    Hi guys new to the forum. I’ve landed on a job on a dental surgery. The plumbers have installed new heating and got water system and basically left me to wire it up. Struggling to get my head around it and could do with some help. They’ve installed two boilers that are going to work together, two pumps one for c/h one for h/w. There’s three zone valves two for downstairs and one for upstairs. There’s also a h/w cylinder with a cylinder stat. They then want three room stats for c/h two downstairs and one upstairs. Any would be appreciated cheers

    No valve for the H/W then?

    Are you a qualified sparky?

    Separate these zones and the hot water system and draw it out should be easier to get your head round

    The pump on the boiler for the hot water circuit is unusual because it's usually inside the boiler but maybe a secondary return.

    Draw it out on paper for the heating separate from the hot water just to divide and conquer and you will see its rather simple as it's all in series pal.

    You need to tell us.
    so you have 3 heating zones (2 downstairs 1 upstairs) each one with a valve and controlled by a room stat
    1 H/W zone valve controlled via tank stat.
    two pumps one for the system? one for secondary return?
    Is this correct?

    Hi Antony this is correct. They want each zone to have its own room stat if this is possible. Cheers

    Has any of this been wired or plumbed?
    Yes one room stat to each valve one tip ask the plumber which valve does which area and mark up each stat. Look at Lee's wiring diagram. Ask the plumber what each component does and post some photo's if possible.
