This technology utilizes the thermal energy of sewage, whose temperature is more stable than the outside air, for air conditioning, hot water supply, floor heating, and snow melting.

Use of sewage heat energy for air conditioning, hot water supply, snow melting, etc.
This technology realizes the effective use of unused energy at the same time as the rehabilitation of sewage pipes in an aging era when sewer pipes that were installed during the period of high economic growth are due for replacement.

①Small and medium calibers can also be heat-collected.
② Stable heat collection is possible.
③ Simultaneous construction with pipeline rehabilitation can reduce construction costs.
④It is also possible to perforate the mounting pipe.
⑤ There is no odor.
⑥ Thermal energy can be used permanently.
⑦ It can also be applied to air conditioning, snow melting, etc.
