Fitting spotlights to a ceiling with ESWA ceiling heating

[stophden]

Hi,

I've just moved into a new flat, which has ESWA ceiling heating installed.

I'd like to replace the existing pendant lights with spotlights - have just purchased this.

When I opened up the box I realised I'd have to screw it to the wall, but on my thermostat it says not to pierce the ceiling.

However, there is a a spotlight plate already in the Kitchen.

Does this mean I can drill into the ceiling up to a certain depth, or is there another type of fitting for spotlight plates I can buy?

Any help?

That makes sense, if you've got ceiling heating. Which doesn't make sense (ceiling heating, I mean), as hot air rises. If you have a flat below you you've also got underfloor heating paid for by them.

A more bonkers system it's hard to imagine.

Does this mean I can drill into the ceiling up to a certain depth,

More likely to mean that, in the same way people tend not to have CH radiators in the kitchen, you don't have ceiling heating there.

What are your existing ceiling lights in other rooms like.

What you must not do is pierce the heating foils.
Ideally you need to be hitting the joists with the fixing screws or if your luck the fixing points maybe the same as the existing fitting.
It's possible that the installer of the heating system, has made provisions and left enough space to allow for replacement/upgraded fittings of different sizes to be installed.
But would not bank on it!
Is there by any chance that a ceiling plan of the installation was left, with any electrical documents that belong to the house? or do you have the contact details of the installer? as they should know.

Thanks for your help.

All of the other rooms have standard pendant lights.

I'll see if I can find a plan or the installer's contact details.
