Title: StockPots
Post by: johnrm on May 22, 2014, 10:29:32 AM
Great value in Stockpots...
http://m.ikea.com/ie/en/catalog/products/art/50112528/#/ie/en/catalog/products/art/00101160/

I picked up an induction hob, but the Stockpot I am using is not induction ready :(
The above one is!

I was looking at them too. My cooker is induction so I thought that could be handy in the winter for making small batches indoors.

So everyone knows:

Induction hobs ONLY work in conjunction with magnetic materials, so:

Aluminium, Copper, Pyrex, etc are no goes

Enamelled Steel, Cast iron ware are great!

Stainless for this purpose comes in two forms magnetic and non magnetic.

SS is also known as: Ferritic and Martensitic stainless steels are magnetic. Austenitic stainless steels are non-magnetic.

Now most of our keggles are magnetic. Just see if a fridge magnet sticks!

Some professional cookware ( see Nisbetts.ie ) have a layer of magnetic ss so they are induction ready!

I love my aluminum pot (on my gas boiler) but never ever use aluminum on a ceramic hob. It'll scratch the f*** out of it.

I have a 7l stockpot, thought it would be good on a portable (Aldi) Induction hob for demos.
I then found that its non-magnetic, so need the pot too.  ::)

I just picked up the hob in Aldi and discovered my stockpot doesn't work with it. Luckily, I'll be in Ikea next month anyway, so I'll add the stockpot to the shopping list.

The aldi ones are 2kw. I must test the boil times to see how it performs.

Will do John.

Tube did a test between his one and gas (http://www.nationalhomebrewclub.com/forum/index.php?topic=6843.msg86764#msg86764).

I've only used mine once so far to heat a few litres for steeping. I wasn't timing it but it was as good as the very expensive induction hob in the kitchen! The one that she picked out  >:( Because it had shiny chrome handles. FFS!

Lads not sure if Ikea is really that cheap :/
10l for €35.00 doesn't look like a great bargain if you'll compare it with The Homebrew Company (http://www.thehomebrewcompany.ie) offer.
What about SS 21l pot for €39.95, 33l for €59.95, 50l for €76.99 and 70l for €81.99??

When was this because they are not on the main site and they are nowhere to be found in my local Aldi ? In fact i have not seen them advertised for at least a couple of weeks now. :D

Can't see why not. Both Ikea & HBC are SS.
Title: Re: StockPots
Post by: Garry on May 29, 2014, 09:52:48 AM
Most cheap stainless steel pots will not work on an induction hob. The base needs to be magnetic. If they don't specify that it's suitable for induction, it usually isn't.

I've sent HBC an email to check theirs.

Not all SS is the same. There are different grades because its an alloy.
Title: Re: StockPots
Post by: Garry on May 29, 2014, 10:11:32 AM
Just got an email back from Shane, their pots are not suitable for induction hobs  :(

@Jacob, mild steel (the common stuff) is always magnetic. Stainless steel is usually non-magnetic but can be got magnetic. Even SS pots that are suitable for induction hobs, usually only have a magnetic layer on the base.

@Qs, mild steel is an alloy too; iron + carbon = steel  :)

@Jacob, I don't get it fully either, but once there is an aluminium layer laminated in the base of an otherwise s/s pot then it works. Copper does not work either, or Glass, apparently thats not magnetic  ::)

See reply #2 on page 1 The aluminium is there to provide better heat distribution if its put on a gas burner!

Good quality, professional kitchen pots are usually either heavy Aluminium with a layer of SS in the base so it works on induction

Or:

All SS with a layer of aluminium in the base for heat transfer.

That is why the bases are about 4 to 6 mm thick and the pots are blooming expensive.

The thin ss pots we are talking about are just thin SS with no thick botoms!

Could you just have a base of an induction pot on your hob, then stick your non induction stock pot on top of that? Would the heat still transfer?

You can use a  hop adapter plate (http://www.amazon.co.uk/Frabosk-Large-Inductor-Adaptor-Plate/dp/B004JMV0M2/ref=sr_1_3?ie=UTF8&qid=1401360003&sr=8-3&keywords=induction+hob+plate) but you won't get the same efficiency.

Induction hobs effectively turn the base of the pot into the heat source. That's what makes them efficient. You can take a boiling pot of water off an induction hob and the hob will be cool enough to touch without melting your finger off. (Use some common sense if you want to try this at home!)

Using the adapter plate, the plate becomes the heat source which then has to transfer up to the pot. It would be the same as using an ordinary electric hob. So you would not be getting any benefit from using induction.

It would be the same as using the adapter plate I'd say? The plate you weld to the base would only be welded around the outside and not fully fused to the base.

You could put thermal paste between the plate and the pot before you weld them together.

That might just work? No need to weld it either, just use thermal paste?

With all the faffing about you'd probably have an induction pot bought though.

Another thing worth noting: the flatter and smoother the base of the pot, the better it will work on an induction hop. So if you get a cheap pot with a thin base, it might warp over time and not work anymore :(
Title: Re: StockPots
Post by: DEMPSEY on May 29, 2014, 06:35:37 PM
Do any of ye ever used thermal paste and if so how strong is the bond. Would the prolonged heat of a boil not cause it to weaken.
Title: Re: StockPots
Post by: imark on May 29, 2014, 06:52:52 PM
Alternatively, drop the plate into the pot. It'll work fine through the pot base. You can take it out and wash it after the boil.
Title: Re: StockPots
Post by: imark on May 29, 2014, 06:56:22 PM
Also, the pots that are sold as non induction ready will still work in some cases.
I bought one off mybeerandwine    that wasn't supposed to be induction capable but it actually is.  Basic principles is if a magnet sticks you're good to go

Found this pot on Amazon. 19L stock pot. Not bad. I'm considering it as a HLT/kettle for small batches in the winter. Reasonably priced too.

Would the aldi ones be strong enough to both boil and hold the weight of a 5g batch? I've a 36l brew kettle that a magnet sticks to. It's got a very wide base though.

The aldi hobs are 2kW so don't expect it to get you to boil temperature quickly. It's sufficient to maintain a rolling boil though.
I have a 3kW hob and it's the mutts. I'd recommend shelling out extra for the more powerful hob if it's going to be your main brew kit.
