Questions about zoned heating

    Hi folks,

    We have a Potterton Promax HE3200 with a EPH T17 timer. Currently, we have no heating zones and no ability to heat water only. All of the rads have TRVs installed (with the exception of 1 x heated towel).

    The pipework in the house is not what I'd call "integrated". The house was built in 2001. I've no idea how the piping to the rads is laid out, but what I do know is that only 11 of the 17 rads can be turned off using the summer valve in the hot-press. The other 6 rads need to be isolated using their individual valves.

    My question is this - is it possible to configure our setup so that we can have zoned heating on the house? When I say zoned, I mean:
    1. Water only
    2. Downstairs heating
    3. Upstairs heating

    In layman's terms, what are the step we'd need to carry out? What equipment would need to be replaced (e.g. I know the timer will be no use, because it's only designed for a "one zone" system). Could we still use our existing boiler? What / if any changes would we need to make to our pipework?

    Any help greatly appreciated!

    The boiler can be kept, but the main pipework for the heating and hot water would have to be re-plumbed in order to achieve what you are looking for.
    This will most likely involve lifting floor boards, and if any of the pipework is under concrete floors, probably some digging up as well.
    In saying that, I did a job where none of that was required due to the layout of the house and the location of existing pipework, so you could be lucky.
    The only way you will know for sure is have someone call to take a look at it for you.
