yup. That would probably do it. You might have to tweak the PWM circuit a little to get a more reasonable frequency on it if it's unsuitable as-is, but that would be as simple as probably just swapping out one of the capacitors on the board.

You will also want a switch in there so that you can manually shut the element off, but you should be able to get such a switch at the hardware store for (guessing) $5.

I need to do this for my heat stick. The full 2k watts splashes wort like crazy while boiling 7.5 gallons. Thanks for the info Walker.

this one has heatsinks and a status LED on it.
just poking around ebay now...

Really? 2kW and a violent 7.5 gallon boil? That's pretty impressive, actually.

I have a wide/shallow kettle, so it tends to splash a lot since all of the heat is coming from a concentrated area. Using the stove burner on hi can barely maintain a boil. I need something in between. It's crazy that a 3500 watt stove burner is so much less efficient than a 2000 watt submerged element.

Do either of you guys recommend a 25A ssr and 2KW heater. I am getting interested enough to order some parts. I already have the 10 gallon brew pot and frankly it is a bit much for my stove.

I like the idea of continous (albeit manual) solid state control.

So Walker, if I were to buy that PWM with the status LED on it, I could use it to control a 5500w element?

You can control whatever you want with it. It just genrates a low voltage DC signal that you connect to an SSR. If the SSR is able to handle a 5500W element, you are good to go.

Do you know what size SSR would be best to use? I'm looking at http://www.auberins.com

Crap, maybe I should just stick with propane. The rabbit hole just keeps getting deeper.
