I am having a hard time maintaining consistent temperatures in my mash tun during the mash rest. I have a bayou classic 8 gallon mash tun with a ball valve and screen and a false bottom. Depending on the grain bill I heat up the strike water to roughly 160 to 167, add grain, mix, and let sit until temps start to drop. I'll then throw a little heat on it to bump up the temp while mixing thoroughly. The problem is that when I take readings, the temps vary quite a bit, 7 degrees at the most.
So my idea to maintain a more consistent temperature is to have a separate pot with 4 gallons of water on the stove with it set at the desired mash temp. Then place a submersible water pump in there and have it pumping water to my wort chiller, which would be placed directly in the mash. The water would then recirculate back into the pot holding water. I posted a picture to get a better picture.
I have tried searching for something like this but haven't found any information about it. So my question is does anyone see any potential problems with this idea, and does anyone know of a reasonably priced submersible pump, able to withstand heat, to circulate the water. Thanks in advance
