Removable Boiler

Abstract

A boiler assembly comprising a removable boiler unit ( 2 ) detachably connectable to a manifold unit ( 3 ), the arrangement being such that the manifold unit provides the boiler unit, in use, with a connection interface ( 7 ) to a pipework system, wherein boiler unit comprises a rear boiler unit section and a base boiler unit section ( 6 ), and there is provided a support structure ( 40 ) which extends from said base section to said rear section.

1 . A boiler assembly comprising a removable boiler unit detachably connectable to a manifold unit, the arrangement being such that the manifold unit provides the boiler unit, in use, with a connection interface to a pipework system, wherein boiler unit comprises a rear boiler unit section and a base boiler unit section, and there is provided a support structure which extends from said base section to said rear section. 
     
     
         2 . An assembly as claimed in  claim 1  in which the support structure comprises a strut. 
     
     
         3 . An assembly as claimed in  claim 2  in which the strut is arranged at an incline. 
     
     
         4 . An assembly as claimed in  claim 3  in which two such struts are provided, spaced apart, one at each side region of the assembly. 
     
     
         5 . An assembly as claimed in  claim 1  in which the support structure is arranged to provide support to the rear section. 
     
     
         6 . An assembly as claimed in  claim 1  in which the rear boiler unit section comprises a back plate or back panel. 
     
     
         7 . An assembly as claimed in  claim 1  in which the manifold unit comprises multiple fluid connection interfaces to allow detachable connection to the removable boiler. 
     
     
         8 . A boiler assembly comprising a removable boiler unit detachably connectable to a manifold unit, the arrangement being such that the manifold unit provides the boiler unit, in use, with a connection interface to a pipework system, wherein the manifold unit comprises a rear section and a base section, and a side of the base section arranged to allow the pipework system to pass therethrough. Put in other terms, this could be viewed as the pipe system having its point or area of entry to the boiler unit at the side of the manifold unit. 
     
     
         9 . An assembly as claimed in  claim 8  in which the manifold unit is such that the pipework system extends through a sidewall of the base section. 
     
     
         10 . An assembly as claimed in  claim 8  in which the pipework system comprises multiple pipes or conduits which are arranged to carry liquid to and from the manifold unit. 
     
     
         11 . An assembly as claimed in  claim 9  in which a side wall of the manifold unit is provided with multiple apertures to allow conduits of the pipe system to pass therethrough. 
     
     
         12 . A removable boiler assembly comprising a removable boiler unit detachably connected to a manifold unit, the arrangement being such that the manifold unit provides the boiler unit, in use, with a connection interface to a pipework system, wherein the manifold unit comprises a rear section and a base section, and the base section comprises multiple feet, which are arranged to engage with a floor or basal surface to support the manifold unit. 
     
     
         13 . An assembly as claimed in  claim 12  in which in which the feet are adjustable in that the support height of some or all of the feet can be adjusted. 
     
     
         14 . A boiler assembly comprising a removable boiler unit detachably connectable to a manifold unit, the arrangement being such that the manifold unit provides the boiler unit, in use, with a connection interface to a pipework system, and wherein a rearward section of the boiler unit comprises a combustion gas outlet and a combustion air inlet, and wherein internally of the boiler unit there is provided a conduit which connects from the combustion air inlet to a combustion assembly inlet and a conduit which connects from the combustion air outlet to a combustion assembly outlet, and wherein both conduits are substantially sealed from the internal space of boiler unit. 
     
     
         15 . An assembly as claimed in  claim 14  in which each of the conduits comprises a duct or ducting. 
     
     
         16 . (canceled) 
     
     
         17 . An assembly as claimed in  claim 14  in which the manifold unit comprises: a cold water inlet; a hot water outlet; central heating water return; a central heating water outlet. 
     
     
         18 . An assembly as claimed in  claim 14  in which the boiler assembly is arranged to receive a pre-heater assembly, which is arranged to pre-heat water by way of heat from the combustion gas prior to the water being heated by the gas combustion. 
     
     
         19 . An assembly as claimed in  claim 18  in which the pre-heater comprises a heat exchanger which allows heat exchange between outgoing combustion gas and water to be heated. 
     
     
         20 . An assembly as claimed in  claim 14  in which a flue box is provided at an upper, or uppermost, part of the removable boiler assembly. 
     
     
         21 . An assembly as claimed in  claim 20  in which the flue box comprises internal passageways to divert and separate incoming air from outgoing combustion gas. 
     
     
         22 . An assembly as claimed in  claim 14  in which the boiler assembly comprises a connection interface, which comprises multiple liquid conduits, and said interface comprises a respective plurality of connections between the manifold unit and the boiler unit. 
     
     
         23 . An assembly as claimed in  claim 14  in which the connection interface is provided at a front or forward section of the removable boiler assembly.
