This paper discusses the use of modern and effective heating systems, using fossil fuels and renewable energy sources on the example of a comparative analysis of a gas boiler and heat pump for a single-family building. The aim of the work was to conduct a comparative analysis of heating systems in terms of energy, economy and ecology. The concepts of heating systems based on a gas boiler and a heat pump are proposed. An economic analysis based on the LCC and ecological method was carried out, related to the equivalent emission, in order to compare the degree of environmental nuisance of the proposed heat sources. For the building in question, a more advantageous solution was the use of a system based on a condensing gas boiler. The economic analysis shows that in the assumed life cycle (20 years), the total cost for a heating system based on a gas boiler is lower than in the case of a heat pump by 11%. Also, the initial costs in this variant are lower by nearly half compared to the heat pump system. Environmental analyzes have shown lower annual emissions of pollutants and a 6-fold lower equivalent emission for a gas-fired heating system.
