The previous answer is correct,the copper tank has a hot pipe in,inside is a heating spiral tube which transmits the heat to the water inside (there must be water in that copper tank!)This is your hot water to taps , so make sure water is going in & getting out of that tank.

Your copper cylinder is filled by a header tank (cold water) that will be in the loft space. If this tank is empty due to a faulty filling valve you'll get no hot water from the taps. Also make sure that all valves are in the open position.
