GEOTHERMAL HEATING AND COOLING
www.hws.eduheat stored water like a conventional hot water tank requires. Types of Systems Geothermal systems use the earth as a heat source and heat sink. A series of pipes, commonly called a "loop," carry a fluid used to connect the geothermal system's heat pump to the earth. Closed and Open Loops There are two basic types of loops: closed and open.

Cold Weather Safety Tips
www.weather.govTo keep pipes from freezing on an outside wall: 1. Let hot and cold water trickle or drip at night from a faucet. 2. Open cabinet doors to allow more heat to get to un-insulated pipes under a sink or near an outer wall. 3. Make sure heat is left on and set no lower than 55 degrees. 4.

Mechanisms of Heat Transfer - University of Oklahoma
www.ou.eduHEAT TRANSFER Mechanisms of Heat Transfer: (1) Conduction where Q is the amount of heat, Btu, transferred in time t, h k is the thermal conductivity, Btu/[h ft2 (oF/ft)] A is the area of heat transfer normal to heat flow, ft2 T is the temperature, oF x is the thickness of the conduction path, ft. (2) Convection h is the heat transfer coefficient, Btu/[h ft2oF]. dx ...

If enough heat is transferred out of the pipe, the pipe contents may thicken or solidify resulting in damage to pipes or pumping equipment. The following sections address fundamental heat transfer concepts used to arrive at a general formula that is used in heat loss calculations.
