I'm slowly getting all my parts together and finally dry fit up my rims tube. The element is a 6kw ss chromalox process heater. Watt density was around 40w/in2 iirc and was less the ulwd ripp elements. The tube is 2.5" and 28" long with triclovers on both ends. I had a 2" fpt welded to a tc ferrule and that's where the element threads in. The other end of the tube is just capped. The cap is made from a short ferrule with a piece of 20 ga ss welded to it. I had spare ferrules and it was cheaper to weld up a cap rather than buying one. The plan is to pump into the bottom of the tube, out the top, and recirc back through the pump whatever doesn't go to the mash tun. The cross has tow valves, the top goes to the tun, the left one is the recirc back to the pump. By doing this I'll be able to do a full speed flow through the tube and keep temps constant while getting just what I need going into the tun. The right leg of the cross is where the temp sensor will be going to the auber 2352 pid that runs the chromalox scr.


I used 1/2" polypropeleyne cam locks from proflow and they've been working great on my pump and chiller the past few brews and will have them on the whole rig once it's done.

Enjoy and let me know what you think.

Gorgeous. Nicely done.

NINJA EDIT: Any idea how much volume is inside the RIMS tube?

Just shy of 1/2 a gallon for the tube itself, so with the element probably a 1/3 gallon.

Just a few questions. Is the RIMS tube going to be used as a tankless water heater or going to be used simply to keep the mash at the proper temperature? What size batches do you brew?

I planned to be able to to on demand sparge & strike water plus be able to step mash. It should be able to do 0.325 gpm from 50-170 if I can keep a bit of insulation plus the larger volume of the tube was intended to be a buffer and smooth out my temps heading to the mash tun during recirc and sparge.

I do both 5 & 10 gallon batches now and once the rims is up will make the big 10 gallon batches easier when I'm using keggle mash tun instead of one of my coolers.

Unless it ends up being too much wort held up in the tube I'm stoked to see how it works.

I was curious because I do not do on demand sparge water but I do 10 gallon batches with a 1500 watt element. It is more than enough to keep the mash temperature stable. If you are doing on demand I understand the element size. I don't step mash because the malts I use are fully modified and one would be foolish to step mash with a fully modified malt.

I'm curious about the recirculate part. I am putting my rig together as we speak, and wonder about the ability of a larger (4500w) element to cycle on and off, and keep a steady temp back to the kettle

I'm fairly certain that rocks!

I have seen those around but decided to go the traditional route. So what kinda circuit are you on? Will you be able to crank it to 6k? I'm really interested because I'm using a 5500w on a 30a circuit (actually 50a, but my system is designed for 30a).

Electric hot water on demand is not very feasible.

With a 6kWh Heating element you could do about .8 gpm going from 120 * F to 170 * F

you could do about .35 gpm going from 50 *F to 170 *F.

For 5 gallon batches I guess it might be practical if you use your house hot water heater to start, but for 10 (or in my case 45 gallon batches), the flow rate starts to become less practical. Especially sine I dont have hot water where I brew.
