Radiant heat vs forced air Radiant heat creates a direct heat emitting from the floor of your structure creating an even heat that radiates upwards keeping the heat where you need it the most. Forced air drives the heat straight upward and creates a warm ceiling. But unless you plan to walk upside down, all that expensive heat is wasted heating your attic!   Kennell's Radiant Heat - Serving the areas of Idaho, Washington, and Montana
