Sorry, but I'm not plain wrong there! If you review my post and the OP's then you will see no mention of underfloor heating. I'm comparing like with like and not adding UFH to make cold tiles warm!!
Your problems with wooden flooring had nothing to do with how cold it was - so you've gone a bit off the point..
No, I'm not wrong read your own post - you said you wouldn't buy a house with tile floors because they were cold - buy/sell has nothing to do with OP's post.......
