Next I tested Electric Steam Boiler #3
with the 1/4 HP AJ Weed steam engine.
This rig was doing great until I walked away from it for too long. I thought there was plenty of water but I think the heating element got exposed and fizzled out. I learned afterward that the element was mounted higher up than I would have imagined. I already went to HD to pick up a new heater element. Hopefully it will work. It is a 240 volt 5500 watt immersion heater which should be 1375 watts on 120 volts, all for the princely sum of $20.
Here is a video of it before the heater failed.
