Abstract
A heat exchanger system extracts heat from sewer waste water. Preferably, a first surface is narrow band in an interior surface of a pipe, and the band is preferably oriented transverse to a direction of fluid flow. In the case of a horizontal pipe, the band may be a partial band, and may be limited substantially to a wetted portion of the pipe in order to reduce the size of the band.
