I've been putting together a RIMS and all electric brewing system. Finally got to try it out on Saturday. Easiest brew day I ever had. Made 10 gallons of Helles lager. What a sweet system.
Then came Sunday. The brew club was doing a 50 gallon batch of Hefeweizen and wanted to try it. We hooked it up, I explained how it worked and I went and did some other beer chores. Then someone yelled "I smell ozone". We looked at the temp, it was 148. We looked at the wort returning to the mash tun. It had smoke coming out of the hose. I noticed the RIMS (it's made of PVC) was laying on it's side. I told the boys to keep the output up to get rid of air bubbles. I moved it and burned my hands it was so hot. It then started to melt!!!
Well needless to say we had to dump 50 gallons of beer and about 100 lbs of grain. We started over and brewed the beer until 6:30 PM (we started at 7:30 AM).
Oh well, looks like I can now make one out of stainless steel...
