Even if there was a cycle limitation, how often are you likely to hit the e-stop? I've used mine exactly once, and that was during testing.

Thanks. It's the tank from a high voltage capacitor switch. I was going to use a paint can until I saw this in the scrap heap at work. It's a lot more sturdy.

I just finished building my heat exchanger and thought I'd share some photos. Did a test run with 6 gallons of water and was able to raise the temp a little over 2 degrees per minute. Here is the inside view. I was able to stuff 25' of 1/2" ID tube in there. The tank holds about a...

I use a timer to start my HLT. The ability to wake up and immediately mash in saves a ton of time. To make it as safe as possible, I use a float switch to shut the element off if the water level gets close to the element to prevent dry firing. I also use an alarm contact on my PID to shut the...

I think the terminals on the GFCI outlet are bussed together, so you can't switch them separately. Just make a box with two switched regular outlets and a cord and plug it into the GFCI outlet.

There is no problem with that, provided your feeder is rated for at least 50A. The GFCI will trip on ground fault current on the order of milliamps.

In that case I'd start with the 1500W @ 120V element and switch to the 5500W @ 240V element if you find yourself blowing fuses. Your pump probably only draws about an amp so you might be alright.

Your schematic looks good, except I'd use a 20 amp circuit if available as you'll be pushing it pretty close to 15 amps with your element and pump running at the same time.

Not sure about Home Depot, but Lowes carries 6/4 SER cable, which would be good for 50 amps. Personally, I'd avoid the big box stores and go to your local electrical wholesaler. They'll be cheaper and should be able to cut you off a piece of the exact length you need. I got 40' for about...

The only downside to aluminum I've heard of is that it expands and contracts more than copper, so terminations can supposedly come loose easier that with copper. I haven't found this to be the case with the aluminum feeder I ran for my brewery yet, but I plan on torquing down the connections...

I put the probe on the side of the carboy away from the fermwrap. Works great. I would think if you put it in between the carboy and the fermwrap you would get false high readings and the beer temp would be too low. As far as insulation, I use a big piece of bubble wrap held in place with...

That has been my experience with WLP550. I fermented a beer @ 64 and it was crazy phenolic, almost undrinkable. It did mellow out after a few months but was never that good. On my second attempt with that yeast, I pitched at 65, held at 68 for a few days, then ramped up one degree a day up to...
