240V Element size for small batches

Some are probably wondering when I'm going to quit posting questions and build something. I have finally gotten 2 all-grain batches under my belt. Since I'm really new to beer-drinking, I'm thinking that I would like to brew small batches in order to have a variety of beer available. I can still use my keggle and propane for larger batches.

Most of the small volume e-builds I read are going with 110V. Other larger e-builds that use 110V are using 2 elements. I have easy access to a 240V GFCI circuit in my brew area, so I can't think of any reason NOT to use it.

I'm looking for an appropriate element to use in my 7.5 gallon SS kettle that's 12.75" in diameter. I've been led to believe that one should use the lowest watt density in order to avoid scorching.

Jrb3 seems to be doing fine getting 3 gallons to boil using a 1650 watt element in his 110V system.

I found the following 3 elements at Grainger and wondering if one of these - or any other that you might recommend - would work the best for me.

I'd like to be able to boil up to 5-6 gallons for the rare occasion that I want more.

3000 watt LWD folded element, 9" long:

2500 watt LWD folded element, 7-7/16" long:

2000 watt LWD straight element, 10-11/16" long:

Thanks for your advice and patience,

Check this one out? Not sure how long is it?

Thanks, rilewedge. I googled to find the Camco website. That element is 13" long.

Thanks,
