N2 - The maximum temperatures reached by an insulated and an uninsulated underground rock bed were 52 degree C and 39 degree C, respectively. The insulated rock bed reached a quasi-steady state condition where each additional day's charging approximately equaled the heat losses occurring over a 24-hour period. The temperature profile, after reaching steady state, exhibited a harmonic response to the collector outlet temperature. Equations are derived to provide estimates of the average mean daily rock bed temperature at steady state and the thermal decay of the rock bed.
