Underfloor heating problem?

I can't see a problem. The surface area of the pan is a very small area of about .5 to 1cm, in a partial ring, of ceramic, with a huge air space and water area above. So long as the wires don't lie beneath the fixing holes, I'd be happy with warm feet when I go.

Yeah, this is what I was thinking. I can't see the bowl being a very good heat conductor. At worst it will probably make the heating less efficient.

Any experts out there who can confirm/ deny this!

What you actually want is a good conductor of heat, not a bad one. The heating will warm the floor, and warm the ceramic tiles. They then dissipate into the air above the tiles, and heat the room. A wooden bookcase, or sofa, or even a rug, is a very bad conductor of heat, and so increases the floor temperature to a level wheere the heating elements will suffer. A toilet pan, while not a good conducter, isn't as bad. So the base will warm gently, but has a large side surface area to dissapate the heat from. The air space inside the base will warm, but the water above it will act as a good heat sink, even if the pan is a modern one with a sealed base. Old style pans with an open base to the trap will have air circulation.

We've underfloor heating in all our bathrooms / ensuites, all have toilets floor mounted. No issue really. You're only losing a small amount of floorspace the to the base of the toilet.

Ours is a water based system, not electric, but i guess the principal is the same.
