What is the difference between radiant heat and radiators?

Radiant heat and radiators are two different types of heating systems. Radiant heat is a type of heating system that uses infrared radiation to heat objects in a room, such as furniture and people. This type of heating is often used in flooring systems, as the heat is distributed evenly throughout the room. Radiators, on the other hand, are a type of heating system that uses hot water or steam to heat the air in a room. Radiators are typically found in older homes and are not as efficient as radiant heat systems. Radiant heat systems are more energy efficient and provide a more comfortable environment.
