Radiator output comparisons

[rich42]

I am looking to replace two kitchen radiators. They are Ferrolli 600wide and 900wide by 700 high, single panel with fins. The current Ferrolli data on their web site does not mention the same exact size of my radiators in their heat output tables.

So I have taken the figures for current production radiators either size of my sizes and estimated an output figure in between

Is this a viable method to get the heat output, or do radiators differ much?

Kind regards, Rich

Yes, it is viable.

Its not totaly accurate, but generaly it will tell you what you need to know, ie, a single panel with fins of X size, will normaly only be a couple hundred watts at the very most different to another brand.

But this doesnt apply to any towel rail/designer rad types as they generaly give out a terribly low heat regardless fo size.
