<p>An instantaneous water heater, such as a shower heater, has an inlet (11) and an outlet (12), heating means (15) to heat the water as it flows from the inlet (11) to the outlet (12), a microprocessor control means (16) operable to adjust the level of heat dissipated to the flowing water by the heating means (15) and hence to change the temperature of the outflowing water, and one or more memories (M1 to M4) which are individually programmable by users of the heater to signal the control means (16) to cause the control means to adjust the level of heat dissipation to the flowing water to achieve a predetermined (preset) water temperature at the outlet (12) when a control (C1 to C4) is subsequently selected by a user. Thus each member of a family can programme one memory of the heater for the delivery of water at a predetermined temperature. <IMAGE></p> |
