The element failed because it ran dry. Low density design or stainless sheath would not have prevented this. Basically the element sheath melts, any moisture that is introduced to the magnesium oxide powder within the element will cause an electrical short to the sheath and will also expand...

If you have a multimeter measure the element resistance. It should be around 7.2 ohms. This would confirm that it is indeed 2000w at 120v

You can use what is termed as a PWM control ( basically a rotary dial device ) that controls the input signal to an SCR, effectively controlling the boil. They are very cheap to build if you are able to solder electronics. Jim

The formula is 220v squared divided by 380v squared or 33.5 percent of 9000w you will get 3016 watts out of the element Jim

I just use a piece of elastic ( out of my wife's sewing basket ) wrapped around my fermenting bucket and stick the probe underneath. Just make sure you are under the liquid level

Not sure how to calculate CFM required but for safety reasons it is very important that you make sure there is makeup air for ventilation when exhasting this much air.. Ventilation without can create a negative pressure causing backdrafts of carbon monoxide from furnaces etc, effectively...

Hi Here is my cheap & dirty stir plate version. I had the 5" computer fan, the hard drive magnets and the 12v power supply. Used 2 1/2 bolts with nuts for legs, fan already had pre-drilled holes in each corner. Glued a piece of plastic on one side in order to mount the potentiometer. Didn't...

Hi I have been in the electric heating business over 30 years and have a few concerns. First, simply wiring up an element of some sort may or may not heat the space depending on enclosure design.it simply depends on heat loss of the enclosure as compared to the wattage of the element. A...

The STC1000 uses an NTC ( or thermistor ) type sensor, not a thermocouple. This is why sensor leads can be extended without special wire.

Why not just use an old yeast bottle ( white labs ) just drill a hole in cap and tape to side of keezer. Mine works fine. Jim
