Calculates the heat loss to the ground from an evenly insulated rectangular slab on the ground. Both the heat loss variation during the year, including the peak effect, and the accumulated heat loss during the heating season are calculated. The effect of a sudden cold-spell may be analyzed.

The results are based on heat conduction in a semi-infinite ground with homogeneous soil. The effect of moisture movements or changes in moisture content is not considered. Screen Shots
