Heated flooring in the bathroom and kitchen

[Cambridge]

I am interested in having Heated flooring in the bathroom and kitchen, but in the kitchen I have the original mosaic tiles, how realistic it is to have the heating done with out damaging the original Victorian tiles ?

Is that a ground floor kitchen ?

Yes, it is. In the mean time I 've decided to have cast iron radiators instead of underfloor heating. The restoration process to relay the original tiles is too risky and expensive.
