Hot-water tank
If the heat pump will be used for heating hot water, you
must integrate special hot-water tanks in the heat pump
system. The storage volume must be sufficient so that
the required hot water quantity is available even during
a power outage.
NOTICE
The heat exchanger surface of the hot water
tank must be dimensioned so that the heating
capacity of the heat pump is transferred with
minimal spreading.
We offer a variety of hot-water tanks for you to choose
from. They are optimized for use with your heat pump.
NOTICE
Integrate the hot-water tank in the heat pump
system corresponding to the hydraulic diagram
for your system.
