My similar foamed tank is in the integral garage and I wondered
if there was any point in adding any extra insulation? There
isn't a lot of clearance, but I suppose I might drape something
over the top similar to the old jackets.

If it's in a cupboard the space can be packed with junk insulation, avoiding any flex feeding he immersion. If no cupboard it's easy to construct a flimsy outer wrap that can be stuffed with insulating junk, or apply roll insulation & tie.
