Introduction
The Sanden 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.
We have also considered energy efficiency. By using CO
2
as the refrigerant we have produced
one of the most energy efficient units currently available. It’s even more efficient when
connected to off-peak power
1
and the noise level is so low it will operate unobtrusively
throughout the night.

operating conditions may vary depending on the type of off peak tariff that is available in
your area. The unit must have a minimum of 5 hours continuous power available at all time to
allow the unit to operate without affecting reliability.
