Bear in mind that only the water above the primary coil in the cylinder is heated. The bottom of the cylinder is usually cold, so a 120 litre cylinder may only hold 90 litres of hot water.
Both the recovery rate of the cylinder and the temperature of the cold feed are significant factors.
Drawing off hot water too fast may cause turbulence in the cylinder causing the incoming cold water to mix with the hot water in the cylinder, instead of the hot and cold water remaining stratified.
