not sure if i spelled that right, but i'm talking about the water sitting at different temps when heated with an electric coil (i've run into this before). see, when i first brewed with an electric kettle (my own frankenstein setup sources mostly from highgravity.com), i checked the temp in my HLT and saw a certain temp, but when i transferred it into my cooler mash tun, the temp was about 15 degrees lower than i had checked. this was because it wasn't all the same temp.

i'm currently setting up a Kal setup... and i'm wondering if ths is going to happen again where my temp probe reads on thing but the "whole" temp is lower than it's reading

thoughts? am i missing something painfully obvious? if so, please ridicule me as you wish but let me know Smile

Nope! Not gonna happen!
That's the beautiful part of this design... Well... one of them anyways!

If you build per Kal's recommendations with two pumps you will use one as a Wort Pump, the other as a Water Pump. The HLT is continually circulated and there is no possible way to get stratification this way, as you are pulling water from the bottom of the kettle (passing by the heating element). The temp sensor is in-line on the out-flowing plumbing of the vessel. You will measure the temp of the Hot Liquor just past the output valve of the HLT. This makes for EXTREMELY stable temperatures and VERY accurate temp measurements.

I do wonder though if on your old system maybe a lot of the heat loss you witnessed was parasitic loss from the Mash Tun. If you weren't pre-heating the MLT you would see a huge loss of heat like that.

Kal, if I missed anything here, by all means expand upon the topic.

To avoid stratification, our system uses a pump to circulate the water in the HLT Because of the circulation, the temperatures are evened out and the outlet probe will read the proper temperature. Now, whn transferring the water to the mash tun, you need to calculate how much extra heat is needed to compensate for the tun temperature as well as the grain temperature to be able to be at the mash temperature.
