<p>HEAT LOSS CONTROL SYSTEM FOR BUILDING HEAT SUMPS A heat loss control system for a building having a sump of fill material which is heated by an electric heating cable, and a floor disposed on the fill material. A layer of porous material such as coarse sand having air spaces therein is disposed between the fill material and the earth, and a system of perforated tubes or the like is disposed in said layer,and water in the layer is removed by a pump attached to the perforated tubes. As the water is removed from the layer, air fills the porous material and forms an effective insulation to prevent the heat in the fill material from being dissipated into the earth beneath the sump. The heating cable may be disposed in the fill material or in the floor supported by the fill material. Probes are preferably inserted in the layer and connected either to a gauge or to the motor for the pump, so that the pump will be operated when it is necessary to remove the moisture and improve the insulating characteristics of the layer. 1.</p> |
