Sažetak

The article discusses utilization of heat from waste water in sewage. During the year, temperature of water in sewage ranges between 10 °C and 20 °C and the heat from sewage could be used for heating, cooling and hot water preparation in building. The heat is extracted through a transfer surface area of the heat exchanger into the heat pump, which is able to utilize the low–potential energy. Different design and types of the heat exchangers in sewage are dealt with: heat exchangers embedded in sewage pipe, heat exchanger integrated in concrete wall of a sewage pipe, sewer pipe with special double jacket as well as double pipe heat exchanger. Technical data about usage of the heat exchangers is also specified.
