1. A liquid heating assembly, comprising:
- a heat-conductive element; and
a liquid heating enclosure comprisinga rigid section including a heat exchanger, anda relatively resilient and flexible section,wherein said heat-conductive element defines a displaceable, resilient, flexible diaphragm between said rigid section and said relatively resilient and flexible section and allows for expansion of liquid inside said rigid section, caused by freezing of said liquid, into said relatively resilient and flexible section,wherein said heat exchanger is for directly heating liquid in said rigid section and for indirectly heating liquid in said relatively resilient and flexible section via said heat-conductive element, andwherein at least said liquid heating enclosure defines a primary liquid flow pathway in said rigid section and a secondary liquid flow pathway in said relatively resilient and flexible section, said secondary liquid flow pathway supplying liquid to said primary liquid flow pathway via at least one aperture in said heat-conductive element.

6. A liquid heating assembly, comprising:
-
a heat-conductive element; and a liquid heating enclosure comprising a rigid section comprising a heat exchanger and a respective liquid conduit, and a relatively resilient and flexible section comprising a respective liquid conduit, wherein said heat-conductive element defines a wall between said rigid section and said relatively resilient and flexible section, wherein said heat exchanger is for directly heating liquid in said rigid section and for indirectly heating liquid in said relatively resilient and flexible section via said heat-conductive element, wherein said rigid section liquid conduit comprises a plurality of bifurcated conduit portions adapted to enhance the heat exchange between the walls defining the bifurcated conduit portions, heated by the heat exchanger, and liquid flowing therethrough, the plurality of bifurcated portions comprising straight bifurcated portions and curved bifurcated portions, and wherein at least said liquid heating enclosure defines a primary liquid flow pathway in said rigid section and a secondary liquid flow pathway in said relatively resilient and flexible section, said secondary liquid flow pathway supplying liquid to said primary liquid flow pathway via at least one aperture in said heat-conductive element. - View Dependent Claims (7, 8)
