NEW EcoHeater
DSEH200301.01.EN
Continuous product development may give rise to specification changes without notice.
3.2 Function
General
The incoming water to the EcoHeater must be at least 20 °C to ensure the
operational safety of the EcoHeater.
Recovered energy is returned to the property's heating system.
