Introduction

The Sanden Eco Hot water Heat Pump System has been designed using the latest refrigeration technology to remove the heat from the air to heat water.

The refrigerant we use is CO2 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 the power requirement. By using CO2 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 power1 and the noise level is so low it will operate unobtrusively throughout the night.

 How it works

The Sanden Eco 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).

Note: 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.
