 In this unit, fans blow across the tubes carrying the heated fluid, and the room is warmed as a result.This type of heater is popular since it reduces the fumes significantly and virtually eliminates the risk of carbon monoxide poisoning as well as the chance of a small child or pet accidentally injuring themselves.Electric heat is typically delivered through heat pump units mounted on the ceilings or the walls, such as above the doors to the deck or balcony, rather than through baseboards.
