Among all the heating alternatives for a home, heaters and furnaces are probably the most familiar terms. Many people refer to their heating devices as furnaces, although a furnace is not the same as a heater.
A heater's ultimate function is to heat a room. This device is installed in the attic, basement, or machine room, from which it can distribute hot air throughout the space through air ducts.
A furnace can fulfill the same functions as a heater. However, the heater appears more energy-efficient than the furnace, implying that it is more cost-effective.
