“…Analyses published in recent years on the economic viability of using HPs [129,139] indicated that it is possible to develop an efficient energy system based on wastewater energy and solar energy. Li and Wang [169] showed that the use of wastewater HPs in buildings deserves popularization due to the relatively low investment outlays and dynamic annual computation cost of the HP compared to other heating and cooling technologies. Hirvonen et al [170] have also shown that the use of wastewater as an additional source of energy for a ground source heat pump can improve system sustainability and reduce its life cycle costs by up to 20%.…”

The potential for recovering heat from wastewater exists at various stages, including generation, transport, and treatment. As a result, various technologies for thermal energy recovery from wastewater are now successfully employed in many countries. In order to synthetically present the current state of knowledge on heat recovery from wastewater, a bibliometric analysis of previously published studies indexed in the Web of Science database was performed. The review was further extended with strategic SWOT and SOAR analyses to identify internal and external factors determining the competitive advantage and weaknesses related to the use of wastewater heat exchangers and heat pumps. These analyses indicated the need for further research on the possibilities of heat recovery from wastewater as the use of this technology, both at the building level and on a larger scale, contributes to the implementation of sustainable development goals, especially in terms of improving energy efficiency and reducing CO2 emissions. Particular emphasis should be placed on research into the use of warm wastewater together with other, better known and accepted, renewable energy sources. It is also important to continuously educate the public and promote heat recovery technologies at various levels, as well as to increase the involvement of legislators and other stakeholders.
