BTU (British Thermal Unit) refers to the thermal energy generated by gas equipment is measured by the energy generated per hour.

Technically, it is an amount of energy that can raise the temperature of a pound of water by one degree.

Users need to know that an average of 10,000 BTU can increase the temperature of approximately 500 square feet, depending on conditions such as floor level, windows, and ceiling height.

ArtFire fireplaces burn 40,000 BTU on average to generate heat energy, which can provide heating for about 30-40 pings of indoor space.
