Sanden SANCO2 Heat Pump Water Heater

Did you know that the water heater is the second largest use of energy after heating or cooling your home?

As a highly energy-efficient alternative to the traditional electric or gas water heater, our unique system saves money, reduces greenhouse gas emissions and eliminates the production of carbon monoxide.

Sanden CO2 Heat Pump Water Heater

The SANCO2 heat pump water heater system consists of two parts. The Outdoor Unit, where the hot water is produced, using the CO2 refrigerant to extract heat from the ambient air, and the 43- or 83-gallon Storage Tank, which is usually installed inside the home.

Installation of the unit is simple with two water pipes connecting the tank to the outdoor heat pump.

SANCO2. Hot Water, Naturally

 

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).

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.
