What is not a basic component of a hydronic heating system?

• A. Cooling resistors
• B. Boiler
• C. Radiator
• D. Circulator pump

Answer: (A)

Hydronic heating moves heated water through a closed loop to deliver warmth. The essential pieces are the heat source (a boiler or other heater) that heats the water, the circulator pump that pushes the water through the piping, and the heat emitters (such as radiators or baseboard units) that release that heat into the rooms. A cooling resistor does not fit into this basic setup because hydronic systems rely on circulating hot water to transfer heat; electrical resistors that dissipate energy as heat aren’t part of the heat delivery path. In other words, the system’s job is to heat water, move it, and transfer that heat to the spaces, not to dissipate heat through a resistor. Optional but common add-ons include expansion tanks and valves for control, but the core trio is the boiler, the pump, and the radiators.
