What is the best method for sealing an immersion heater
into its heater boss?

Patience.

Used Boss Green last night but it still seems to be weeping
a bit.

Catch any drips. See if it is still weeping next weekend.



Make sure both surfaces are clean and flat. Make sure the sealing gasket
is even and isn't distorted in any way.

Put a smear of leak sealant, smells like silicone sealant, much the same
thing, and tighten up but take care not to take the thin copper plate of
the hot water tank with you and all I've done that way have been fine
