    Might be zones

    Might be balancing

    You can tell us more about your controls, and valves, and show pics.

    They will be fitted on your central heating Pipework . squarish shaped Box ( metal or white plastic ) with electric cable coming out of them ,to loosely describe them. You will have a number of them !

    It is indeed. How many of them can you find ? One of them will operate the rads that do not heat up and the pipe going into it will be hot and the pipe going out will be cold further along its length.

    This is the only cupboard in the house, I have a combi and no hot cylinder. The house is only 5 years old and every available space is a room such as the top and middle floors, there are no other voids or cupboards for another valve

    No two way valves under the combi?

    You would think the stats on the middle and top floors would drive two way valves?
