above the boiler. After the boiler is fired up, the water rises naturally into the generator, which is directly connected to a small centrifugal pump, such as an El-Sid from Ivan Labs. In 2 to 5 minutes, enough water has risen to the thermoelectric generator to exceed the starting voltage of the pump. As it starts pumping, more hot water reaches the generator and the voltage rises. Suddenly, there is vigorous pumping in the system and the heat spreads quickly to the radiators. A small, 3.5 watt...
