Radiant Underfloor heating works by having heating mats that fit under your flooring. These heating pads are temperature controlled by a simple to use thermostat. An average countertop (typical sized island) will be about $200-$300 depending on the size and width.

Installation is as easy as presetting a thinset of undercoating, Laying your underheating pads and connecting them to the thermostat and then setting your flooring or countertops overtop the undermat and installing them as usual.
