A heat exchange unit for installing above a shower tray 'ST' comprising a housing having an upper surface 21 upon which a person stands, a conduit divided into two or more parallel conduits 13a - 13e communicating mains water connected between a mains water supply and the water inlet of a shower unit and the conduits 13a - 13e being located in at least one channel 4a - 4e communicating waste water. The housing of the unit has a bottom surface positioned on one or more load bearing supports 129, which may be installed using a levelling tray (120, fig 21) to produce strips or pockets of cement bedding compound, putty or catalysed resin that space the unit from the shower tray to permit the wastewater to flow to a drain. Once the load bearing supports have set hard the levelling tray (120) may be removed. Alternatively the unit may be installed without the aid of a levelling tray (figs 24 and 25). The upper surface 21 may be supported on vertical ribs 9 which may be integral with the housing. Adjustable spacer bars (50, fig 10 and 124, fig 21) may be located around the edge of the housing and levelling tray (120). The housing may be supported on height adjustable legs. A cleaning device (80, figs 16 - 18) for the conduits 13a - 13e may be provided. |
