Default HERMs vs. RIMs

What are the advantages and disadvantages of each type of system?

I would very much like to build something similar to:

http://www.homebrewtalk.com/f11/my-new-herms-setup-39422/

But, I need to really understand why HERM is "better" than RIMs or is it?

Where is a good place to find plans for both types of systems?

Thanks

I don't know if this is so much of an explanation, but this is a great site for ideas on your system design. A lot of nice elaborate systems, as well as some very simple ones.

I can't remember who it is (I thought it was ScubaSteve), but somebody on here has a really nice metal Single Tier brewstand, painted bright green. I don't recall if it was even a Rims or a Herms setup, but it was very nice. I can't seem to find the picture now...




EDIT: Upon looking, ScubaSteve does have a really nice wooden stand:

ok a Herms system usually consists of the wort running though copper coils submerged in water. its used to control your wort tempurature. this system usually takes a lot more space, but the pluss side is its not in direct contact with the heating source.

a Rims system consist of the wort passing by a heating element in a pipe that has a tempurature controller monitoring the temp also. but the problem with this is it is still in direct contact with the element so it is possible to burn the wort..

when you plan on building a system like this all the little things add up becuase your not just dealling with 3 pots and 3 burners.. now your going to need a pump.etc

RIMS stands for Recirculating Infusion Mash System.
With a RIMS system, you are directly heating the wort, either via a water heater element mounted into the mash tun, or via a gas burner mounted under the mash tun. In order to avoid scorching, and to ensure a uniform temperature through out the mash tun, the wort is pulled from the bottom of the tun and pumped back up to the top. One example of a gas powered RIMS would be the Brutus Ten.
The method described above, of mounting a heating element into a pipe and passing the wort over that, would be another type of electrical RIMS.

HERMS stands for Heat Exchanged Recirculating Mash System.
With a HERMS system, you are never directly heating the wort. Instead, you heat the water in the hot liquor tun, again either through electric or gas, and then you pump your wort through a heat exchanger coil mounted into the hot liquor tun, before it goes back into the top of the mash tun. Because the heat exchanger is indirectly heated, it is thought to be easier on the wort, avoiding any scorching or carmelization.

Well, obviously I prefer a HERMs... heh

It just seems like the more natural choice to me... you have to heat up your HLT anyways, might as well put it to good use.

+1 on HERMS... for the reason he stated, and the fact that you are not direct heating the wort.

Default HERMs It IS

Ok, from my reading HERMS was superior and if I am going to spend that kind of money I don't want to wish I had something else from day one.

Now what?

I see that most people use kegs in their systems, is there a reason for this? Is it cost or are they better than the pots that can be bought commercially from williamsbrewing.com or my local brew shop?

I want to balance expense with quality but DEFINETELY error on the side of quality.

I really appreciate everyone's feedback, this is a great forum.

Joe

A 15.5 gallon SS keg is much cheaper than a 15 gallon SS Pot.

But it is essentially the same thing....a Stainless Steel vessel.

And as far as cosmetics, a SS pot is nice and shiny, but you can polish and buff the kegs just the same.
Bobby_M has a nice thread on keg polishing.
