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.

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

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