Combined heat and power (CHP) and electricity generation from photovoltaic modules and wind turbines are essential elements in the German government's energy transition concept. A doubling of the CHP electricity share to 25 percent by 2020 is planned. The economic operation of micro and mini CHP systems requires individual and project-specific planning and sizing. This technical book provides the essential facts: it presents the current state of technology and highlights emerging trends and potentials. The focus is on the planning and integration of CHP systems into the heating and electricity supply of single-family and multi-family homes. Content includes: CHP technologies, application areas, sales markets and potentials, planning and sizing, hydraulic, electrical, and control integration into building technology.
