304 Stainless Steel

Stainless steel provides an attractive, clean finish with low maintenance cost
304 stainless steel has a high resistance to rust. It withstands corrosion from most oxidizing acids and is often used for kitchen and food applications. However, it is susceptible to corrosion from chloride solutions (notably saline environments with high amounts of sodium chloride). Chloride ions can create localized areas of corrosion, called "pitting," which can spread beneath protective chromium barriers to compromise internal structures. Solutions with as little as 25 ppm of sodium chloride can begin to have a corrosive effect.

Isn't OXI a sodium chloride solution?

Am I an idiot or was this chilling into the fermenter a new thing. When I watched the videos at the start it either wasn't clear or wasn't mentioned. It does however make sense now after watching the above video

I had the version 1 and the instructions aid chill into the fermentor

I think that's how they intended it to be done from the start but I know alot of people weren't clear on it and they put out one of their instructional videos emphasising why it was most efficient to chill straight into the fermenter and gave a good explanation of why that was

If you mean Lidl W5 Oxy Power then no, its Sodium Per-Carbonate

By recirculating back into your boiler and letting it stand to do not catch more of the cold break instead of having it all go into your FV?

I was reading I think on Brulosophy.com that the cold break isnt bad to get in the fermenter and may be good, i think he did an experiment and the cold break one cleared up faster.

It's what commercial brewers do,even the good,the bad and the ugly
They know what they are doing don't they

I'm putting center diptubes into the BK next, as with a spider it's just break material in the bottom. Doesn't seem to effect the beer in the slightest and way easier to clean in place.

Yes Will, its what I mean. Therefore safe to use I suppose?

Quick update - after the new pump filter arrived my next brew day was close to perfect. I used leaf hops, around 150g in total, no hop spider or bags were used. GF performed great, no further issues with the filter, valves etc. I've recilculated the  wort for 2-3 minutes into GF and transfred then straight into the fermentor. Wort temperature was 20C during transfer. The counterflow chiller is fantastic.  Again, OG much higher than expected, great clarity. I will buy the hop spider though - just for peace of mind

[Archsnapper]

I bought the hop spider for the peace of mind, as well. It's grand with a "normal" amount of hops, but I made an amber brew the other day which required quite a lot, and it was rather full. I ended up twisting a piece of clothes hanger to allow me to let the spider deeper into the boil and stirring it's contents for some time.
Such is life - nothing's perfect!

New control box on the way

Oh goodie!!

[molc]

That's a win all around, as I'm sure you can us the control box with any system if it's sold separately. Nice one!

Looks great, would be slightly restricted to a 2kW(?) & 21L final volume of Grainfather - the PID & other variables probably wouldn't be user changeable.

You'd have to rework it to handle two Keggle elements.

[molc]

Oh well, would just have to get a grain father then... >
