What does the acronym BTU stand for?

The acronym BTU stands for British Thermal Unit. A BTU is a measurement of energy used to quantify the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. This unit is commonly used in the field of heating, ventilation, and air conditioning (HVAC), as well as in other areas related to energy consumption and transfer. Understanding BTUs is essential for plumbing and HVAC professionals to assess heating systems, calculate energy costs, and ensure that systems are properly sized and efficient for their intended use. This foundational knowledge is crucial in providing effective and safe plumbing and heating solutions.
