3.3. Features of the Hydraulic System

Hydraulic systems of AKY boilers are similar. However, AKY050/070 boilers have some additional components if compared to

AKY032/034 models.

If more than one boiler is installed, you only need to sum their heat output values when the hydraulic circuit is shared

by multiple boilers.
