The main benefit of using a copper or stainless header tank to feed your hot water cylinder or heating system is that, unlike the more common plastic tanks, they will not be susceptible to melting or warping due to prolonged overheated water. This can be a particular problem on a system which incorporates a solid fuel boiler or uncontrolled heat source, as they are capable of heating the water to in excess of 100°C.
