Thermodynamic water heaters use the principle of heat pumps. They use a renewable energy by drawing calories from the ambient air. They then reinject the captured calories to heat the water.

Ventilation plays an important role in this application. It allows the extraction of the necessary air and its calories.

The fan installed must meet several criteria:
- low noise level to avoid disruption of daily life
- high efficiency level to meet the ecological challenge of this application. Energy savings are achieved by using a constant airflow EC technology fan. The electronics integrated in the fan allow the fan speed to be reduced whenever possible, thus reducing its consumption.

Our TRE-GRE single inlet centrifugal fans with EC technology and our RRM modules fully meet these criteria.
