Identify a NOT listed space heating distribution system.

• A. Forced air
• B. Hydronic with radiators or convectors
• C. Steam with radiators or convectors
• D. Inductive heating

Answer: (D)

Understanding how space heat is distributed in a building helps you distinguish common HVAC methods from other heating technologies. The typical distribution methods deliver heat through air or circulating fluids: forced air moves heated air via a network of ducts; hydronic systems circulate hot water to radiators or convectors; steam systems generate steam that travels through pipes to radiators or convectors. Inductive heating, on the other hand, heats materials using electromagnetic induction. It heats conductive loads directly and isn’t a method for distributing warm air or warm water through a building to heat rooms. Because it doesn’t form a building-wide distribution network for space heating, it isn’t considered a standard space heating distribution system.
