Radiators – Alloy Vs Old School Copper

[v8s4me]

Overall the rads are the same size but the alloy rad has 41 rows of single channels measuring 2mm x 40mm compared with the copper one which has 46 rows of triple channels each measuring 3mm x 13mm.












I can’t do all the maths but on the face of it the copper one has significantly more surface area than the ally one so, unless alloy is a significantly better conductor than copper (it isn't is it?), then it looks like the good old fashioned copper rad is better at cooling than the alloy one. Let the debate begin…..

Decided to have the copper one recored rather than go for ally.....

Copper is a significantly better conductor than alloy, but it is something like 4 times as expensive so it isn't viable as a radiator material any more.......

Paul - did the re-core firm use a new copper core or some other metal?
