HIU Salzburg HT, compact residential unit, hydraulic interface unit
for hot water production by the continuous flow principle and transfer
of heat to radiator heaters. Installation as flush mounted version with
flush box or as surface-mounted version with cover.
The pipe connection to the residential unit hydraulic interface unit
is created using a patented installation system with pre-installation
bracket. Option to connect the pre-installation bracket from the floor.
