The most common energy sources for single-family buildings are coal, gas and fuel oil. Increasingly, investors are also considering heat pump installations. Each of these sources has different investment and operating costs. The idea of a hybrid source is the cooperation of several energy sources in one building. The aim of the study is to select the best shares of sources from three criteria: minimum investment costs, minimum operating costs for an assumed period of time and minimum sum of investment and operating costs.
