Radiant Heating in Chicago — What Homeowners Should Know
How Radiant Floor Heating Works
Radiant floor heating circulates warm water through tubing embedded in or below the floor. The floor surface radiates heat upward, warming objects and people directly rather than heating air. This produces even, draft-free warmth from floor to ceiling — the most comfortable form of heating available. Water temperature is typically 85–140°F, much lower than a standard baseboard system.
Radiant vs. Forced Air
Forced air systems heat air and blow it through ducts, creating temperature stratification (hot near the ceiling, cooler at floor level) and circulating dust and allergens. Radiant systems heat the floor and objects in the room, producing even temperatures from floor to ceiling with no air movement. Radiant is quieter, more comfortable, and often more efficient for well-insulated homes.
Boiler Selection for Radiant Systems
Radiant floor systems operate at low water temperatures (85–120°F for most floors), which makes condensing boilers ideal — they achieve maximum efficiency at low return water temperatures. A standard atmospheric boiler running at low temperatures will condense in the heat exchanger, causing corrosion. D's Air specifies the correct boiler type for every radiant installation.
Zoning and Controls
Radiant systems are easily zoned — each room or area can have its own thermostat and zone valve. Proper zone design prevents overheating in one area while another is calling for heat. D's Air designs multi-zone radiant systems with manifolds, zone valves, and programmable thermostats for maximum comfort and efficiency.
