Abstract
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.
Highlights
As presented in the literature [1, 2], civilization progress in the second half of XX century caused a rapid increase in the energy needs of the world
On the basis of the comparative analysis of the heating system, taking into account technical, economic and environmental criteria, it appears that for a single–family building being analyzed, a more advantageous solution is the use of a system based on a condensing gas boiler
The economic analysis showed that the total cost for a gas boiler based heating system is 11% lower compared to a compressor heat pump
Summary
As presented in the literature [1, 2], civilization progress in the second half of XX century caused a rapid increase in the energy needs of the world. Taking into account the dependence of the modern world on non–renewable energy resources and their strategic importance in economic development, the efficiency of energy use and the search for alternative sources should be the subject of special attention. Another problem of modern energy is described in publications [3]. Heating accounts for 72% of all energy needs of the building With this in mind, saving energy and its rationalization as well as reducing emissions of environmental pollutants should manifest in particular in activities related to improving energy efficiency in buildings. The implementation of new technologies in construction and installation technology, reducing energy consumption, promoting buildings with low energy consumption and increasing the acquisition of energy from renewable sources should be the basis for achieving the assumed goals
