If you've ever stepped barefoot onto a cold tile floor, you know that comfort partly depends on the temperature of the surfaces, furnishings, and objects you come into contact with. That's another reason why forced air underwhelms homeowners: If it warms anything else besides the air, it does so only to a modest degree. In pursuit of greater comfort, therefore, you turn the thermostat up higher and higher, risking unpleasant consequences for your household budget. That's why, for all-encompassing, "everywhere" warmth, industry experts increasingly recommend radiant heating. It's a technology that doesn't stop at warming the occupants of the home—it also warms everything else.
