ABSTRACT:
A steady state swimming pool heat exchanger designed to warm the water in swimming pools by the conducting of heat from the constant heat reservoir of the earth into the water in the pool through a heat-conducting rod sunk vertically into the earth beneath the pool. Attached to the rod is a contact plate, mounted on the floor of the pool, which transfers heat energy from the rod to the water. In temperate climates, the earth maintains a constant level of heat of 65 to 70 degrees at a depth of approximately 10 meters. The contact between the earth and the water in the pool provides a steady state transfer of heat to warm the water when the water temperature is below that of the earth reservoir. A non-conducting cover is provided to restrict the heat flux when heating or cooling of the water is not desired.
