Best way to make pipes fit radiator

[Growler]

Hi guys.
The rad in the pic (hope it works) is 600 x 600 and I want to put a 900 wide one there instead but obviously the pipes want re-arranging.
As you can see, they've been done before and they're under concrete, so how should it really be done without digging the floor up?

I would just do it as it's done now. If your new rad lines up with the old one at one end then you only need to make adjustment to the other end. I would disconnect at the first 90 degree coming out of the floor (you'll need a blowtorch if you want to keep the heights the same) and make up a new connection piece.

Thanks StephenW

And you`ll need to get the water out of the pipes lower than the drain cock to use a soldered fitting
