What does horsepower (boiler) measure?

Horsepower (boiler) measures the rate of heat needed to evaporate a set amount of water per hour at 212°F, reflecting steam boiler capacity.

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

Converting allows easier comparison and specification of heat output using a widely recognized thermal power unit used in HVAC and heating systems.

Are the conversion results always precise?

Results assume steady state conditions and standardized references; varying operational factors may affect exact values.
