What the convention actually is
It is the brand name of a heat-resistant coating applied to steel flue components and stove bodies. On the German market it has drifted into use as a common noun: a listing says a pipe is coated in it the way a listing elsewhere might say a component is anodised.
What the word usefully tells a buyer is that the component is a coated steel article rather than a bare or galvanised one, and that the finish is intended to survive the temperatures a flue reaches. That is genuinely worth knowing on a shelf where the alternative is aluminised steel with a very different appearance and a different working life in a room.
What it is not is a classification. It appears in no designation, and it is not what any standard asks a product to declare.
What it does not promise
It does not tell you the product’s temperature class, its pressure class, its corrosion resistance class or its assessed distance to combustible material. Those are the declared characteristics, and they are absent from a great many listings that print the coating name prominently.
It does not distinguish a genuine application of that coating from a description used loosely, and this site has no way to verify which a given listing means.
And it says nothing about wall thickness, which on the connecting pipe shelf is the other property sellers lead with and the one that actually differs between the cheap article and the heavy one.
The documents that sit beside it
A flue component’s real declaration is the designation described by the general chimney standard, supplied by the metal chimney product standard. Where a listing prints both the coating name and a designation, the designation is what the page leads with.
The stove paint family exists on this site partly because of this convention: the aerosol sold to touch up a stove or a pipe is frequently described with the same word, and the buyer is choosing between products that are not all the same thing.
Where it appears on this site
On the connecting pipe and elbow families above all, where the survey behind this site found the word in dozens of titles, and on the stove paint family.
The page exists because the word looks exactly like a standard in a listing full of standards, and a reader who takes it for one comes away believing a product declared something it never declared.
Questions that keep arriving by post
Is a coated pipe better than an aluminised one?
They are different articles with different finishes and different appearances in a room. What separates two flue products in the sense that matters is their declaration — temperature class, corrosion class, assessed clearance — and the coating name is not part of it.
Can I repaint a pipe with ordinary heat-resistant aerosol?
The stove paint family on this site is exactly that shelf, and the products differ in the temperature they state and in whether they are intended for a firebox exterior or a flue. What a particular manufacturer permits on its own appliance is in its instructions.
Why does this site treat a brand as a standards page?
Because the group it sits in is for conventions the trade uses as if they were standards. Putting it beside the real documents, and saying it has no publisher, is the only way to show a reader the difference.
