System Research in Energy| Summary: | There are, almost 50 % of buildings in Finland, mainly in cities, are connected to district heating systems.However, the role of autonomous heat sources is growing, in particular heat pumps and solar thermal collectors, which are used as an effective alternative to traditional heating technologies. The paper presents a comprehensive technical and economic analysis of the feasibility of using alternative heating systems (heat pumps and solar collectors) in Finnish conditions. The paper analyzes the effectiveness of using heat pumps and solar collectors in Finnish conditions, taking into account their efficiency and cost. It is shown that the climatic features of the region are decisive when choosing equipment, in particular, a long heating season and low temperatures and low solar activity in winter. The analysis shows that European equipment loses in economic indicators to Chinese counterparts, i.e. for projects with a limited budget or in conditions of an unstable economic situation, Chinese heat pumps may be a better choice. The efficiency of solar collectors in the Finnish climate, despite their environmental attractiveness, is limited due to the insufficient number of sunny days, especially in winter. However, their use may be advisable in combination with other energy sources, such as heat pumps. This approach allows you to optimize energy consumption and reduce the load on the main heating system in the summer. Vacuum collectors demonstrate better performance in the cold season compared to flat ones, which makes them a more acceptable option for Finland. This approach is especially relevant for buildings that are not connected to centralized heating systems, as well as for newly constructed facilities where modern energy-efficient solutions can be implemented “from scratch”. The aim of the article is to conduct a feasibility study of the prospects of heat pumps and solar collectors, taking into account the cost of money in Finnish conditions. At the same time, a comparative analysis of the indicators of the use of equipment manufactured in Europe and China, as having different costs, was carried out. |
