Filling section thermaliQ:FB2

Two powerful groups that make up an overall system

The filling section thermaliQ:FB2 is the complete unit for conveniently filling the heating system or for the make-up water feed of closed heating systems. After mounting the boiler and piping for the heating system, the thermaliQ filling section provides you with the basis for the initial filling with optimally treated fully demineralised water. Filling the heating system is more convenient than ever for you. As the filling section actually combines three elements that stand for the generation of perfect fully demineralised water: The filling group thermaliQ:SB13 and the treatment group thermaliQ:HB2 which already includes the filling cartridge desaliQ:HB2


In order to document the amount of water flowing through, we recommend installing an additional water meter (Order no.: 702 845).
