(54)	An improved method of insulating a hot water cylinder

(57) A method is disclosed of the manufacture of an insulated hot water container (11), the container (11) being within a housing (13). The method includes the steps of selecting a base portion (12) to support the container (11), locating the container on the base portion (12). A sealant (18) is provided in a well (17) between an outer rim wall (15) and a locating wall (16) of the base portion (12), and an outer casing (13) located in the well. The outer casing (13) rests on or is embedded in the sealant and surrounds the container (11). A top moulding is located on the open end of the outer casing to enclose the container (11). Liquid prepolymer is then admitted into the space between the outer casing and the container and the prepolymer polymerised.
