Expansion vessel
It is important when installing the expansion vessel to position it at the
highest point in the circuit, preferably above the heat pump. If there is a
low ceiling making it impossible to fit the tank above the pump, it can be
positioned as illustrated in the figure to the left. It is important to install
the tank so that any air disappears upwards. If the tank is installed
incorrectly, the air will continue on in the circuit (
Æ
Figure 17).
Fig. 17 Installing the expansion vessel
As an alternative to a plastic vessel a membrane expansion vessel in the
heat transfer circuit can be used.

Antifreeze/Corrosion preventative
