Single to double radiator - microbore pipe extention

[Bill May]

10mm is good for about 3.5kW @ 20degC difference any larger rad and you won't get the output.

Understood - the new double is still smaller than the existing one so I’m working on the principle that is should hold good based on that.

Otherwise try using 10mm push fit street elbows (male - female ends)

Are you referring to these?

So presumable one into the TRV/lockshield and one on the editing pipe, and connect the two together and hope it bridges the distance.

Won’t look amazing but I’ve got at least two options to go at now.

Thanks everyone for the suggestions.

Or something like this might look a bit better, Bill ?
A little less chunky & C/P if your rad valves are.

Agreed.

Thanks a lot you have helped hugely.

Thanks Bill just a word of warning my link above is for 15mm male spigot to 10mm socket, I just spotted it sorry.
I am sure they do 10mm streets in C/P if your valves are 10mm & you wanted to put the two together to make a set.
