Electric baseboard heaters are quite common, specially in places where electric power is notably cheaper. These heaters are popularly installed in older houses where refurbishment of the old ducting and boiler system will be particularly expensive. They are also a favorite heating application for houses with rooms that do not all have to be heated at once, negating a larger centralized system. Of course, since these will be used to heat just a specific area at a time, careful measurements of the room and the required heating power will have to be considered. Advantages of electric baseboard heaters include lower initial installation costs, lower to no maintenance costs, quieter operation and faster heating times. Since a single heater unit will be used to heat a specific room or area of the house, no expensive ducting or piping will need to be installed within the woodwork or masonry. Individual heaters contain no filters that need to be periodically maintained, and when one unit does conk out, only the faulty unit needs to be replaced.
