Electric
furnaces come in a variety of configurations and are similar to the more common
gas-forced air furnaces. Most electric furnaces are multi-flow units (meaning
that the same unit can be positioned in a variety of ways: upflow, downflow,
or horizontal).
Compared to electric baseboard heating systems, forced-air electric furnaces provide the advantage of a centralized air handling system with air filtration, humidification, and control of air distribution.
The additional installed cost of a central electric furnace system over a zonal
heating system is probably justified in only two instances if you will be:
-
Filtering the Air, or
-
Installing a Central Cooling System.
