Herms Question

[scooterism]

So I'm trawling through the kabillion pages regarding herms set ups.

I'm kinda bewildered, what is the ideal heating element, watts wise?

Depends I run a 2400w immersion heater in a Big W 7.5 lt pot with 4mtrs of 1/2" copper for a standard 23lt batch ramp time just over 1*C per minute . Obviously the bigger the herms pot the longer the ramp times and that can be negated with a larger element output to a point as the bigger the pot the more power you need and everyone is different so it becomes what do you need.

Hmm, I hear what your're saying and I figured as much whilst researching.

Next question, is there a formula of sorts or is this a suck it and see approach?

How many litres is your mash tun/average batch size? From that you can derive how big your HEX should be, and how long your coil in the HEX should be. Contact Adr_0 by PM. He built an algorithm to help work this out. He may be able to plug your numbers in and work it out for you, maybe for a couple beers. And Adr_0, if you read this can you post the address of the thread you did that in? I had it bookmarked, but the site upgrade made it useless and the search sucks so bad now that I can't find it.

I find that a $7 kmart kettle and one of these https://onlinebrewingsupplies.com/herm-it-r-coil/hermit-coil work really well.

Have a look around pge 75 of Dedicated Herms Guide Problems and Solutions Thread . I didn't have a thorough look but I think you will find most of your questions answered there

I have a small herms coil in a PVC pipe with a kettle element. It will maintain a mash temp and rise at 1-2c a min.
If you have a herms coil in a HLT you will be able to .maintain a mash temp but may find it slow to ramp.
2400w is the max you can draw from a standard power point so this would be your "max"
