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.

Comfortable, Quiet, Consistent

Inverter technology allows your system to use only as much energy as it needs. A variable speed system maintains consistent comfort levels, regardless of outdoor conditions, by using the proper amount of energy needed. By fluctuating operating speeds rather than running at a constant speed, the Ecoer system saves energy by maximizing lower speed operation while maintaining consistent temperature inside your home.
