How's this setup for a brew kettle heating system look ok to you guys?

Alright. Since propane is outa the question at my new rental house I've been trying to think of a good alternative for boiling in my garage. what i came up with is basically using the design for a heat stick from http://http://hbd.org/pcalinsk/HeatStk3.htm but instead of a 120V 1440Watt heating element on the stick I'd probably opt for a 120v 1650Watt Low-Watt Density element such as http://www.zorotools.com/g/00065662/k-G1741853?utm_source=google_shopping&utm_medium=organic&utm_campaign=Google_Shopping_Feed. Anyone see any flaws with the design or my choice in element? Just needed some input before i ordered. This seems like an okay setup to boil with if i insulate the pot and add marbles to the boil to increase its vigor. Also, I'll be working on a 20amp circuit breaker. Lemmy know what you guys think and thanks again to the HBT community for always being so helpful to me with the working out of the little details! cheers, guys.

I don't know that you'll be able to boil 5 gals with that, but I don't know what the marbles will do. I use two 120v 2000w sticks(on separate circuits) and use propane to help get to a boil and then turn off the gas. I can get a pretty vigorous boil with both sticks and a low boil that is just above a simmer with one. I've also noticed that as the elements get "dirty" toward the end of the boil the boil seems to get less vigorous. I'm not sure if the low density elements would make a difference there or not?
