SUMMARY
1 BTU (British Thermal Unit) is defined as the amount of energy required to raise the temperature of 1 pound of water by 1°F. This principle applies equally in reverse; lowering the temperature of 1 pound of water by 1°F necessitates the removal of 1 BTU of energy. Therefore, the energy transfer involved in heating and cooling water is symmetrical, confirming that energy must be added to increase temperature and removed to decrease it.
