Sustainable Economic Solution using Azerbaijan Data to Prevent the Wasted Fresh Water in the Start of Shower Time and Reduce the CO2 Emission using Low Cost In-Line Electrical Water Heater
This paper discusses domestic problem of waiting the water for the shower use till it reaches satisfactory warm temperature, which result a lot of wastage in fresh water. The outcome from research survey shows that there is no satisfactory solution till now as all solutions were either expensive or with no effective results. Local small inline electric heater equipped with controller is proposed in this paper to be installed just before the showerhead to measure the water temperature and flow before the showerhead, as control input-variables, and decide the operating voltage of the heater, as control output-variable. Techno-economic study is carried out to determine the “Direct Benefits” and “Indirect Benefits” that can be achieved if such system is implemented in wide range. Azerbaijan data is taken as an example to calculate the economic benefits. The results show important benefits not only for economy but also for climate and the reduction of CO2 gas emission. Different economic indices are provided to be an easy reference for decision makers and project managers.
