“…The production of energy-efficient dishwashers increases the idea that purchasing a less energy-consuming dishwasher can also contribute to preference in the competitive environment on the market. As discussed in Wikler et al (1993) than just economics go into a customer's decision to purchase products such as energy efficiency. European Union (EU) policies contribute the improvement of energy efficiency and other environmental performance-related aspects of products in the internal market (Alborzi et al, 2017).…”

Heat recovery and energy savings from the graywater of household appliances, such as dishwashers and washing machines, can encourage people to avoid the unhealthily long hours of hand dishwashing. In this experimental study, the size of energy saving that could be obtained from a domestic dishwasher with a wire on a tube heat exchanger attached was investigated. The study results validated that heat recovery from graywater is possible and equivalent to annual electricity savings of 53.48 kWh. The efficiency of the dishwasher can be increased to approximately 16% by saving energy, and the economic value of efficiency increase can be $5.88 per year. With all fittings, pipes, and fixing equipment, the heat exchanger cost was also calculated to be $35 per machine, and the payback period is 5.94 years per machine. The payback period can be shortened by achieving lower production costs with mass production. Furthermore, the possible reduction of CO2 emission by saving electrical energy was estimated to be 26.74 kg. In Turkey, nearly 8 million units of dishwashers are in domestic use, the size of the annual energy saving can be 427.84 GWh, and the economic value is $47.04 M. By energy saving, approximately 213.92 kt/year less CO2 released. Practitioner points Graywater heat recovery with a wire on a tube heat exchanger was studied experimentally. The energy consumption and processing time of a household dishwasher is shortened by graywater heat recovery. With the decrease in energy consumption, a reduction was achieved in the CO2 emission released during the energy generation.

“…(1990) in dicates that the maximum technical potential electric energy savings are distributed throughout the residential, commercial, industrial, and transportation sectors. The main results were summarized and discussed in several other articles (Lamarre et al 1990, Gellings and Yau 1991, Wikler et al 1993). The energy-saving technolo gies are classified as electricity-saving technologies^ and electrification technologies^.…”

The funding support, information input, and professional suggestions for this project from the Midwest Power Systems, Mr. Tom Sweeny and other staff, are very appreciated. My mother Mrs. Yu-Mei Liao, elder sister Mrs. Kuei-Chong Hsu, and brotherin-law Mr. Ching-Lin Chen are lovely family members. Thanks for their tolerance, love, and help. I am grateful to my mother-in-law, Mrs. Hsiu-Hsiang Peng. Without her uncon ditional support and encouragement, it is impossible for me to continue the advanced graduate studies. Special thanks are due to her. To my wife, Yiming (Debby), I wish to thank for her understanding, patience, and ebullient support over the years. Her continued love, encouragement, and confi XV dence in me have co-contributed to the possibility of this dissertation. Finally, I want to mention our son Darwin, an Iowa boy, who absolutely enriched my study career.
