Abstract
An electrical heating system for building structures in which side walls form a space for fill material supporting a slab floor and containing an electrical heating cable, the fill material functioning as a heat sump for absorbing heat while the heating cable is in operation and releasing it over a period of time whether the cable is operating or not. A moisture regulator is included in the system consisting of one or more distribution units connected to a source of water and a probe sensing the amount of moisture for registering on a gauge or for operating a valve in the line for maintaining the desired amount of moisture in the fill material. The fill material may be divided by a plurality of vertical walls into compartments, and a water distributing unit and a moisture sensor probe are disposed in each of the compartments for controlling the moisture in each compartment. A thermal and moisture insulating material is preferably disposed between the fill material and the earth to prevent escape downwardly of the heat generated in the fill material and to assist in controlling the moisture content of the fill material.
