A heating appliance designed for garages, typically fueled by natural gas or propane, with a heat output rating of 45,000 British Thermal Units (BTUs) per hour. This specification indicates the amount of energy the unit can deliver in the form of heat over that period. For instance, such a heater is often employed in spaces where maintaining a comfortable working temperature is crucial during colder months.
The significance of this heating capacity lies in its ability to efficiently warm relatively large or poorly insulated areas. Garages often lack the insulation found in living spaces, making a higher BTU output necessary to achieve and maintain a desired temperature. Historically, solutions for garage heating were often inefficient or unsafe; modern units with a specific BTU rating offer a more controlled and effective approach.
