Herms/rims Systems $$$$

With anyone's system, the mash temperature cannot be hotter than than the HE when ramping.

I didn't say that.

I didn't say that.

I know you didn't. I did. You said you didn't care what the temperature of the water in the HE was; I was simply pointing out that if the flow rate is normal, then neither the temperature of the mash nor the wort coming out of the HE can be higher than the water in the HE.

Do you have to know the temperature of the HE? No. In all the batches I've mashed with my HERMS, with only the last one - that damn CAP - did I need to know the temperature in the HE. When it started to skyrocket and the mash wasn't following, it was a sure sign that I had no flow in the system. I was really glad I could monitor the HE's temperature that cursed day.

I know you didn't. I did.

I know you did and I didn't.

Since I decided to make my new electric brewery a HERMS I've been doing a lot of reading up on the subject on many sites and I have to say this is just about the best thread I've come across.
One question I have relates to the position of the HE. All the systems I've seen, the HE is usually a pot and it sits underneath the HLT or MT. I am planning on using a 5kg aluminium fire extungiusher with the top chopped off and a 2400W element stuck up its bum. From what I have learned from this thread is that the best place to put your probe that drives the HE is right at the return to the MT. Therefore the shorter the return from the HE to the MT the better. My plan is to have the HE sitting at the same height at the MT with a short (maybe 6") pipe coming out of the HE and straight into the MT. Today I was experimenting withs ome 1/2" copper pipe trying to wind a 4"dia coil. I finally worked out how to do it and I should have about 6M inside the HE. The only thing that concerns me is the ability of the march pump to have enough head pressure to get a return flow. Will having the HE at the same level as the MT make the pump work harder than having it sitting at the same height or below the pump?

PS Kirem, I know you know you did and he didn't LOL...

G'day Browndog. I have my pump push up to 1.2 mtrs then through 8mtrs of 1/2" copper (in the HLT) befor coming back down to the mashtun. I don't think you will have to many hassles. I wouldn't put the HE below the pump, if you make the pump the lowesy point in your plumbling then it will always stay flooded (primed)

Thanks Razz, heat exchanger up with the tun it is then!
