Will ya tell me the coil and pot combo you get.  Id be happy to go in on it if you are interested

I ended up buying the 12L Thermo pot and bought the smallest SS coil I could find from the UK, which is not very small. The height of the coil is 20cm and width is 15cm, hopefully the bigger pot will accommodate this. If not I might try and bend off a few meters or failing that back to the drawing board. I should have all the bits by next week, will throw up a pic when built.

The goodies arrived yesterday. This coil looks like it will fit the 12L pot ok, not too sure if it would fit the 6L though. As you can see from the pic it's not the width that would be an issue, but the height of the coil. There's enough room in this pot to leave some clearance for the heating element at the bottom.

Going to put it together this weekend hopefully.

Bit late to the party here but another option for a herms coil is the smaller chiller from get er brewed.

I've read somewhere, probably here, that running hot acidic wort through copper is not the best option.

Keeping the inside free of any copper oxide would also be a problem due to the reactive nature of the copper with the acidic wort.

Not Vast knowledge but have been messing with herms for 3 or 4 years now
Shanna has them there on another current  thread
Lots of different types out there, avoid cheap Rex ones, and see if you can get one accurate to 0.1 degrees, cheaper ones only 1 degree.
I and others use sestos but there are others out there.
Mines in a plastic lunchbox, one of these days I'll do a proper control panel.

My first herms was a small t urn 15l with 8mm copper coil, coil at 4 metres was too long, bigger bore 12mm shorter length is better I now have a pot with a coil from brew builder



with 5l and 3kw element and can ramp 40l a degree a min in 50sec, you can't do that with hlt

Have a think about where the probe will go to measure temp of herms return, important that it reflects the temp of the wort on top of grain and not that exiting pump.

I'm no master electrician as you may gather from this post but i'm presuming you need to earth this to the side of the pot? Also is the electrical wiring connected to the element exposed underneath the pot, or have you concealed it somehow?

Its a double lined insulated pot. The earth is on a crimped connection and bolted with a small stainless bolt to the outer metal skin on the underside base of the pot, you don't need to compromise the pot.
Live and neutral go onto the element connections, there is a square I have cut out and that allows me access and I have covered and glued that with a piece of clear PP plastic to allow me easy access and stop water improbably water splashes getting in for safety
If you are going to use element above connections are not central so place element in the pot mark circle where connections are and drill accordingly.

IF YOU ARE UNCERTAIN ABOUT ANYTHING ELECTRICAL DO NOT ATTEMPT.

These coils which fit in the 6L pots are due back in stock at the end of February, as per the product description at the end of the page, for anybody looking for a small coil.

The website says they don't deliver internationally and I never emailed them to see if they would instead I used the concierge service with an Australian mail forwarding company. Think it cost me approx 80 something euro for the coil delivered.  Expensive alright but its a neat solution I'm happy with.

Pricey but it's the only coil I've been able to find, I've found places that will sell me the seamless stainless tubing but noone knows where I could get it cooled for me.

An update on this, while waiting for my element to arrive, decided to drill the holes for the coil. The coils are a lot longer than ch's. But won't know for sure,   the element should surround the coil at the bottom.



It's going to be a very nice addition to the brewery, also waiting on a bsp pt100 sensor from China, so that'll be a while. Can't wait till it's finished.

Probably know this already but make sure you don't seal tight when in operation.

The final few bits i needed to get mine together arrived during the week, also need to get the finger out now.
