    The pilot light goes out during the night when the heating is off (hot water left on). Have to re-ignite every morning.
    Engineer been out 6/7 times, replaced various bits - pressure ok and expansion thingy replaced and jets and pilot light, thermo coupling new.
    HELP

    As Elvis has said; is the flue terminated in an exposed location.

    Also, has he replaced the gas valve??
