110v Recirculating eBIAB 2.5 gallon batches

[Wagon_6]

Two more questions come to mind.

1. Did anyone use a fuse for the pump outlet? Seems like not a bad idea, I'm just not sure what fuse to get.

2. Is this the correct resistor?

Thanks,
Ty

1. I only used the fuses listed on the diagram.
2. Yup

While we are on the topic of fuses, I had a couple more questions about this. I have always seen temp controllers wired like boxbrewer's setup - with a fuse on the heating element, and the EMO cutting power. Unless I am missing something, it looks like the EMO in pj's version is designed to trip the GFCI. Is this correct? Is this a recommend way of doing it in wet conditions or something?

Thanks!

Yes, the EPO in P-J's designs will trip the GFCI. If you are using a subpanel with the GFCI there, when it trips there will be no power in the box at all. If you use a switch and relay to cut the mains power, there is still power to the box.

Some have questioned tripping the GFCI vs simply cutting the power with a relay and the debate at times can get heated.

I personally prefer to cut the power to the entire control panel at the subpanel GFCI.

Yeah, I got some advice from an electrician friend of mine that builds control boxes for a living. He fused the element, pump and PID and then the E Stop was basically the "main power".

 

[inhousebrew]

Yes mine is wired from the element to a male plug end and its held together by a rubber plumbing clamp. In this thread I have detailed the method I used, and warned that there's better ways to do it and mine probably isn't ideal. I will change mine...one day........maybe.

Despite there being a "better way" I am currently in the market for the cheap and workable way because it is after the holidays, I've already spent a crap ton of money getting to where I am and I'm going back to school next week. I've got the control panel worked out, the pump working, the holes in the kettle are drilled and now this is my final step. I can fix it up later if need be....one day....maybe.

One thing I haven't though about is grounding the element and kettle. Wondering what you did under that plumbing clamp?

Got the first brew session in. Temps hold steady and it can move to mashout or boil expediently with 3 gallon batches. I managed 79% brew house efficiency on a 1.049 Citra Blonde ale. I think a 90 min boil would put my kit into the low 80's.

Jammin - are you using the 24 quart Bayou Classic pot?

It's only the 20qt SS. Plenty of room though!

 

[kzimmer0817]

Well I got everything completed and first brew done!
<snip>
After a 10 min mashout at 170 it took 20 mins to get to a hard rolling boil. I left the PID at 100% manual mode and liked the boil strength for the 3.5 gallons. I boiled off .75 gallon an hour like in my water test last night. I think the 10" diameter pot is keeping the boil off rate low.

Can't wait to brew again!

jrb03,

I've enjoyed reading your thread. I think I'm going to direct my e-BIAB build to brew small batches. I can still use the propane to brew the 5-gallon batches.

Question: do I read correctly that you are doing this with a single 1650 watt element?

Thanks,
Keith

That is correct. I had thought about upgrading to 2000 watt but haven't seen a need, the 1650 is working great.

I'm heating some water now, finally, and in auto tune it has overshot the temp by like 20 degrees and keeps rising. Is this how everybody else's has been? Does it eventually come back down?

It's been a while but yes I think your fine. The auto tune is trying to figure out who it is and how much power it has let it do its thing.

Make sure its in auto mode. If you try to autotune in manual mode it just keeps going up

jrb03,

Thank you so much for your continued posting and updates in this thread. I'm so very happy (glad) that I could help you in your adventure. The best part of it all? You have been an immense help to this community.

You make me feel so very honored.

A toast to you. In HONOR.

Thank you..!!

P-J Thanks again for your continuous help with the thread!

I am in the process of making my 2.5 gal eBIAB system similar to the one in this thread with just a few minor changes being A. 2000W element (as opposed to 1650W) and B. March pump (instead of 12V pump). With that said I am worried about Amp rating. I recently just had a 20A GFCI outlet installed that is on a 20A breaker by itself (dedicated brewing breaker) and wired using 12-3 romex. I would like to run everything off of the single outlet but I am a bit concerned about the amp rating and continuous load rules of NEC. My anticipated brew day time and current draw is bellow. In your humble opinion do you believe this will be okay or should I move the March pump to its own power source?

Heat strike water + PID (2000W element - 16.7A) - 30 min (17.7A total)
Recirculate mash + PID (2000W Element - 16.7A on/off controlled by PID, March pump 1.4A) - 1 Hr (19A total)
Boil + PID (2000W element - 16.7 A) - 1 Hr (17.7A total)
Chill - (March pump 1.4A) - 30 min (1.4A total)

As you can see there will be time when the element (16.7A) and pump (1.4A) will be running at the same time and with the little bit of draw from the PID, push button switches and PC fan (~1A), I will be running at 19A which is 95% of the rating. However There will only be about 30 min max at which everything will be running continuous operation. Do you recommend I move the pump to its a separate outlet so as to not push the limits of the wiring?

Thanks again for your help

You will be A-Ok as is. IMHO - No problem.

The PID will draw less than 0.1A. The pump will draw less than you think (under 1A when running).

Ok, Now down to the real issue: The NEC rule does not apply to you.!!! It applies to the designing and installing electrical technicians. Additionally, you have a single outlet fed directly from a dedicated breaker and circuit. Even with this particular case the NEC 'rule' does not apply to the designing and installing electrician. It is a dedicated circuit. Ball game is over with no worries what so ever. Go for it and do not worry about all the dug up sudo issues mentioned everywhere.

I hope this makes sense and helps you.

Question to everyone using this setup right now:

When boiling your wort what do you have the PID set to?

 

[DustBow]

Turn it to manual mode, crank to 100%, then once you hit boil back it down to whatever you're comfortable with. Trial and error to figure out your preferred boil off rate

 

[jrb03]

I set mine to manual mode 100% for entire boil.

 

[Wagon_6]

I set mine to manual 100% as well. I usually have to back it down a touch to hit my boil off rate.

 

[cheesecake]

100% the whole time I have not missed my boiloff a single time

 

[inhousebrew]

Ah, ok. That makes me feel a bit better but I thought the point of manual mode was to be able to reduce the intensity of the boil so that the element wasn't firing the entire time.

not as much of an issue here with the smaller elements and batches, definitely have to back off for the 240v systems with 4500-5500w elements

 

[ddahl84]

I have a single element 3000w 120v system and have to turn it down to 70%-73% to keep from boiling over 7.5g. It basically depends on your system and kettle size.

How many amps does that pull?

So I was looking at ways to attach the heating element to the pot/kettle/keggle. Not my original idea but it seems like a good way to go.

http://www.theelectricbrewery.com/heating-elements?page=7

Also found this 1650w heating element for cheaper than graingers.

http://www.zorotools.com/g/00065662...medium=referral&utm_campaign=AmazonProductAds

Through an outside source of amazon. $9.99 plus $5 shipping. Cost less shipped than grainger.

Hope this helps someone.
