Observe the angle of the collectors

For a system for domestic water heating, we recommend the absorber

align 45° to the sun. With the combination of service water heating & heating

we recommend aligning the absorber at 60° to the sun.

Observe the operating pressure

The operating pressure (min. operating pressure) of the system P should be set in the cold

state (20°C) so that a pressure of 1.5 bar results at the level of the collectors (headers).

Example:

The collector was installed at a height of 10 m above the membrane expansion vessel

(MAG). expansion vessel (MAG). P = (h x 0.1) + 1.5 bar, P = (10 x 0.1) + 1.5 bar corresponds to

P = 2.5 bar. The inlet pressure of the MAG should be set 0.3 - 0.5 below the system pressure

P in the depressurized state.

This is only a rough guide. Please use the easy system planner for the design, which you

can download at www.akotec.eu.
