What does BTU stand for?

BTU stands for British Thermal Unit, which is a unit of measurement used to quantify the amount of heat energy. Specifically, it is defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit at a constant pressure. This measurement is important in fields such as heating, ventilation, and air conditioning (HVAC), as it helps engineers and technicians determine energy requirements for heating systems and boilers. Understanding BTUs is crucial for ensuring that appliances and systems are appropriately designed and operated to meet energy efficiency standards while effectively providing the necessary heating or cooling.
