This rugged electric heater with an adjustable thermostat keeps the space warm. It is equipped with 5 settings including steady heat to high output for maximum heat and circulation. The anti-freeze setting is a great winter storage solution that automatically turns on when the weather drops to 38°F (3°C), ensuring the air temperature in the room remains above the freezing point. Solid steel housing and low profile design make it easy to store when not in use.
