Economic Evaluation of Heating Systems for Energy Efficient Houses: A case study of various heating systems of family houses in conditions of central Europe

Popis výsledku v původním jazyce

The case study works with a typical representative of low-energy family house (with its parameters close to the passive standard) on which different types of heating and hot water preparation are discussed. The paper discusses technologies for space heating and hot water preparation as follows: 1) electric direct space heating and boiler for hot water, 2) electric boiler for space heating, 3) heat pump for hot water preparation, 4) air/water heat pump for space heating and hot water preparation, 5) air/water heat pump for floor space heating, 6) condensing gas-fired boiler and floor heating, 7) air/air heat pump + heat pump for hot water preparation, 8) pellet boiler with heat accumulation. The economic evaluation of the options is performed using the basic criteria of economic efficiency, i.e., NPV, IRR, Ts (repayment period (simple)), Tsd (discounted time). The article analyses the advantages and disadvantages of individual technologies and their combinations both in economic terms and in terms of energy efficiency and comfort of use. At the same time, the paper presents estimates of changes in the consumption of electricity and other forms of energy for heating and hot water production from the point of view of the expected rate of construction of new and reconstruction of existing family houses.
