HEAT STORED UNDER BUILDING CUTS OPERATING COTS

IN ORDER TO REDUCE HEATING COTS, SOME DESIGNERS HAVE TURNED TO A SYSTEM THAT USES ELECTRICITY TO STORE HEAT IN THE GROUND UNDER A BUILDING AT NIGHT-WHEN RATES ARE LOWER. IT THEN USES THE STORED HEAT THE NEXT DAY TO WARM THE BUILDING DURING PERIODS OF PEAK DEMAND WHEN RATES ARE HIGH. THE SYSTEM, CALLED DEEPHEAT, IS BEING USED IN COMMERCIAL AND INDUSTRIAL BUILDINGS AND NURSING HOMES. IT SAND UNDER THE CONCRETE FLOOR SLABS OF ONE-STORY STRUCTURES. ENERGIZED FOR ONLY SHORT PERIODS OF TIME DURING UTILITIES' NON-PEAK NIGHTTIME HOURS, THE SYSTEM CREATES A BALL OF HEAT IN THE SAND AND GROUND THAT RADIATES UPWARD THROUGH THE FLOOR DURING DAYTIME HOURS. THE SYSTEM'S CHIEF ADVANTAGE IS THAT AN OWNER ONLY- USES ELECTRICITY FOR HEATING PURCHASED AT ITS LOWEST RATES, SOMETIMES GAINING A 20 PERCENT TO 50 PERCENT REDUCTION FOR TOTAL ENERBY CHARGES. ARCHITECTS AND ENGINEERS FAMILIAR WITH THE SYSTEM SAY THAT THE HEAT RESEARVE IS SUFFICIENT TO MAINTAIN A LIVABLE WARMTH FOR FOUR OR FIVE DAYS, IF NECESSARY, IN THE EVENT OF A POWER INTERRUPTION.
