Imagine stepping out of bed onto a warm floor

Radiant heat is the way of the world in Europe and Australia. I am hoping my mother is never cold when she visits. The red tubes you see are attached to the rebar. In those tubes will be a constant flow of warm water set at a desired temperature. All the tubes run to a central location in the garage to the water heater. There will probably be 3 zones which can all be regulated at their own temperature. Can you believe this !! it even runs under the shower and the tub to keep the bathroom warm and dry.
