BPI Heating study guide
BPI Heating · Work through your exam, one topic at a time.
The Heating Professional credential is one of the certifications listed by the Building Performance Institute (BPI), a non-profit organization that describes its mission as advancing the home performance industry through nationally recognized standards and credentials, with the goal of making homes comfortable, healthy, safe, durable, and energy efficient. The Heating Professional designation appears on BPI's current certification roster alongside credentials such as Building Analyst, Energy Auditor, AC/Heat Pump, and Air Leakage Control Installer. The BPI Heating study guide has 5 sections and about 1,654 words.
01Heating System Fundamentals and Building Science
A heating system is a boundary problem: the enclosure creates the load and the equipment only meets it. Candidates should be fluent in conduction, convection, and radiation; in R-value (resistance) versus U-factor (conductance, U = 1/R); in thermal bridging through framing; and in the difference between the air barrier and the vapor retarder.

Methane plus oxygen yields carbon dioxide, water vapor, and heat. Stoichiometric combustion needs about 10 cubic feet of air per cubic foot of natural gas; real appliances run with excess air for safety.
336 words, about 2 min03Heating Equipment Inspection and Installation Review
Every inspection starts with the nameplate: input and output ratings, gas type, vent category, clearances, and required combustion air. Vent category drives material and pressure: Category I appliances vent under negative pressure with listed metal vent, while condensing Category IV appliances use positive pressure and often PVC or CPVC.

Combustion analysis gives oxygen or carbon dioxide, carbon monoxide, stack temperature, and net stack temperature, from which steady-state efficiency is derived. Temperature rise is supply air minus return air at steady state, compared to the nameplate range.
322 words, about 2 min05Distribution Systems, Controls, and Documentation
Distribution delivers the Btu the equipment produces. Duct systems are designed around available static pressure and total effective length; the friction rate is available static pressure divided by total effective length, and every fitting adds equivalent length.
