Example of temperature boost at 3.5 kW:
Flow rate quantity
Increasing the temperature
Water temperature at the product's cold water connection
Maximum water temperature at the product's domestic hot water
connection
A temperature of 50 °C can be achieved with the lowest possible flow rate quantity and
the following inlet temperatures:
– VED H3/3 > 18 °C
– VED H4/3 > 21 °C
– VED H6/3 > 22 °C
