Heat Output Difference Between Finned/Unfinned Rads?

[plumbandplumber]

As an approx percentage, how much less heat would a single panel non-finned rad give compared to one the same size with convecting fins?

Many thanks.

30% ish

It depends on what you are comparing.

To compare modern rads - look up the difference between a P1 and a K1 on [DLMURL="http://ukweb.stelrad.com/uk/resources/files/b9f4facf41064b974ee7dc716fd5ca26/elite.pdf"]this stelrad list[/DLMURL] Its a bigger difference than you would think.

Historically, this would be less. Originally, the fins were welded to the gaps between the waterways. When they shifted to welding them directly to the waterways, the output increased massively - IIRC it was about 15%.

need to rename you "Sheldon"

Thanks to you both.

Quite surprising to see the difference between finned and unfinned rads in that catalogue. Eg. a 600x1400 single goes from 3000BTU to almost 5000BTU just by welding on some fins.

Surface area is king just like your guts.

This finned advantage may drop off with time ( 100s of dam spiders this year )

Is there a purpose made tool cleaning tool ?

 

[Howsie]

Yes. You can get them with or without bags.

Yes. You can get them with or without bags.

But who can find where attachments have gone !

( Drunkenly at m8s getting more heat from rad at XMAS , quietly late night with tissue and wooden dowel )
