The coil circuit built into the hot water tank is connected to the heating circuit. Therefore, filling this circuit is
simultaneous with the heating circuit. To do this, open the automatic air vent located at the entrance of the
coil at the top of the tank (see
Figure 6.1 ) during the heating circuit load to ensure complete removal of air.

Figure 6.1. Filling the DHW coil circuit
In ecoGEO C1 and C2 models, draining the tank coil circuit is done together with the heating circuit using the
drain valve located under the heating pump (see section 3.4).
To empty the tank coil circuit in ecoGEO C3 models, use valve directly below the DHW circulation pump (see
section 3.4).
NOTE
Do not add anti-corrosion additives or antifreeze to hot water tank coil circuit. It could damage the
seals or other components and cause leaking.
