Introduction; How It Works - Sanden EcoPlus GAUS-300FQS Owner's Manual

Introduction

The EcoPlus Heat Pump Water Heater System has been designed using the
latest refrigeration technology to absorb heat from the outside air to heat water. The
refrigerant (CO ) has an extremely low global warning potential (GWP) so it allows us
2
to help keep a clean healthy earth for future generations.
We have also considered the power requirement. By using CO as the refrigerant we have
2
produced one of the most energy efficient units currently available. It's even more efficient
when connected to off-peak power* and the noise level is so low it will operate
unobtrusively throughout the night.

How it works

The EcoPlus Hot Water Heat Pump 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).

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 times to allow
the unit to operate without affecting reliability.
