    It is a normal central heating and hot water system.

    Not knowing anything about plumbing all I can tell you is that the hot water system works normally but the central heating vents into the header tank as soon as it is switch on

    By header tank, do you mean a tank up on or in the floor joists with one pipe going to the boiler? If so, it is perfectly normal for that tank to get warm when the boiler heats.
