Abstract

Efforts to apply science and technology are very important, namely improving the welfare of the wide community. The water dispenser is a household electronic item that many people like because it is practical to use. The water dispenser has a main part, namely a heating tube which functions as a heater and a container for storing hot water. This heating tube has an electric heating element of around 400 - 500 W. In the water dispenser, the heating tube is open to the air, resulting in heat loss. Because the source of heating energy comes from electrical energy, saving efforts need to be made. In this research, modification efforts were made, namely by covering the surface of the heating tube using a heat insulating material, namely glass wool. The next step is testing the dispenser before and after modification. The test includes observing the duration of time required from normal water temperature to hot water temperature and from the heater not turning on until it turns on again. Analysis of the test results data is then carried out to obtain the performance of the water dispenser. Based on the results of the analysis, electricity consumption for one water dispenser unit after modification was 11.7 kWh/month and before modification 36.8 kWh/month. Thus, modifying the water dispenser by covering the surface of the heating tube with glass wool can reduce electricity consumption by around 25 kWh/month.
