Fitting-assembly and fitting-block for a central heating system

Abstract

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.

1 . A fitting-assembly for a central heating system which comprises a h at source, a plurality of heater units such as radiators, and a system of supply and return conduits between the heat source and the heater units, characterised by (a) at least one fitting-unit 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 (b) at least one fitting-block that is functionally connected to a respective said fitting-unit and each includes a housing in which is contained at least one supply chamber having a connection for a supply conduit from the fitting-unit and a return chamber with at least one connection for a return conduit to the said fitting-unit, said supply chamber further communicating with a connection for coupling to the inlet of a heater unit of the central heating system, and the return chamber further communicating with a connection for coupling to the outlet of a heater unit of the central heating system.  
     
     
         2 . A fitting-block for a central heating system comprising a housing defining a supply chamber having at least one connection for a supply conduit from the central heating system and a return chamber defining at least one connection for a return conduit to the central heating system, 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.  
     
     
         3 . The fitting-block as defined in  claim 1  or  2 , characterised in that said fitting-block is directly connected to the inlet and/or outlet of a heater unit of the central heating system.  
     
     
         4 . The fitting-block of  claim 3 , characterised in that said fitting-block is directly fitted to the outlet of said heater unit.  
     
     
         5 . The fitting-block of  claim 3  or  4 , characterised in that said fitting-block is fitt d crosswise to the heater unit.  
     
     
         6 . The fitting-block of any one of the claims, characterised by further comprising a flow changeover device enabling the reversal of the flow direction within said block, control of the flow rate and a complete cut-off of the flow.  
     
     
         7 . The fitting-block of any one of the preceding claims, characterised by further comprising one or more measuring and/or control means for controlling one or more physical parameters in said block.  
     
     
         8 . The fitting-block of any one of the preceding claims, characterised in that one or more supply and return conduits are connected to said block by push-in fittings or compression fittings.  
     
     
         9 . The fitting-block of any one of the preceding claims, characterised in that said fitting-block is surrounded by an enclosure having one or more recesses for connecting pipes.  
     
     
         10 . The fitting-unit as claimed in  claim 1 , characterised in that said connecting points are arranged such that connections to and from the at least one fitting-unit and to and from the at least one fitting block are made by push-in fittings or compression fittings.  
     
     
         11 . The fitting-unit as claimed in  claim 1  or  10 , characterised by a cover plate optionally having one or more recesses for connecting pipelines with said fitting-block.  
     
     
         12 . A fitting-assembly for a central heating system, constructed and arranged substantially as hereinbefore described with reference to and as illustrated in the accompanying drawings.  
     
     
         13 . A fitting-unit for a central heating system, constructed and arranged substantially as hereinbefore described with reference to and as illustrated in FIGS. 5 and 6 of the accompanying drawings.  
     
     
         14 . A fitting-block for a central heating system, constructed and arranged substantially as hereinbefore described with reference to and as illustrated in FIGS.  1  to  4  of the accompanying drawings
