electric consumption by pre-heating the
incoming cold water using the steam from

unit. The steam condenses on the cold fins
and the heat is transferred to the cold
incoming water. The water temperature is
increased from ~ 10 °C to ~ 50 °C, that
means an initial energy saving by heating
up the incoming water of ~ 40 °C.
