ABLUTIONARY INSTALLATIONS

摘要

A shower system in which the cold water supply (3) to a thermostatic electric shower (1) is pre-heated by heat exchange with wastewater from the shower (1) in a heat recovery unit (21) connected to an outlet of a shower tray (17) for collecting and draining wastewater discharged from a shower head (9). The shower (1) is thermostatically controlled and responds automatically to compensate for the pre-heating of the cold water supply to maintain substantially constant a selected water temperature such that pre-heating the cold water supply does not cause the temperature of the outlet water discharged by the shower (1) to increase during operation of the shower (1).
