Default Questions for electric herms guys.....

What temp do you keep your hlt at? And do you occasionally stir the mash or let it be? My first brew for some reason took a big temp jump, to 160f! after the pump ran for the first time. Which makes no sense, so I was continually stirring it in a panic for the rest of the hour.

This setup is driving me bonkers. Maybe a ranco in a thermowell isn't responding quick enough? I know it's spot on accuracy wise.

I don't know what temp my HLT is at, because I monitor the wort temp as it comes back into the MLT. I don't stir anything.

My mash hits the set temp pretty much dead on (within 1*F) and holds steady.

Do you constantly recirculate? How do you not know your hlt temp? What's your wort temp as it returns?

Do you put your coil in the HTL and recirc through that? I have a thermo well reading the temp of the wort as it returns back to the mash. The sensor then either heats the HLT water accordingly. In my set up I recirculate the mash water until the mash water is a few degrees above my strike temp. After I mash in the grain temp is lower but recovers quickly. I use a separate thermometer that I will insert in different parts of the mash and test until my mash temp is uniform. That's when I start my timers. I don't rely on timers to know when my mash is done, I use an iodine test. My mash is always recirculating to maintain consistent temps the whole time, as well as end up with clear beautiful wort.

wildwest...

I have my temp probe for the PID mounted in a little chamber at the output of the coil. I directly monitor the temp of the wort as it returns to the MLT this way. If the PID sees the temp falling, it bumps the heat on the HLT.

The temp of the work coming out of the coil is always within 0.1*F of my set-point.

I constantly circulate the wort.

Let me see if I can get a pic of the coil and temp probe....

here it is.

pump pushes wort into the left side of the coil, flows through the coil which is sitting in the HLT water, and comes back out on the right side of the coil. It flows right around the probe before headed out the hose to return to the MLT.

Well, la de da mr. fancy pants. We all don't have such extravagant setups.

I guess I need to do a water only run again, and try to see why the temp spiked like it did.

I have a regular analog temp probe in my MLT and I also have a K type temp probe hooked up to my BCS-460. Both probes are mounted in my MLT and I've been having trouble getting them to both read the same. I find that I have to stir while recirculating for about 15 mins to get everything to equalize. I find I have to have my HLT at 163-165 to maintain a 154-156 mash temp.

I keep my HLT a half a degree above mash mash temp, continuously recirculate the wort. HLT is continuously stirred. I control my HLT temp.
