I will love to help you. → I have never heard of this one, though. - I haven't heard it either. I simply wouldn't use it.
It doesn't make sense to do this with "will" because "will" can be used to present an open possibility. "If I don't have anything else to do, I will love to help you". Using "will love" in this context is strange. Just say, "If I don't have anything else to do, I'll help you". This means, "But I could have something else to do". Therefore, we see how "will" presents an open possibility and "would" gives us a closed possibility.
