    It's probably acting as a 'boiler balancing valve' (bypass) and I'd recommend you leave it well alone for now.
    Belongs in the plumbing forum really.

    Hi all, I've just purchased a property which has been sat empty for months and months. Currently having a new kitchen installed, rewire, new rads ect and came across this gate valve I think it is... When I've got the heating and hot water on, the hot water seems to take ages to heat up. I'm wondering if it's anything to do with this? Should this gate valve be fully open or fully closed? Thank you

    Looks like it could be a by-pass valve or indeed the cold feed from the cold water storage cistern. Does it get hot at any point?

    It'll be a manual bypass, was typically used in older systems. You'd need someone experienced to set it up, or get an auto-bypass installed. Again by someone that knows how to set it up for the boiler/pump setup you have.

    Looks to me like it could be on the return from the coil to throttle the flow down. The more you close the valve the quicker the hot water should heat up, in theory. Try having it just a few turns open and see what happens. If you close it fully the hot water won't heat at all.
