    Am I right in saying it's not advised to connect a rad to the immersion heater?
    And if not why not?
    Is it because the water that passes through the rad will end up coming out of your tap and this is not advised for some reason?

    Yes and why would u anyway?
    Water in the cylinder is fresh water. Fresh water will rot steel. Radiators are made from steel.

    Cold water will come out of your hot tap as you've lost all the heat to the rad.

    What are you trying to achieve? Do you want to have a radiator in the bathroom but don't have a boiler?

    if you want to heat the room electrically, why not get an electric radiator?

    Hi, Thanks for your reply.
    Yes it's to put a radiator in the bathroom which is where the immersion heater is.
    There is a gas boiler in the house and central heating just no rad in the bathroom.
    A plumber came out to give a quote and he seemed to suggest linking a rad from the hot tank would be an option. But maybe he meant something else. Is the hot tank a separate closed system from the central heating then?
    I thought my hot tank got hot when the central heating came on.

    Your central heating heats a small volume water circuit that runs a pipe through the internal of your hot water cylinder and acts like a heating element in a kettle except that the element is simply full of hot water and not electrically powered. The central heating water is therefore seperate from the hot water that comes out the tap.
    The central heating circuit is the one to take a rad off.
    The immersion is another heating element dipped directly into you hot water storage and it is basically a large electrical element. This heats the main water volume that comes out of tap. You cannot run this water through a rad.
