But having investigated I can't see any evidence of a feeder tank. The hot water cylinder seems to take its feed directly from the mains supply and is heated by the element within the tank.

Almost certainly related to the unusual outdoor temperature and pressure. Could also run the taps a littlehttps://community.betfair.com/chit_chat/go/thread/view/94038/30423821/hot-water-tank-overflow-outlet-query?post_id=543233961#543233961May just need a minor adjustment to the nut on the thread on the orange ball arm so the water shuts off at a slightly lower level in the tank.

Condensation alone unlikely to be the cause because the overflow pipe is cold and empty unless there's an overflow of hot water.I'm not 100% sure what the arrangement is here, as the tank is encased in a solid insulating jackhttps://community.betfair.com/chit_chat/go/thread/view/94038/30423821/hot-water-tank-overflow-outlet-query?post_id=543230249#543230249Many thanks for answers.
