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

Try Plumb Center, BES, basically a proper plumbers/builders merchant
rather than a shed.

The header tank shouldn't be getting hot maybe just a little warm
*if* there is lot of expansion to handle. Hot indicates circulation
through the header tank (pump over) which should not be happening.

I tried getting a lid years ago. The tanks were obsolete patterns, the
lids were not available and, even if they were, the plastic tanks
would have stretched in use to the extent that the lid wouldn't fit.
You cannot get a snap-tight seal, that is required to keep dirt out
and condensation drips in, with a fabricated lid. The lids were
probably used to mix plaster in. The only option is to fit new tanks.

Make sure they are continuously supported, preferably on WBP ply.

Actually *marine* ply is suggested! And 15mm thickness - never seen that.

Ase onetap says the correct way is to fit new tanks. Is that going to
happen?

On a planet closer to mine one might get some of that corrugated plastic
type stuff they make estate agents' signs out of (hmmm, wonder where you
could get that? ;-)[1]) and make a disc the right size and duct-tape it to
the tank. If you want to get fancy you could cut a smaller access hole in
the disc and make an overlapping cover, maybe velcro-ed on....

To fully comply with curent regs you would refit the overflow to the tank
with the gizmo with a fly-screen out of a byelaw-30-kit.


[1] actually you can get large sheets of it sold as temporary floor
protection during building work, from SELCO and doubtless elsewhere

Thanks to all

Can't see the tanks getting replaced, so it looks like the dustbin lid and
For-Sale-Sign solutions get my vote!

With "other solutions" think about where the condensation will run
to. A dust bin lid would need to ne used upside down other wise the
condensation will run down to the edge of the tank and by capilary
action down the outside of the tank. Similary a flat sheet but not
quite as bad.

I'm wondering is some poly sheet, heavier than bin liner but not as
heavy as floor DPC, would be better. With a small weight in the
middle to ensure that "down" is inside the tank, Fixed by binding
with string (if there is a suitable lip on the tank top edge or
possibly gaffer taped.

That's exactly what I've done - heavy duty polythene sheet from
Wickes, ring of duct tape round the tank 6 inches below the top. No
need to weight it, the sheet has enough sag in it to create a dip in
the centre.

if the CH header tank is getting warm maybe think about turning the
pump speed down a click.

Corrugated sheet will bow down in the middle so condensation will drop off
into the tank.
