In what unit is an inline electric duct heater measured?

An inline electric duct heater is typically measured in kilowatts (KW), which signifies the rate of energy transfer. Kilowatts are a more manageable unit for the typical heating output of electric duct heaters, as they indicate how much energy is consumed or produced in one hour. This is particularly important for HVAC systems, as it allows for easy calculations of energy consumption and system efficiency when sizing and selecting heating equipment for various applications.

Understanding that electric duct heaters convert electrical energy into heat, measuring their capacity in kilowatts is standard practice, as it aligns with the electrical load calculations often required for HVAC design. Using kilowatts provides a direct correlation between energy use and heat output, making it easier for technicians and engineers to assess the system's performance and compliance with energy efficiency standards.
