HIU Salzburg NTwith radiator outlet, compact residential unit,
hydraulic interface unit for hot water production by the continuous
flow principle and transfer of heat to low-temperature heating and
radiator outlet. 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.
