Cheap 10L urn

[scooterism]

Just having a think on how to make a 10L urn on the cheap.

I have a 20L Big W s/s pot, but what to do for an element?

of the 4 elements I'd suggest: 'The Element Of Fire'

^^ HA!

just like to add, I'm using the search function.

But there are so many posts regarding elements, kettles to dishwashers even tumble driers..

end of the day, I just want safe and simple.

Keep an eye on eBay/Gumtree, you'll pick one up for bugger all.

Kmart kettle element. Cheap, safe, simple. (Get a spark to check everything)

Kmart kettle element.

Did this exact thing myself (link to post with more detail), and added a 1/2" ball valve and some insulation:

If you choose to do it this way, learn from my experience instead of tearing your hair out trying to fix a leak:

First stage was fitting the element into the pot -- the thin pot walls made it a bit tricky at first, but once I filed down the threaded posts on the back of the element to get more compression on the silicone grommet that came with the cordless jug, it was tight as a drum and didn't leak everywhere

Yep, I'll go the kettle route unless an urn comes along.

Cheers for the info above. :super:

Running two off the same circuit isn't going to work is it?

*** Note: I'm an electrical designer and not an electrician, so caveat emptor / do your own research and all that... ***

My notes say the KMart kettle element pulls 8.7A (2090W @ 240V nominal), so assuming that the following are true, you could technically run both off the same circuit:

• the circuit is fed by 2.5mm 2C+E TPS
• there's nothing else running on that circuit
• you run each element from its own GPO on that circuit

It would be much safer to run each element from its own GPO on separate circuits.

But then, do you really need a second element for 10L? Matho has an element sizing calculator on the forum that might be fun to play with.

Thanks for the reply, two elements? I'm impatient and thinking out loud.

Questions about the kettle element, Do I need to keep all the black plastic bits or can I just make a new metal disc w/ the appropriate holes?

I watched this and it seems like the plastic maybe not be necessary, only acts as a clamp so to speak.

other question, should not the earth also contact the pot as well?

Good news to add, at my work there are about 40 electricians and I was going to hit one up to take care of the wiring for me. Well one came and saw me today and asked if I can do a welding job for him, so I'm sorted there..
