what size (output rads to get)

[Nefertari]

Hi,

I need 2 rads in my sitting/dining room moved to the opposite wall. whilst i'm having this done, I want to replace the rads as the current ones don't even have valves on.

How do I know what size new rads to get for the room please?

The room measures 7.29m x 3.56. if this helps.

Without getting too technical use this
http://www.trademate.co.uk/Services/HeatLoss/default.asp?_brand=CP
Just fill in what it asks.
It will give you a heatloss in watts and btu's

Then look at this about 1/3rd way down
http://www.stelrad.com/UK/docs/compact.pdf
and pick a radiator(s) to match the heatloss, rounding up.
eg heatloss 2120watts - rad size 600 x 1400 K2
or 1 @ 600 x 800 K2 + 1 @ 450 x 1000 K1 or whatever combination suits you best.
