Primatic cylinders were expensive. Although before poly F&E tanks and
they were zinc coated steel, it may have made some sense in equipment
purchase. It was just quicker to install, probably saving a little on
labour, if anything. I could never see the reason for them once poly
F&E tanks came about, and they are still sold.

Some makers say you can dose the CH, but only directly into a rad and
the inhibitor has to similar to X-100 or the harsher Fernox.

That brings back memories - I grew up
with a steel squarish one, about
3x3x1ft deep, that fitted neatly under
the airing cupboard.

An Elson, still made today.

Some time when I was away defending
queen and country, it got replaced by a
cylinder that didn't fit in the space.

Typical. The local idiot plumber looks at it, can't figure it out, or not
available at the local, plumbers shop and fits a cylinder. Elsons are great.
They are square and save space. They are mainly sell to developers for new
houses.

I have seen this with thermal stores too. In one instance the blending valve
had gone, the whole estate was fitted from new with them. All the idiot
plumber had to do was phone up Range and they would send one overnight for
around £25-35. The loony didn't understand thermal stores. He convinced
the householder to fit a tank in the loft, a cylinder and a power shower
pump at great expense, and athe shower was nowheer near what teh mains gave.
I would have taken the ******* to court. Apparently you can, and will win
in these situations. If he doesn't know what a thermal store is he
shouldn't be trading.

Prolly some mad scam/scheme by B-I-L
and his family; I never enquired about
those things
