Introduction
The Sanden SANCO ₂ Heat Pump Water Heater System has been designed using the
latest refrigeration technology to remove the heat from the air to heat water. The
refrigerant we use is CO
2
which does not contribute to global warming so it allows us to
help keep a clean healthy earth for future generations.
By using CO
2
as the refrigerant, we have produced one of the most energy efficient units
currently available. It is even more efficient when connected to demand response power
and the noise level is so low it will operate unobtrusively at any time.
How it works
The Sanden SANCO
₂
Heat Pump Water Heater System heats water by transferring the
heat from the surrounding air to the water using a refrigerant. The refrigerant is heated by
a heat exchanger that absorbs heat from the surrounding air (Figure 1).

Note:
The unit must have a minimum of 5 hours continuous power available at all time to allow
the unit to operate without affecting reliability.
