No + / - on heating element
 
So in building my eHLT I just noticed that there are no positive or negative markers on the heating element... any suggestions?

Thats because it dosent matter.
Cheers

Ok yeah i wasn't sure and didn't want to go hooking stuff up w/o any direction...

It's just a big resistor, you'll be fine.

Jaybird 10-03-2008 11:24 PM

Not that it matters but are you using 110 VAC or 220 ? and what size elements are you using? I just love my electric HLT. What are you going to use to control the temps?
good luck w/ the build

110 VAC, since i don't have a 220 in my apartment, element size, i think it's like 12 in long and it's a 4500 watt. I'm controlling it w/ a love thermostat...

I still need to finalize it putting it together, i'm hoping to have it up and running for testing by next week. What do you use to stir it for consistent temps?

A stainless spoon... But I am in the process of building a stir bar.
I would be interested to see a 4500 watt element run @ 120VAC thats somewhere around 37 amps I dont have a calculator handy just an educated guess on amps. Are you doing 5 or 10 gallon batches?

If you're planning on running a 4500W element designed for a 220VAC circuit, you'll only get 1125W at 10A when you plug it into a 110VAC circuit.

If it's a 4500W element designed for 110VAC, you'll draw 41A, quickly tripping any household breaker.

come to think of it they dont even make a 4500watt 120VAC element...Do they?? (who ever "THEY" are)

I have a 120VAC 1500W element in my HLT/HERMS and it works great, I use a JC 419 to control the temps and a motorized stirrer.
