Which of the following is NOT a type of heating system?

1. Hydronic

2. Steam radiant

3. Convection

4. Radiant heat

The correct answer is: Convection

Convection is not classified as a distinct type of heating system in the same way as the other options. Hydronic systems utilize hot water circulated through pipes to provide heat. Steam radiant systems generate steam that moves through pipes to heat spaces. Radiant heat systems typically involve the transfer of heat through surfaces, such as heated floors or walls. In contrast, convection refers to the process of heat transfer through the movement of fluids (like air or water), and while convection plays a crucial role in how heat is distributed in a space, it does not represent a standalone heating system. Therefore, it’s accurate to say that convection is a mechanism of heat transfer rather than a specific heating system. This distinction is key for understanding different heating strategies in residential and commercial settings.
