ABSTRACT:
A hot water tank particularly for a beverage brewing apparatus of the infusion type in which the hot water tank has a water draw-off tap at a position between the top and bottom of the tank and a thermostat above the outlet in the tank to the tap and a control means connected to the thermostat such that water may only be drawn off through the tap when the temperature of water above the tap outlet is at least as high as a predetermined temperature. The controller ensures that the user cannot draw water from the tank until the temperature of the water reaches the predetermined temperature. A water supply to the tank bottom ensures that the tank is kept full of water and in the case of the brewing apparatus this ensures feeding of hot water to an infusion spray head. Preferably the tap is prevented from being enabled to draw off water while infusion is taking place due to the provision of a control valve in the connection between the tap and the water tank.
