A forced air heater works on a similar principle as your furnace, blowing warm air into the space needing heat. Forced air heating will provide similar comfort as your home allowing you to use your garage during the coldest days of the year.
Forced air heaters are much quieter than older models and will provide even temperature distribution.
A forced air heater offers more flexibility when installing a heater compared to radiant heaters, and they can directly vent through the roof or out the side wall of a garage.
A forced air heater costs more to operate than a radiant heater. When the garage door is opened most of the heat will escape which requires the heater to reheat the entire area again.
