I decided, on a whim, to build a 2000W heatstick this weekend based on THIS design. I batch sparge and figured a heatstick not only would help me save a little propane when heating my strike water, but may make the option of a mash-out easier.
All in all, the instructions from the aforementioned website were simple and the overall cost was under $50. Here are a couple things that might help folks planning to do the same thing:
1. Purchase the 12 gauge power cable in bulk. I found everything I needed at Home Depot, including 12 ft of bulk 12 gauge power cable... which wasn't next to the extension cords. With the plug, I spent about $16 for the power cord, compared to $30 for the cheapest 12 gauge extension cord.
2. For the life of me, I couldn't find the 1 1/2" to 1 1/4" chrome slip reducer referred to in the instructions (from the website above). When I asked a HD employee, he looked at me funny and pointed me in the direction of PVC slip reducers. I actually went home empty-handed the first day I looked for it... then realized what the instructions are referring to is actually a 1 1/2" to 1 1/4" "slip joint nut and washer" set (click HERE to see it). These can be found in the plumbing section near the bathroom stuff.
Other than that, the instructions were great! I'll be sure to post once I finally use the heatstick for a brew day.
