Stratification
Stratification
How you you chaps deal with the stratification or layering of different temperature water in your HLTs? the first time i heated my new HLT up i was shocked to see just how the top of the water could be a nice steady 85c but the bottom inch as cold as tap water! Short of just stirring it all the time, does any of you have other methods of keeping the liquor an even temperature? I was thinking of having some kind of stirrer in there that comes on with the elements.

Re: Stratification
recirculate it with either a small pump or jug fulls from the tap back into the top, this should sort it out

Re: Stratification
I just give mine an occasional stir. That does the trick.

Re: Stratification
Yup. I just give mine a stir before I need to draw water from it.
I've got the temp probe about in the centre of mass of the water, so once it's stirred, it's normally within 0.5C of the target temp, and the PID takes care of the rest in a minute or so.

Re: Stratification
I use a pump to recirculate my HLT water, I pump with a valve on the output one direction to recirculate and the other to regulate sparge water flow rate
if of interest I could try to post a picture later in week of my latest creation

Re: Stratification
I ususlly forget to turn it off in time and the boil produces wonderful convection currents, just takes ages to cool down to 80 again

Re: Stratification
planning to brew in next few days, so will take some pics and post them
not sure I want to put steel into my beer (Stainless is not magnetic) - like the video though
