Does anyone here have any success stories where they used a home equity loan as a viable way in which they saved a ton of money on interest payments?

Nope, I have never heard of this.  Maybe somebody has but not me.  It would seem to me, that somehow you will have to pay the interest, unless it is interest free payments that you are talking about.  If that is the case, I would recommend more research if you are considering it because it is a bad idea.

I'm not knowledgeable in this area.

The only plus I could see to using the equity in your house would be if you paid off some debt and could deduct the interest from your income taxes. And I'm not sure if you can do that on a home equity loan.

Sorry I couldn't be of more help.
