Step 3: Remove the plug.

This is the most difficult step. Go slow. Take your time. Be careful.

Wrap the tube in the towel. This will protect your hand if something goes wrong and you shatter the glass.

Using the pliers, grab the plug. Put one end in the hole and the other end on the edge of the plug. Slowly work the plug out. Try not to tear the rubber, or pull on the cord.

Once you get the plug most of the way out, slow down and pay attention. The heating pad will come out and you will need to get it back in. Mine had a foam insert that was wrapped around a plastic tube.
<p>30w is getting you to sous vide temps? I was planning on needing 100w minimum, possibly 200w to cook ~10lbs of chicken in a 5gal cooler </p>
The answer is &quot;Eventually&quot;. In a decently insulated vessel 30w can shift the temperature surprisingly fast. That said, with this setup I usually heat the water by other means before adding it to the cooler. You can fill it with cold water and then bring it up to 140-150F easily with a pot of boiling water from the stove. I have also just filled it with 110F water from the hot water in the sink and let the heater bring it up over the course of an hour or so.<br><br>If you want to heat the water quickly, you need a much bigger heater. I have cooked 20+lbs of meat in a large cooler with nothing but this heater and it was off more than it was on. It puts out plenty of energy really. If your vessel is not well insulated you might be losing heat faster than this would replace it but you would have to have really bad insulation and put it in a cold place. Even just wrapping some towels around a pot should work fine.
