Towards More Sustainable Kitchens: Experimental Assessment of Energy Efficiency and Heat Losses in Turkish-Type Electric Tea Makers

Improving the energy efficiency of household appliances can reduce electricity consumption and support more sustainable kitchens. This study experimentally evaluates the energy performance and heat losses of Turkish-type electric tea makers. Three models with nominal powers of 1600–2000 W were tested using 74 valid observations. The average useful energy transferred to water was similar across the models (174–176 Wh), while electricity consumption was 228.57, 244.70, and 225.92 Wh for M1, M2, and M3, respectively. Their corresponding average energy efficiencies were 76.18%, 71.05%, and 77.73%. Model M2 had the shortest initial boiling time (200.16 s) but the highest electricity consumption. This shows that higher power does not necessarily improve cycle-level energy efficiency. The heat-loss analysis identified differences in surface and evaporation losses among the models. The findings provide experimental evidence to support energy-efficient appliance design and more sustainable household energy use.
