Tall column radiators

Options
We have a 400 w x 600 h double panel radiator connected by 8mm pipework. It works absolutely fine , we are having a bit of a blitz on the house and i have had a request !!! from my partner to change it to one of the modern tall radiators, a single panel type 400 w by about 1500 h. i'm quite capable of changing it after replacing several radiators  in our previous house. The new one is about the same BTU output as the radiator we have now , my question my sound a bit stupid, will the 8mm pipework be ok with this much taller radiator. Any advice appreciated

    Same BTU / kW radiator then the same pipes will be perfect.  Likely capable of a bit more if needed.

    Precise heat carrying capacity of any microbore pipework will depend on size, proximity to the distribution manifold, flow rates and temperature drop across in/out of the radiator...  One Google suggested 8 mm pipe can carry 0.49 to 2.48 kW (1672-8462 BTU) for 0.3 to1.5 m/s flow velocity and an 11°C drop.   Note that lower flow rates (<1) are recommended to keep noise down.

    Thanks ,that's more than enough for the new column radiator. only thing i can recollect is when we had builders in to do alterations to kitchen they dropped the whole ceiling and just up above the radiator there were a couple of 15mm pipes with tees on the end feeding a bedroom radiator and this one below. I am pretty certain it will all be ok now.
