Radiant heat is a type of heating system that uses infrared radiation to warm objects and surfaces in a room. There are three main types of radiant heat: electric radiant heat, hydronic radiant heat, and air-heated radiant heat.
Electric radiant heat uses electric resistance elements to generate heat, which is then transferred to the floor or walls of the room. Hydronic radiant heat uses hot water circulated through tubes to heat the floor or walls. Air-heated radiant heat uses air heated by a furnace to warm the floor or walls. All three types of radiant heat are efficient and cost-effective ways to heat a room.
