Hot water cylinder leak

[BartC]

Seem to be finding leaks everywhere today.

This one is near the top of a hot water cylinder. Just a trickle, but it might have been there a while as there's all sorts of encrusted gunge around it. (Perhaps the results of an earlier fix.)

What's the best short-term fix? The cylinder will probably be replaced in the next couple of months, but it's leaking now, and starting to cause a problem on the ceiling below!

I don't mind if it's a bodge, and I can probably part-drain the cylinder if necessary. Plumbers Mait? But I can't see how that can stay in place.

Plumbers epoxy putty, carried by Screwfix and others. Sticks happily to damp surfaces, will even seal and set against pinhole / tiny crack at modest pressure (assuming this isn't a mains pressure cylinder). Stick of stuff about 20 mm dia 100 mm long, cut off a suitable length, knead it with fingers, stick in place. Every plumbing toolbox should have one!

I'd go with epoxy. Clean the surface thoroughly before applying. If you have a bit of glass fibre, it would help.

Pretty sure I've seen something like that in the 99p Store or Poundland.

Get a combi and get rid of this space consuming nonsense. Try an Intergas or Atmos... 2nd an Avantaplus or an ATAG if you have money.
