How long does it take to raise 1 cubic ft of air 1 degree?

Answer 1

To raise 1 cubic foot of air by 1 degree Fahrenheit, it typically requires about 0.24 British thermal units (BTUs) of energy, assuming constant pressure and humidity. The actual time it takes depends on the power of the heating system being used. For example, a heater with a capacity of 1,000 BTUs per hour would raise that volume of air by 1 degree in approximately 14.4 minutes. However, factors like air circulation and insulation can also affect the time required.
