Thermal energy network
A thermal energy network (TEN) is a type of district heating and cooling system in which a shared water loop exchanges heat with the ground, othen through shallow geothermal boreholes, with connections to multiple buildings which utilize heat pumps for heating, cooling, and potentially Water heating. In the important ANSI/CSA/IGSHPA C448 Design and Installation standard, these systems have been termed district energy systems Unlike conventional district heating systems that distribute steam or high-temperature water from a central plant, thermal energy networks generally circulate water at relatively low or ambient temperatures.
