Direct Heating Mash Tun - Burning

[Batz]

Using the mashmaster do you set the temp of the urn and then recirc to raise the temp to that of the urn (would be a bit lower depending on losses, I guess).

Spot on how I do it Screwy,if you use a drop in coil you will be left with it full of wort after recirc.

You could drill the lid I suppose,you need to keep the coil just off the element as well.
I'll go 1/2" tubing for ease of bending and finding fittings.

Easy to finish off the project mate,you need a kettle element,few metres of 1/2" copper tube,rest of the gear I may have floating about.Lets get together for a beer and knock it up hey?

Thanks Batz, in the bigger urn the coil can be wound to sit outside the element, I think that would work? 1/2 inch is easy to source from scrap.

Andrew, for urn bits at reasonable prices try J G Thomas in Bayswater WA. The usual suppliers told me there were no spares available for my old Langco. J G Thomas had replacement parts, new simmerstat only $23.90

The plumbed in coil would still have wort left in it too, but not as much I guess. Might plumb it in! Do you use the snap on hose connectors?

I plan on having my HLT sparge water run through the herms coil at the end of the recirculation, seems it would be a good way to clean it, is this how you have yours setup batz?

Screwtop, I plan to use a smallish S/S pot for the herms with an elcheapo BigW kettle element. I figure if I keep the volume of water in the herms as small as possible then the heating cycle should be more predictable. Some good info here

Gravity is my friend as far as wort left in the coil.
I use those plastic wing nut type connectors you can buy from boating places.



They come in straight or 90,and screw straight on to 1/2" bsp nipples.Also have 1/2" barb for the hose.

$5.95 each

Andrew, interesting stuff, as recommended use a small vessel for the heat exchanger. That was why I'd considered using the drop in coil in the 45L urn. Thought it might be better off being preserved for use as something else, maybe HLT or something in the future once I can get a hold of a smaller urn.

Have some of those hose nut and tails Batz, thought the barb might crack off too easily being plastic so was going to try the snap on type.
