Red Seal Plumbing Complete 2025 Practice Exam

Question: 1 / 400

What does the net rating of a boiler indicate?

Maximum heat produced by the boiler

Amount of fuel consumed per hour

Amount of heat energy available at the heat transfer units

The net rating of a boiler indicates the maximum amount of heat energy available at the heat transfer units. This is different from the maximum heat produced by the boiler (option A), which does not take into account any potential losses in heat transfer. Option B, the amount of fuel consumed per hour, is not necessarily related to the net rating as it can vary based on factors such as efficiency and heating load. Option D, total energy consumption of the building, is also unrelated to the net rating as it includes energy usage from sources other than the boiler.
