It all started with a 10gallon Rubbermail cooler There are many places both locally and online to find one. Home Depot often carries them... |

Drill and burrow from the side of the cooler for your power cord. |

Connect power leads with crimp connectors and soldier the ground wire to the ring. |

Seal a pvc cap in place with silicone. |

With sight-glass and thermometer added here is the finished HLT. |

5 gallons of water were brought to 170F in just over 30 minutes. We are at 2,500ft, my thermometer is a few degrees off and the thermometer probe is located near the lower edge of the tank. Those three factors, I think, explain why the water was boiling at the end of the element yet the temperature was reading less than 190F. |

Kremer from the Brewboard sent these great pictures of his grounding ring(s). Thanks, Kremer!

Brew Strong - OUT!
1) Are there any heat issues around the fitting with either the plastic cooler body or the insulation around the power wires?
2) Do you run this on a GFI breaker?
1) my batches need water no hotter than 170F and no negative effects to the cooler so far.
2) YES GFCI all the way. The entire wortomatic control panel plugs into one. BTW, with the heating element I use I had a new 20 amp service installed just for brewing (and insane Christmas lights).
I want something that is removable so I can calibrate the themometer. Thanks!
Vince, that is the gasket that comes with it.
There is another kind of mount available that I will use when I update this HLT that has a screw-in plate:
Cheers,
Push E.
If you use pumps, there is no need to modify or drill the cooler in anyway, just replace the spigot with a ball valve.

@brant Not since I remade it with the plate and gasket.
@vince I guess so! :)
I've read reports from people building heatsticks, that the silicone fails on them after about a year or 2. Have you had similar problems?
I only ever get a leak (and it's a very slow, minor drip) when I fill it up and let it sit overnight. If I fill it and start brewing it is great. I've done dozens of batches now and am very comfortable with this setup.
Pumping the mash through a coil immersed in the HLT has proved a great way to raise mash temps.
So far, no rusting.

Electricity is just as safe as any other method of heating up water (how many of us have electric water heaters in our houses?), but it is also a ton safer to use inside.
Personally, I'd love to have the money to buy a bunch of stainless steel kegs... ain't gonna happen until I'm out of school (Paramedicine, in case you were wondering).
I think Push Eject wrote up a really good, straight-forward "how I did it" tutorial and should be commended for sharing the information, as opposed to being lectured on the faults involved.
Cheers!
"It's not really a straight answer because officially we do not recommend putting 170 degree liquids into our chests. There are some potential issues with the foam and if you get close to boiling you are nearing the temperature that will start to (not melt) soften the polypropylene liner. Officially the cooler was not designed to hold boiling liquids. But if they happen to find there way into your cooler it won't poison you! People have done it without issue but I really don't like to see it being done!"
So, ideally, nothing will poison you, but Igloo doesn't recommend doing it. There you go.
To be clear, I do not boil water in the HLT, but it does approach 175F. You know, now that I think about it, don't most of us mash in coolers? If you do a mash out you probably have the issue, right?
Nonetheless I am considering building a new one like Kai Wallner's at:

I did not use a Blichmann kettle, rather, found a 20 gal SS kettle with lid for $150 shipped.
BTW - taking a SS coil as shipped and reshaping into a tighter coil to function as the HERMs coil (per Kal's pictures) is not a trivial task! Search his forum for HLT coil and you will see some of the ways others were or were not successful.
