Rad bracket fixing on tiled plasterboard

[nicam49]

Hi All! Am replacing a smaller imperial sized rad with a wider metric one. The old rad brackets are attached directly onto plasterboard with those anchors that you attach with a setting tool. The wall is now tiled with ceramic tiles , except where the brackets are. (I tiled around the brackets.) Question:- The new rad will need new brackets in a different place which will mean fitting them onto the face of the tiles.: I can't see how I can fit wall anchors over the tiles - there are teeth that dig into the plasterboard - also the force needed to set them might crack or split the tiles..... are there any alternative anchors I could use?
If there are any ideas, could you please give specific details of model and make, and pref. something I can buy from a shop rather than online....
Thanks!

You might have done better considering the radiator before tiling the wall......
You have a few choices;
Decide where your new brackets are going
Dremel or anglegrind (with diamond disc) a radiator-bracket shaped slot in the tiles. The top and bottom short cuts will be amusing but you shouldn't have signed up if you couldn't take a joke. DON'T cut into the plasterboard.
Remove bits of tile
Use your setting anchors
There ya go

Or use the existing fixings to secure 2 timber battens (or a sheet of decent ply) to the wall then fix your rad brackets to the ply.

Or drill big holes in the tiles and use Gripits

Or find the studs/noggins and use long screws to fix battens

Assuming it's a hollow wall ,plasterboard on studwork. Drill through the tiles and plasterboards and use spring toggles.

Or even a Fischer gravity toggle
