If 80,000 BTUs are absorbed and 100,000 BTUs are supplied, what is the efficiency of the boiler?

To determine the efficiency of the boiler, the formula used is:

Efficiency (%) = (BTUs absorbed / BTUs supplied) x 100

In this scenario, the boiler absorbs 80,000 BTUs and is supplied with 100,000 BTUs. Plugging these values into the formula:

Efficiency (%) = (80,000 / 100,000) x 100 = 0.8 x 100 = 80%

This indicates that the boiler is effectively converting 80% of the energy supplied into useful energy absorbed, which is indicative of its operational performance, often expressed as a percentage.

This efficiency value reflects how well the boiler is utilizing the energy it receives, with 80% being a common standard for energy efficiency in heating systems. An efficiency of 80 is generally considered acceptable for many types of boilers, balancing effectiveness while highlighting areas for potential improvement in energy savings.
