Hanging radiator on lath and plaster wall

[andyv1]

I have a small 60x60 cm radiator on my kitchen wall. This is an outside wall, at least 150 years old with 2 layers of brick and a lath and plaster inner liner. I hung the radiator using spring out plasterboard fastenings, but a visitor has accidentally fallen and partially dislodged it, damaging the plaster and some of the laths. I’ve considered screwing a sheet of ply on the wall with lots of fastenings then screwing the rad to that, but it would look a bit odd.

Does anybody have any ideas how I could attach solidly to the brick wall underneath? The catch is that you have to go through 9 cm of plaster, lath and fresh air before you get there. I’m not keen on significantly enlarging the holes to get to the brick.

Or any other ideas?

What are the laths attached to? They are usually attached to studs and if you can find the studs you can attach batons to the studs (which can be inset into the plaster if you want) that in turn you can attach your radiator to.

if you cannot find the timbers to which the laths are pinned or they are nowhere near where you need them.
remove 4 4”square sections out of the wall using a multitool. screw 2 4x4x2 squares into the brickwork behind each void and hang the brackets on them.

you can easily find the studs using my Special Tool.

Genius. I’ve now found the studs using my own Special Tool (a length of 2.5 mm cable) and have cut out a small section of plaster to expose them. None are quite in the right place. I’m torn between cutting a couple of horizontal channels and fitting battens across, or removing a few short lengths of lath and screwing 4 lumps of wood into the wall. The plaster is rather delicate, so minimum disturbance is called for.

Thanks for the prompt responses.

Third option, a sheet of 15mm ply, cut to a size a little smaller than the radiator, fix that where you intend fixing the radiator, to the studs in sever places, then paint to match the wall. That will be very secure.

4th option- resin anchors and M12 studding. Done this on internally insulated wall hanging a 1200 x 600 double rad
