs
Extended Operating Range
- Hot water production down to -15°F
- 149°F delivered hot water temperature
- No need for a back up electric element in the storage tank
Easy Installation: FLEXIBLE 2-PIECE SYSTEM
The tank is installed indoors and the heat pump outdoors (up to 25 feet away) with only water piping connections required between the two.
This flexible SANCO2 design offers several advantages including maintaining comfortable indoor air temperatures (unlike conventional heat pump water heaters that ’scavenge’ heat from the indoor air), along with reducing in-home noise.
Efficient Operation: How the Sanden SanCO2 System Works
A heat pump uses a small amount of energy to move heat from one location to another. In the SANCO2 system heat in the air is absorbed by a natural refrigerant, CO2, which is ozone friendly and does not contribute to global warming.
The warm gaseous refrigerant is circulated in the system via a compressor. As it passes through the compressor, its pressure rises, as does its temperature. This hot refrigerant then passes through a heat exchanger to heat the water, which is then pumped to the storage tank.
