Heat distribution Sample Clauses

Heat distribution. District heat is transmitted from production plants to clients as hot water in a closed network consisting of two pipes (flow and return pipes). District heating pipes are laid in the ground, usually at a depth of 0.5 to 1 metre. The pipes have effective thermal insulation. On an average, heat losses in the distribution network account for less than 10 per cent of the energy transmitted in the pipes. Pump energy generally is in the order of x% of the heat transported. The water circulating in the flow pipes releases its heat to clients via heat exchangers. The return pipe conveys the water back to the production plant for reheating. The temperature of return water from clients to the production plants ranges in best cases between 25 and 50 °C. The district heating water in general does not circulate in the space heating networks of buildings, but also direct connection variants to consumer equipment exist.
