kilowattsthermal

Kilowattthermal is a unit of power commonly used in the context of heating and cooling systems, particularly in North America. It represents a specific rate of energy transfer, equivalent to 1,000 watts of thermal energy. While the watt is the standard SI unit for power, the kilowattthermal is often employed for practical applications involving building climate control. This unit helps to express the heating or cooling capacity of furnaces, air conditioners, boilers, and heat pumps in a more relatable scale for consumers and HVAC professionals.

The kilowattthermal is derived from the kilowatt, a unit of electrical power. However, it specifically quantifies thermal energy output or input. For instance, a furnace might be rated at 25 kilowattthermal, indicating its ability to generate 25,000 joules of heat per second. Similarly, an air conditioner could have a cooling capacity expressed in kilowattthermal. Understanding this unit is crucial for sizing equipment appropriately for a given space to ensure efficient and effective temperature regulation. It is important to distinguish kilowattthermal from kilowatt-hour (kWh), which is a unit of energy, not power.
