That was a mistake, the second link should be this crappy heating element: <a href="http:&#x2F;&#x2F;www.amazon.com&#x2F;gp&#x2F;product&#x2F;B000VK0DRY" rel="nofollow">http:&#x2F;&#x2F;www.amazon.com&#x2F;gp&#x2F;product&#x2F;B000VK0DRY</a><p>The water pump has been fine so far after maybe 10 hours of being immersed over a few weeks, I figure if it gives up I&#x27;ll get another one.<p>I put a pot on top of a hot plate.  The hot plate is turned on but the Willhi unit turns the power on and off.  At first it overheats the water by about 10 degrees, so give it time to heat up before immersing the food, but after cooling down it oscillates around 1 degree Fahrenheit.<p>Before the hot plate, I had that coffee element which I taped to the side of the pot.  The problem with that previous heater was that despite saying &quot;immersion&quot;, you can&#x27;t submerse the cable without electrifying the water.  The thing got banned in Canada.  Don&#x27;t buy one.
