Radiant Ceiling Panel Calculator

How It Works

Radiant ceiling panels heat a room by emitting infrared radiation from panels mounted flush with or slightly below the ceiling. Unlike forced air systems that heat the air, radiant panels heat objects and people directly — similar to how sunlight warms you even when the air is cold. This means the room feels comfortable at a lower thermostat setting, typically 2 to 4 degrees lower than forced air, saving 10 to 15 percent on heating bills. The panels operate silently, have no moving parts, require no ductwork, and produce no dust circulation. Coverage typically ranges from 50 to 70 percent of the ceiling area depending on insulation — well-insulated rooms need less coverage. Each standard 2x4 foot panel produces about 375 watts and costs $200 to $350 plus installation. Operating costs depend on electricity rates, run time, and insulation quality. Radiant ceiling panels are best suited for supplemental heating, room additions, sunrooms, and homes without ductwork. They work well with high ceilings because the heat radiates downward to the occupied zone rather than stratifying at the ceiling like warm air does.
