Buderus & Dianorm radiators

roundrightfarm

I'm considering both these radiators and am having trouble telling if there is any difference at all in their build quality, but I don't have them right in front of me for comparison. They appear to be identical- same integrated valve, same attachments, same appearance, same nomenclature (Type 22, type 33, etc.)

Has anyone worked with these and can tell me if there is a quality difference, or is this an example of two different manufacturers ordering their parts from a single supplier and price should be my only consideration?

I've worked with the Buderus rads a bit but more so the Hydronic Alternatives rads. In my most humble of opinions I suspect they're all the same.

I also have worked with both and believe they come out of the same factory.
I have had customers that feel they project from the wall too far.
The runtal panel radiators are more streamline and the actually hang of the wall.

Both Buderus and Dianorm are very similar. They each use a different style TRV head. At last count, there were more than a dozen companies producing the pressed steel radiators in Europe. At least 3 are imported into N. America.

I also have used 3 different Panels rads. I have Buderus in my home. I currently use Biasi and Hydronic alternatives. Quality is all about the same. Biasi is pricewise a better value. The Hydronic alternatives versions have a greater selection in size and shape.
33 series is going to be hard to get in Buderus... long wait from Germany.

I had thought the Hydronic Alternatives rads were Buderus. Am I wrong about that?

Not the same... although similar.
