Radiant heat can be both good and bad, depending on the situation. On the plus side, radiant heat is very efficient and can provide a comfortable, even heat throughout a space. It is also very quiet and can be installed in a variety of ways, such as in the floor or ceiling. On the downside, radiant heat can be expensive to install and can be difficult to control. It can also be difficult to adjust the temperature in different areas of the space, as radiant heat is not as responsive as other heating systems.
