Before I get flamed, I am not insinuating anyone reading this forum or post is a dummy. I have received a few PM's lately about a post I made in the not too distant past about RIMS heater assemblies and the way I approached it. I am not an expert but my assembly works. If anyone intends to build one of these contraptions maybe this thread will act as a resource and help you.

How degrading... I feel insulted.

No, really, nice work

I like the diagram and the associated parts list. Nice work, keep it simple, I like that. I found that most of my inquiries are about how PIDs and SSRs work together and how to wire them up.

This is nice.

Nice post, and I agree.. Rims for Dummies.. Herms is definitely the way to go. :rockin:

Hehe... nice post and write up! If you could post the parts list as text or HTML, that would be helpful. Just so lazy people like me can copy/paste the URLs.

Here are some photos of the finished product. I made mine out of 2" 304 Stainless Steel Pipe but it can easily be made out of copper to decrease the cost. The clamps for mounting are Corvette Stainless Steel Exhaust clamps purchased on EBay. Please note that the 1/2" NPTF to 2" NPTM bushings were out of stock when I built my RIMS Heater assembly so I used two bushings. I checked today and the 1/2" NPTF to 2" NPTM bushings are back in stock.

Item #7 in your table shows 1200 watt, s/be 1500.. Of course I was one of the PITA people bothering you with pm's. Don't most heater elements have a zinc plating and is that of any concern health wise to us beer drinkers?

Thanks Guy !

These elements are for potable hot water heaters. I don't know if there is a zinc coating or not, but if there is, I doubt it would cause a health risk. The daily recommended dosage of Zinc is 15mg. It didn't take much more than that to plate that element and the coating will last for years.

What did all that stainless cost you? I make them out of copper for $50 or $60 in material. I can't imagine what the stainless would have cost!!

Consider me dumb as a stump.

Great post!! I am going to get this project underway once I am in a house and not an apartment (October cannot get here soon enough!)

Any benefits/issues with rigging up two of these in-line for other use such as heating HLT or bringing wort up to boil temp faster?

what happens if the element goes dry? Does it burn up? and if so, how do you prevent that from happening?

I am looking at a Rheem element SP10868LH 120v 1440 Watt

Resistored Stainless Steel Heating Elements
Preferred Parts resistored stainless steel elements feature a low watt density design with an outer sheath of Incology® 800 to resist failure from “dry firing”. Built in resistor helps prolong anode life for greater tank protection and longer working life.


Costs more !

Mine is mounted vertically so the air is located above the end of the element. Just don't turn it on until you get liquid out of the top hose.

I have been accumulating parts for this build and one question comes to mind - how do you close off the end of the heater element to avoid electrocution? Seems like it would not be an off the shelf part.

There's a gasket that comes with the heating element that seals it to the ss or the copper.

Mine is very similar, but with a few differences:

Used Auber RTD instead of thermocouple: Liquid tight RTD sensor, 2” probe, NPT Thread [PT100-L50NPT] - $29.95 : auberins.com, Temperature control solutions for home and industry

Used 1 1/2" SS pipe from BFO: Stainless Steel Fittings

Used a 5400W 240V ULD element, but run it at 120V.

I covered the dangerous end of my element with a PVC cap.
After I took the pictures I attached the wires and dipped the end of the element in Liquid Electrical Tape. I was very careful and taped off the portions that I did not want covered and it doesn't look half bad. I also plan to put a lexan sheet over it for safety so nobody gets burned by touching it the heater. Safety is no accident.;)

Sawdustguy and bakins, thanks for the information...Just the websites to order the parts from is very helpful. :)

I just purchased the parts (mentioned above) to make a 1 1/2" RIMS heater. I went with the Auberins PID controller and RTD thermocouple for better accuracy. I also chose the ultra low density heating element made from SS nichrome (better resistance to burnout if operated dry).

Do you take it apart to clean it once in a while?
Shouldn't need to assuming you run a cleaner (PBW, detergent, etc.) through it after brewing. It's the same logic as using a March pump, you should only need to take it apart if you encounter problems.

With that said, if I goofed and accidentally ran the RIMS element dry, I would certainly take it apart to scrub off the burnt wort. ;)

Doesn't get much simpler than that! Nice work. People mare very hesitant to provide electrical assistance on the forum because of the liability with liquid. Thanks for this.

Having done so, I ran near boiling PBW water through it again, and again, and again. (ie, several different batches of PBW water) Then near boiling rinse water the same.

I like your post very much and I think i am going to follow your build. How did this device work in practice? Did your efficiency go up at all? did you have any problems with overheating?

Why in your parts listing do you specify a 2"x6" SS pipe(S4N2x6), but the part number you specified is a 2"x10"(S4NX10) piece of SS tubing?

Which is correct? I assume the 10" pipe, since the heating element you chose is 7+" long.


Also, do the example photos use the same parts? Seems to use more busings that in your parts list? Is the two bushings at the bottom of the Tee's 1/2" to 1/4" bushings?

I had to use 2 bushings because they were out of stock on the bushing I wanted. I didn't want to wait so I did it with 2 bushings. The supplier felt bad they weren't in stock so he gave me one of the bushings for free. Kapish.
