What does horsepower (boiler) represent?

Horsepower (boiler) represents the thermal power needed to evaporate 34.5 pounds of water per hour at 212°F, measuring the steaming capacity of boilers.

Why convert horsepower (boiler) to Btu (IT)/hour?

Converting to Btu (IT)/hour allows expressing boiler power in a universal heat transfer unit widely used in HVAC and heating system design.

Can I use this conversion for all types of boilers?

The conversion is based on steam evaporation at 212°F, so it is most accurate for boilers operating under these standard conditions.
