Stainless steel herms coil pre fabricated

Postby boab44stout » Tue Dec 15, 2015 17:10

Does anyone know where I could get a pre made hermes coil about 2 metres long as I don't have pipe benders or tools for stainless steel :|

Homebrew builder sells them not cheap but quality

Its not suitable for using star San with and its not shiny but I could always use another sanitizer and I already have the tools for copper bending.
Think also it has better heat transfer than stainless :hmm:

If its shiny you want then it has to be shiny, but you don't need to use starsan for a HERMs coil cos you will be boiling the wort after. :) In my HERMs days just used to run some oxi through and then a good rinse. ;) I might be missing something. :hmm:

My thoughts exactly springer their is no need to sanitise it as it is pre boil, I have never sanitised a mash tun.

As for it not being shiney it's going to be inside a pot so who will see it.

10mm copper pipe is simple to make a coil we have made a few just wrapped around a keg on the carpet

Well you can get seamless stainless steel pipe from a steel stockist. comes in metric 6,8,10,12,mm and it bends without kinking. Next time you visit a shopping centre or train station you will notice 1 metre polls set along where you are walking. They make great pipe bending poles when 2 people walk opposite each other twisting the pipe around them :party: ,or so I'm told :whistle:

Acid and copper don't go too well together.

I guess it would be a problem if you dip it in pure starsan. Diluted solution shouldn't be a problem?

Like already discussed no need to sterilise anything pretty boil. Videne works well on copper as it's iodine based

The topic is about a herms coil which never gets boiled???? Herms coils don't need sterilising as it the wort just flows through them for the duration of the mash. Prior to boiling. I think there's confusion about the herms here. It's not a chiller

The topic is about herms coils and what materials,could be used copper can be used both as a herms and also if wanted a wort cooler which gets boiled in the wort the last 15 mins to sanitize.
I understand all the concepts of herms as the coil is used to maintain a temperature when wort moves through the inside of the coil and recalculated through your mash tun.
Thermos pot is in turn controlled by a pid and relay sensors are used by pid to monitor and maintain a set temp by cylcling herms pot element on and off.

There are links for star San somewhere on the forum I would post but limited to my kindle at the moment.

As,with all chemicals care has to be taken as star San can also harm kitchen worktops due to acid . Trust me I learned the hard way.
Viodene seems a good option especially if I do make a herms and the coils been laying dormant for months and want to sanitize it.
Just in case some mould or yeast gets in their or circulate hot water through it
I think most of the time as most have pointed out a herms coil doesn't need sanitized as the wort gets boiled anyway but it's personal preforance at the end of the day.
Will build a herms pot next year as would like to do a stepped mash but I will not be doing so without consulting other members on here first As I don't want :electric: or :doh:

But why sanitize a herms oh dear!!!!! I can understand cleaning with oxy which I have done but there's no need to sterilise /sanitize it whatsoever

Hi Mark sorry about this I understand fully what your pointing out just trying to point things out as to if you wished to sanitize something copper that's all. I have used oxi clean on my wort chiller works fine but rusted the jubilee clips
