changing radiators

[djc123]

Hi all
I have a new build property with microbore central heating. I want to change a bog standard Myers bathroom radiator for a designer one. The size is 641(w)*530(h). Do I have to replace it with one of the exact width or is there a bit of flexibility with the microbore pipe?
Thanks

By designer, do you mean a towel warmer/rad?

I don't understand what you mean by flexibility. You may be able to bend the microbore slightly to line up with new valves, but if you try a tight radius, you will kink it rendering it scrap. The scope for adjusting microbore for different valve positions is limited. Soldering extra bits on can look untidy.

If its a towel rad and you have floor boards, the neatest way is to take chrome 15mm pipes from the bottom of the rad, through the floor boards, and join to the microbore underneath.

The most important thing is to size the rad correctly to the room, to ensure that it will be man enough to heat it properly. Also, be warned that towel warmers can have pathetic heat output, so a single one won't be enough for a large bathroom.

Thanks for the info.
Iwant to replace it with a towel warmer.
The microbore comes down the wall behind the plaster.
With a width of 641 how can I get an exact relacement?
Thanks again.

You might just get away with a 700mm width towel rad.

Had a look at a couple, and the pipe centres are around the 650 mark.

If you are re-tiling, then you could dig a pipe out, and change it to whatever you want.
