Aluminium ones are lighter, give out more btu and are much cheaper than similar sized steel ones.

Are there any down sides to using them?

Thanks

dpb

You service them with warmth as well...!

Dingdongler

Explain please?

dpb

Sorry Ding slightly tired joke about what should be provided for tenants, after all tdw nonsense

Cost more than they are worth.

The standard one works well at over 400bhp, why not use it?

Dingdongler

Oh I see

It's for my own house though.

I'm being extra dim today but you'll have to explain that one to me as well

I was assuming a car rad...is that not what we are talking about?

Aluminum is a better heat conductor if coloured(anodised) than bare aluminium. Prone to stress cracking if not mounted properly. Expensive compared to OE

Ding, not going for those lovely anthracite vertical rads then?

Dingdongler

I think they are aluminium chip!

I ordered two (different style)from that website but in white. They arrived and have been fitted but because they are alu' they felt really light and even a little flimsy.

I need more and was just worried that I might be making a false economy as though they are very reasonable priced no point if they'll need replacing in a few years.

Mine are deffo not aluminium, took two of us to lift them into place.

I would be cautious of adding an aluminium alloy radiator to a system which has steel radiators in the system, this adds another metal to the 'chemistry' of the system - i dont know what the risks for corrosion are but would research them carefully.

I think I read a while ago, that aluminium alloy raditators are designed for use with condensing boilers, which are more efficient when run at lower temperatures. I think greater heat output can be generated with less effort from the boiler if the whole system uses aluminium radiators.

I thought Subaru's were air cooled ? I use underfloor heating in the footwells controlled by the aircon

TT is correct in para 1. Galvanic corrosion concern.
