5.7 Storage Tank Elements
Coil for external source of energy
The coil integrated in the storage tank in some of the models, can be used to combine the heat pump with solar or
with an existent installation with solar or boiler. In case the coil will not be used, do not remove the plugs from the
coil inlet and outlet apertures, this will avoid thermal losses due to the contact of the air in the coil with the
surrounding hot water in the tank.
The available pocket for external sensor installation is prepared to have installed the available fixation systems of
sensors in TT to ensure correct contact with tank.
