The Master® electric fan space heater is turbo-charged. It has just one heat and one fan setting, and that setting is “effective,” which delivers clean, quiet heat. This heater gives you heat where you want it, because it doesn’t require ventilation and it’ll heat any area up to 165 square feet on 120V power. Think of it in localized indoor spaces like garages, workshops and warehouses. It’s a simple and sturdy unit that’s easy to move and easy to use. Master – built for power.
