OK so I'm sure there is probably already a thread on this, but my search didn't find me what I'm looking for so I decided to post. If its already posted paste me the link. I recently came into three 15 gallon kegs that I'm going to use in a sort of electric-propane hybrid HERMS system on a single tier system with a custom built frame. So basically I'm looking to use propane for my boil, but electric to control my mash temp on the HERMS unit side. My problem is that I don't know where to start when it comes to installing electric elements in my HLT and how to control it. I already have a temperature controller, but its the STC-1000 aquarium controller I used for my mini fridge for fermentation control, and I haven't seen any talk about using one of these to control electric elements. Can I just wire the element to a cannibalised extension cord and plug it into the temperature controller or do I need a relay like I've seen in builds with other controllers? Another issue is that I'm looking at 110v rather than 220v since I don't have access to a 220v plug in my garage (I mean, I could use my gas powered generator that has a 220v output, but that's noisy and excessive, especially if I brew late at night) and my temperature controller is 110v as well. I figure no reason to add a 220v outlet and build another temperature controller if i can just use what I already have and save some money in the process. If I'm trying to heat a decent amount of water (five or ten gallon batch size spare water) would I be struggling with one 1500-2000w 110v element or would it be possible to run two or three 110v elements (1500-200w) in the HLT or am I looking at pulling too many amps? Would there be a way to run multiple elements (either in parallel or series) in order to not overload the temperature controller? Its been a while since I have tinkered with electronics and ran stuff through formulas, so I apologize for any questions that may seem novice. If it won't work, I will just get another propane burner and run that for my HLT, but I would really like the tighter control on my mash temp that I could get with this setup and want to get all the info I can before I start drilling holes in my kegs! Thanks all and again, if this has already been covered (110v with the STC controller) please point me in the right direction. Thanks!
