Abstract:
This paper presents the initial research on the possibility of using energy from the sewage. The analysis presented in the paper aims to show how the system of waste water in buildings reject energy, which can be re-used to heat hot water and buildings. Waste water from toilets, washing machines, showers and kitchen has a certain thermal energy which can be used in heating systems with heat pumps. The waste water can be used via heat exchangers to increase the coefficient of efficiency of the heat pump COP. In this way it is possible to achieve substantial savings of energy required for heating. The analysis was conducted for the City of Doboj, Bosnia and Herzegovina.

Key words:
Energy, sewage water, sewage sludge, heat pump.
