    I've been asked to investigate pressure loss in a heating system.

    Pressure relief valve is ok.
    Expansion vessel is OK.
    Boiler heat exchanger is OK, plus it's a new boiler anyway.

    Cannot see leaks under the floors. But there is one screed floor with one radiator. The pipes are copper in a plastic sleeving. The start and end of the sleeving is visible, so would have thought water would have been seen coming from there if it were those pipes.

    It is a slow leak anyway, but can be seen on the gauge with the pressure loss.

    So, non invasive electronic leak detection type people time?

    Have you tried turning the boiler valves off to see if the boiler is leaking ?

    Can you not do as Shaun said to prove whether it is Boiler or Heating then if it's Heating, cap off that section under screed and test again?

    As above , had it own home recently .Under laminate floor as well.
    Small pressure loss isolaTed boiler to prove it was circuit.

    Had leaks all over the circuit so ended up doing a full repipe via insurance claim.

    Normally quickest, cheapest and most definite way!

    Seen good results of leak detection with a thermal imaging camera. good excuse to buy one, then a very useful bit of kit for flushing, fault detection, damp detection, insulation etc
