Weldless 2400w element

[FireKitty]

Hi folks, I finally got my 2400w weldless element from Mac's store wired up, and had a few questions due to what the sparky said when he gave me the goodies...

He reckons that this particular element 'will keep on getting hotter and hotter without a thermostat shutoff' - is this true? I assumed that the wattage would limit the temperature somewhat and stop the piece from self-destructing...

Any input or advice here? Could have posted in the newbies corner, but seemed more appropriate here in ElecHardware.

They are widely used in this application and work. I use the welded type but same same. Remember they are immersed in liquid an constantly transferring heat. You should not run dry.

keeps getting hotter and hotter till what? it becomes a supernova? :laughing-rolling:

without a thermostat shut off or regulator it just has the on or off ability. You wont be able to get the liquid to a specific temperature- thus have the ability to run the still slower

Keep it immersed and you'll be fine... :handgestures-thumbupleft:

Thanks folks - think the fella in question was just a bit in the dark on how distilling works :)

He also added an earth wire for me to attach to grounding, despite having a 3-pronged power cord - is this normal?

Cheers :handgestures-thumbupleft:

Its for grounding the boiler so weld a screw on the boiler and ground it that way i was going to do the same but my sparky pointed out that with a welded ferrule the tri clamp contact between ferrules conects the earthing on the the element in your case though i assume the seal on the weldless element will prevent direct grounding of the boiler so to be safe i would definately earth the boiler with that wire :handgestures-thumbupleft:

Some clarification from your sparky is needed.

The element in water will heat up. As it heats the resistence increases. My 2400w elements run at 2230w and 2250w once hot. Which is ok and will vary depending on exact input voltage, it does vary in Australia. The elements have a given physical size, the size against the wattage is our heat density. The heat density of an element determines what it can heat successfully. These are ok for wort.

What I think your electrician is leading to is they do not have boil dry protection to prevent them overheating. In the case of either the elements being run out of water/wort, or shit being burnt onto the elements preventing heat transfer into the water/wort then the element will overheat potentially then becoming dangerous.

Bullshit !

What's your problem this time ?

[OzKev]

Maybe it was a server error? My post has gone, the repost has not yet, your attitude seems the same.

[MacStill]

nothing was deleted, there was no server error, my attitude is fine ;-)

I put back the post you tried to delete after I had already replied ;-)

Wouldnt be like the mods on AHB to delete things that were posted to help members ;-)

Think you should check your own attitude before gobbing off ;-)
