Underfloor heating is bad for you as it promotes vanes in your legs and feet to grow too large and creates a lot of problems later in life. a better trade off is in wall heating and that is why the new ECO all in one lego houses use in wall heating systems.

Quite the opposite MSHunter research in the 70s concluded that underfloor heating was not a factor in varicose veins.
