Which statement regarding radiant heaters is incorrect?

Radiant heaters operate on the principle of radiative heat transfer, which is fundamentally different from conduction or convection. One of the key characteristics of radiant heat is that the intensity of the radiation diminishes with distance due to the inverse square law. This means that if an object is moved twice as far away from the heater, it will receive significantly less heat, not more. Specifically, the amount of radiant heat received decreases inversely with the square of the distance from the heater, leading to less than half the heat energy when the distance is doubled.

The other options reflect accurate statements about radiant heating. Radiant heaters primarily transfer heat through radiation rather than conduction, effectively emitting infrared radiation that warms objects in their path. Moreover, while heat does not increase proportionally with distance, radiant heaters are often applied successfully in heating spaces such as floors and ceilings, showcasing their versatility in various applications.
