About BTU

This unit is widely used in the United States and some other countries for measuring the heating or cooling capacity of various systems, including furnaces, air conditioners, and heaters. uk You can see how our Marley Modern Vent Tile works in the image to the left (or above if you're on mobile). It's a measure of the amount of heat energy required to raise the temperature of one pound of water by one degree Fahrenheit at a constant pressure. This is helpful to know roughly how much heat will be lost to the surroundings.
