It's certainly normal for Delta Therm and quite possibly for other makes too. I think my old Aquael heater had it too although it was hard to see. It's certainly never caused a problem for me and I can't see it causing a fire (it's underwater!) or tripping your electrics, especially with UK fused plugs. If anything it will blow the fuse in the plug long before it trips your electrics, but even that is unlikely. It's just humidity from the factory which is sealed inside the tube, and not a sign of leakage. It made me a bit nervous the first time I saw it, but I've since learned it's nothing to worry about.
