Default eHLT: Recirulation Pump or Stir Motor?

I just wanted to see what everyone's input is on keeping water flowing in an HLT. Currently have a single tier, single pump batch sparge setup. I would assume moving liquid would heat faster and more evenly. During initial HLT heating I could use my march pump to recirc, however once mashing I would like to use March to move wort through HERMS.

Would I be better off stiring HLT during mash, getting a second pump and using it to recir water, or just leave it alone?

I thought I could leave mine alone, it doesn't work as well. I bought a cheap pump off of ebay and constantly recirc.

I did a test using my pump to recirculate water.
I found that the pump cooled the water by about 5 degrees. This was
about 5 feet of hose and the pump. I started with 140 degree water
and ended after it dropped to 122 degrees.

I wasn't heating during the test - only recirculating.
Thus I concluded that I should get a motor and stir.
I thought about an ice cream motor, or a regular AC motor with a 30-60 rpm speed.

Squeeky,

Go get yourself one of these motors - 63 RPM Rotation CCW for $18 and then biuld this:









You can make a very simple prop for it and the lid is a very cheap SS one from WalMart. It really works very well and is a lot less than getting another pump.

Just saying.

Haha, leave it to PJ. I actually still had that bookmarked from wortomatic back in 09. I'm gonna brew Saturday hopefully for firt ebrew. I'm just going to hand stir during mash and make the pid work a little harder.

Even without stiring I should be able to regulate mash temp with still water just up/down pid and monitor temp in mash.

Do not monitor the mash temp, it will overshoot wicked. I moved my TC to the HLT and its been perfect ever since (3 deg differential). As far as the stir motor, I stole the motor/gear reducer out of my kid's electric ATV and made a blade out of copper similar to P-J.

Yea my TC is in the HLT. I just assume stiring, while recircing my mash through HERMS coil would distrubte heat throughout hlt better then still water.

You make an excellent point. Yea, measure the mash temp so you know the differential between it and the HLT temp. But, use the PID to regulate the HLT temp not the MASH temp. It will only be a few degrees.

Keeping the HLT water in motion helps a lot in keeping the temp stabilized.

Bit faster, smaller (2lbs) and cheaper.
