Aluminum radiators worth it? Best place to buy?

They are also bloody ugly things looking at those pictures.

I thought the rad linked had a more efficient form for heating/moving the air through:

It's not really about the rad being more efficient per sé i.e how well a certain metal conducts heat from the water and then transfers that out, rather how efficiently it will heat the space it's there to heat, that's a whole different discussion.

Aluminium columns like the ones detailed, with their intricate internal airways could be more efficient at space heating than solid steel columns as it could be better @ create convection currents due to the way it channels heat in through and out. Convection is more efficient at space heating than radiation.

Is it worth the >30% extra in cost, depends on the client I guess.

Hi all,

Are aluminum rads worth the hype? Looking at a high output but they're obviously more expensive.

Looking at the following:

This is the BTU output the larges one at the bottom.

Also where is the best place for rads in general?

Thanks

Don't get the wrong idea about efficiency. Rads are all 100% efficient, as all the heat lost from the water goes into the room. Where they differ is in heat output, which depends on the size and type (single, double, with or w/o fins) etc.
IMO you should decide what output you need and choose a rad accordingly, making sure all the options are at the same water in/out temperatures. You can then decide which best suits your available space, and any other criteria.
BTW your table looks like column rads. That type seems to get a bad press on this forum.

It seems that Mr Baker has been taken in by "all this hype" which has no justification from any technical viewpoint.

If you want a higher heat output you fit a larger rad . That will be steel. And to be more efficient you would fit a conventional rectangular rad low down.
