How much water in the tun?

I haven't had time to follow up on this. I think the 120v version I put together shows promise for 5 gallon batches with some insulation.

It maintained temps with no insulation and the lid off the tun (20gal Stout tank). So, It might do much better with the lid on and a lot of insulation around the tube.

I'm not going to have time in the near future to play with it any. If someone is interested in picking up the parts from me for half price, let me know. If not, I'll eventually get around to insulating it and testing again.

Did a similar build a few years back... still works really well. Putting a spring in the tube breaks up the flow and improves heat transfer. I clean in place, but the springs are also easy to remove. Don't forget the thermal fuses...

Bump. I'm in the market for a RIMS, and I keep thinking about getting the element outside the pipe.

Any further performance data? Problems?

Highly recommend. I used extreme temp heat tape.

Did anybody use that irims ?

I made for me first irims with 35mm ss pipe and 8pcs of 250w band heater that gives about 2000w.

I want ask how about parameters today i test heating speed and with uninsulated plastic tank. I use about 14-15 Liters of water, set flow speed at 2 liters/min.

With this setting i start heat water and resaults
time -before irims - after irims
00min - 13,0* - 20,0*
10min - 25,5* - 35,5*
15min - 33,5* - 44,0*
20min - 39,0* - 52,0*
25min - 44,0* - 53,0*
30min - 53,5* - 61,5*
35min - 59,0* - 67,5*
40min - 65,5* - 75,0*
45min - 71,0* - 80,5*
50min - 75,0* - 85,0*

Its about 1,5 deg/min at flow 2 L/min.

In addition, I must add that still a lot of heat escapes outside as I checked the pyrometer, the temperature was between 150 - 200 degrees.
