In this article a technical and economic analysis was performed concerning the use of different types of boilers for combustion of biomass such as straw boiler, boiler for burning wood chips and boiler with a burner for oats. Technical analysis of the boiler covered: power selection, estimation of the seasonal demand for final energy for examplary residential building. Calculated final energy consumption helped to determine the area of cereal crops whose straw and oats will be used as well as the surface of Miscanthus and rose multiflorum. Economic analysis based on life cycle cost method allowed to choose the heat source, which will be the most efficient in economic terms in assumed period of operation. The use of the boiler for combustion of straw will be the best solution. It is characterized by the lowest costs in the case of burning straw bales as well as the use of Miscanthus. The use of boiler burning wood chips combustion generates a cost comparable to Miscanthus. The use of boiler combustion grain oats, which would be specially manufactured for use for energy purposes is not economically justified. Heating costs in this case are 3.5 times higher in comparison with straw burning boiler and double in the case of using the combustion boiler chips. Assuming energy plantations depending on the species, there may be two types of heat source, i.e. boiler burning bales of Miscanthus or automatic set to burn wood chips of rose multiflorum.
