Immersion heater on an esky

gibbocore · Post by **gibbocore** » Saturday Sep 15, 2007 3:37 pm

Hey guy's was after some thoughts, i was thinking about installing an immersion heater and getting a new fridgemate so i would have a thermostat heating device on my mash tun, i gathered as well to avoid scalding that i'd need a system of churning the grist. What are the problems i'll face or will it be a great device that will elliminate the need to be boiling water and watching a thermometer etc..?

Cheers.

The only problem I can see is keeping the pump from being clogged with grain, and the sediment from wearing down the moving parts.

I think it might be better to move the immersion heater around in the esky as it is heating? Not sure how you would do this but it is the only real solution I could think of.

Cheers Chris!

Something else i thoughrt of was perhaps using a drill or other motor device to rotate a bread mixer or something to that effect inside the esky?

Its one of those big rectangle esky's, i'd probably steer away from rthe recirc idea mainly due to cost, pumps start getting expensive as to welded ss bits.

On a side note, remind me to alway's use rice hulls if i am using wheat malt!!! Very painfull, added a good hour and a half to brew day.

Your enthusiasm, & the effort you put into trying to answer every single post on this forum, is appreciated but I suggest you do some research on HERMS & RIMS systems. It is a common, & real solution.

Yes, but it sounded to me like he wanted to put the heater in the mash tun... Maybe you should do some research on the OP?

what if the heater was in a steel section filled with water that was then immersed in the grist?

You would still need to circulate the liquid through the mash or constantly move the assembly to avoid hot and cold spots.

thoretiaclly water should even itself out

Tell that to the water.

It will over time, but it will take longer than you have.

hence, should...

i know what you mean, i'm happy to stir occaisionally, just want to put my trust in a digital ragulator i guess as oposed to a candy thermometer.

A digitalised mash tun... There are some great possibilities there.

I reckon get a hand held immersion heater - it'll allow you to adjust the mash tun temp if you didn't hit the right temp at doe in or if your mash tun isn't very well insulated - to maintain the temp

You could also use it in conjunction with the HLT / Kettle burner to speed up the time it takes to get the water to strike temp and getting the wort to boiling point

I use water heater elements and submerge them.
