We examine a one-dimensional circularly symmetric supergranulation reconnection model with typical quiet-Sun values. In this model, the assumed source rate of elements determines heating, because all emerged elements eventually annihilate; the assumed collision cross section determines mean field-the more efficient the interaction, the fewer elements exist at any time; and the effective element diffusivity determines the ratio of field strengths in the network and cell interior. Power-law indices for the variation of the heating flux with the mean magnetic field were computed in order to allow comparisons to observations. The indices are found to be in the range 1.9-2.0, and the only parameter that was found to have much effect on them was the effective element diffusivity, where the index declines roughly logarithmically with decreasing diffusivity. Even this effect is fairly shallow, however; a tenfold reduction in diffusivity only lowers the power-law index from 1.9 to 1.7.
