Hi all

I have a 1970s house which has stored domestic water tanks (x2) and central
heating header tank (all of which are round).
The sizes appear to be imperial @ 30" and 18" diameter respectively.
Does anyone know a source for suitable lids for these.
ATM they have sagging ply or formica-type covers with insulation thrown
over.
Since a CH upgrade the header tank is getting quite a bit hotter than
previously and I would rather not have hot water vapour condensing on the
roof trusses.

TIA

Phil
