I see two solutions--

heat the ceiling of the electrical vault--

Seal the granite in that - This company makes some of the best sealers---contact them for suggestions---

The simplest might be electric heating mats designed to go under ceramic tile---but stuck to the underside of the floor using thinset .

Google search for 'ceramic tile heating mat'----

You will want to find one for your countries electrical voltage----Also--the low voltage systems will give you 20 years or more of service---

The 110 or 220 volt systems can burn out in 5 or 6 years----

This is a fun problem for me---not so fun for you!

Around here we have ice and snow to deal with---so heated slabs are common---

Sometimes tubes are placed into the concrete and hot water is used----other times electrical elements are used---

tiles often have heat mats or wires set into the thinset under the tiles---

I assumed that you do not wish to remove the granite if possible----

Now what country are we in?

Mike you know all those guys over the pond.

Doesn't sound like DIY to me.
