The most commonly used source of energy for single-family dwellings are coal, gas and oil. Increasingly, investors are considering a heat pump installations. Each of these sources has different investment and operational costs. The idea of a hybrid source relies on the cooperation of several sources of energy in one building. The aim of the study is selection of the best hybrid sources from the three criteria: minimum investment cost, minimum operating costs for a predetermined period of time and minimum of total costs of investment and operation. Variable parameter is the size of the building defined as the length. The building is has the shape of a rectangular prism with a square base. It calculated heat demand of the building and then selected hybrid heat source. Heat demand is calculated using the simplified method of annual balance sheet and heat source selection is to calculate the cost for 286 shares of selected combinations of sources and selecting minimal cost. Conclusions has been derived about investment and operating costs of hybrid sources with different proportions of ingredients.
