The Masters´ thesis deals with the innovation of solid biofuels, small-scale solid biofuel boilers and conversion to smart boilers by significantly reducing fuel consumption and pollution emissions. The Europe 2020 Strategy Paper calls for the building of a bioeconomy, i.e. biomass economy - organic products creating key elements of the smart and environmentally sustainable growth agenda in the Europe. In comparison with other natural resources, renewable carriers - energy raw materials - in Slovakia, biomass after solar radiation and geothermal medium represents an energy carrier with the third most useful potential. Targeted cultivation of energy crops and trees in accordance with environmental standards allows for the efficient use of less productive agricultural land. The use of biomass in the quality class “fuel biomass” from primary agricultural production, forest mining and energy crops represents a high potential for the development of regional and local economies. We compare heating methods in terms of energy and economic efficiency as well as environmental effects. The thesis analyses the causes of the increase in the cost of alternative fuels within individual heat sources. The comparison is made using specific costs and recalculated to total annual costs. Technologies are clearly described in the thesis. The thesis deals with the choice of heat source - a progressive biofuel boiler, which would fit into its newly created type of biomass-based economy in both Slovakia and the EU.
