An electric shower assembly comprises a shower head (figure 3, 55) for creating a spray of water and a pump 41 for pumping water from a water tank (figure 1, 29) to the shower head. A first electric heater 31 is adapted to heat water in the water tank to a predetermined temperature, while a second electric heater is adapted to heat water in the flowpath between the pump and the shower head to a temperature 10 above the predetermined temperature. Control means (figure 3, 57) is provided to energise either the first 31 or the second electric heater such that only one of the first and second electric heaters is energised at any time. The first electric heater 31 may be an immersion heater. The second electric heater can be incorporated into the control means (figure 3, 57) and may comprise an instantaneous water heater. A heat exchanger (figure 1, 21) and a digital thermostat 47 may also be included. |
