This research aimed to study power generation from heat loss of gas strove by thermoelectric generator unit. As cooking with a gas stove can cause heat loss between the stove and the cookware, this heat loss from gas stove can be converted into the electricity. For the experiment, the researcher used a gas stove model KB5 installed with thermoelectric generator to convert the heat energy from the gas stove to electricity with thermoelectric plate model TEG1-241-1.4-1.2 connected in a series to the power of 4 modules. Then, experimental conditions of the gas pressure in the gas strove were set at 0.1, 0.2, 0.3, 0.4, 0.5 and 0.6 kg/cm2, respectively while the amount of mixed air was constant during the experiment. The results showed that when the gas pressure was at 0.6 kg/cm2, the temperatures of the hot side and cold side of the thermoelectric generator was equal 250.5 °C and 65.5 °C, respectively. It also generated the highest electric power of 53.3 Watts. The power conversion efficiency was 5.3 % at 38.1 Volts with 1.4 Amperes. In addition, when electric was connected to a thermoelectric generator unit with 12 VDC 7-watt LED bulb, the gas pressure in the gas stove were set at 0.3, 0.4, 0.5 and 0.6 kg/cm2, respectively was affected by the difference between the heating temperature and the cold temperature in the range of 185 °C to 51.1 °C, that could lighten up LED bulb.
