Sorry,  my first post was misleading because the lighting and power circuits are on the full power rate all the time.
All the same if your washing machine draws hot water off at a time when the immersion heater has just switched on it will cool down all the water. Similarly if you run a bath at 10.05 in the evening the water can cool off rapidly as the immersion heater stirs up the storage tank.
