What Does Heat Exchanger Surface Mean?

A heat exchanger surface is a type of pipe liner that is used to extract thermal energy from wastewater in sewer pipes. As wastewater flows over the heat exchanger surface, heat energy is absorbed through the liner material to be extracted via a heat pump. The extracted heat can be used to heat houses and buildings during winter.

Heat Exchanger Surfaces are also known as Heat Exchanger Mats.

Trenchlesspedia Explains Heat Exchanger Surface

Heat exchanger surfaces provide an economical alternative to conventional electric heating. Wastewater is a significant source of thermal energy; its temperature generally varies between 10 to 20oC.

Heat exchanger surfaces allow this generally ignored energy to be harnessed for building heating applications.

Heat Exchanger liners are installed on the inside of pipes and kept in place with an outer liner. Unlike cured-in-place pipe (CIPP) liners, heat exchanger liners are non-structural, i.e., they cannot be used to rehabilitate damaged pipes on their own. However, they may be installed together with structural liners should rehabilitation be needed.
