Selection of Heating System Based on Acquisition and Operating Costs for Family Houses

Abstract

The aim of this study is to evaluate mutual dependences and significance of the input factors of a heating system for a family house. The input factors which are being most commonly considered are operating costs, acquisition prices on financial return rate, life span of these systems or requirements for maintenance and control. This research is focused on the analysis of three different heating systems in the common detached house; electric heating foils, heat pump and gas boiler. The building itself is evaluated in three variants; with and without a ventilation unit and with adjusted structure composition. To analyse the parameters mentioned above the Promethee method (multicriterial analysis) has been used.

Evaluation of suitability of selected hardwood in civil engineering

“…8.Criteria group I -price is considered slightly more significant than criterion II -physical properties. PROMETHEE methods compare all alternatives Aj and Ak, by determining preferential relation π (Aj,Ak) The calculation procedure is described in details in the literature [3], [15], [22] and [25]. PROMETHEE method contains 6 basic types of preferential functions.…”
