The center can opt out of the final two years of his current deal with the two-time defending champions by June 30 to become an unrestricted free agent.
The 30-year-old told ESPN: "I don't want to go anywhere. I like it here. It's Miami. Everybody wants to come here. Yeah.
"I'm serious, but that's for later conversation. I'm going to concentrate on [the playoffs] right now and leave that for later business."
The Heat currently lead their playoff series against the Indiana Pacers 3-2.
