The invention provides a fitting-assembly for a central heating system which comprises substantially a heat source, a plurality of heater units, in particular radiators, and a system of supply and return conduits between the heat source and the heater units, characterised in that it comprises one or more first fitting-units that are incorporated into the system of supply and return conduits, each comprising a connection point to a supply conduit and a connection point to a return conduit of the supply and return conduit system between the heat source and the heater units, and one or more second fitting-units ("fitting-block") that each are functionally connected to a respective first fitting-unit and each enclose a housing in which is contained at least one supply chamber having a connection for a supply conduit from the first fitting-unit and a return chamber with at least one connection for a return conduit to the first fitting-unit, said supply chamber further comprising a connection for coupling to the inlet of a heater unit of the central heating system, and the return chamber further comprising a connection for coupling to the outlet of a heater unit of the central heating system. The invention also provides a separate second fitting-unit which is preferably directly fitted to the outlet of a heater unit, and preferably provided with a flow changeover device. |
