    So house with boiler and pump in garage

    Power comes from house heating controls out to garage to fire boiler

    I'm now adding 2 radiators upstairs in garage and plumber is adding motorized valve and seperate pump

    So heating feed to boiler is on RCD on House board

    Garage heating controls are fed from Garage board on its own RCD

    What I'm looking for is your opinion on what way to wire it....

    I suspect a relay will be needed????

    Thanks is advance

    What I think you are saying is that the new heating controls will be on one circuit and the boiler they are to fire will be on another. If so using a relay would be a good solution.

    Yes however will there be a problem as both heating systems will be fed from seperate boards and seperate RCD's so might be a tripping issue?

      Not a problem if a relay is used. The coil from the relay can be fed from one source and the contact from the other.

      The 2 circuits will be isolated from each other through use of the relay.

      I would check that that the isolating switch for the garage breaks the control circuit from the house, important.Theres ways of doing that.

      Mark the separate control circuits and ensure proper isolation at the boiler
