Cold in summer and warm in winter? The now-popular renewable energy, sewage heat.

Abundant unused energy exists within the city! It demonstrates energy-saving effects and CO2 reduction effects.

Wastewater discharged from homes and factories is transported through sewer pipes to treatment facilities, where it is treated and then released into the sea or rivers. Since these sewer pipes are buried underground, they are less affected by external temperatures, resulting in wastewater that is "cold in summer and warm in winter." The thermal energy from the temperature difference between wastewater and outside air is referred to as "wastewater heat," which can be utilized as a heat source for heating, hot water supply, and snow melting, thereby achieving energy-saving effects and reducing CO2 emissions. Although it is stable and abundant, there are still few examples of its implementation, and its promotion is expected to increase with the advancement of decarbonization as a renewable energy source. *For more details, please refer to the PDF materials or feel free to contact us.*
