I want to have a single chapter heading centered. The other chapter headings should not be centered.

I tried the following:

\documentclass[12pt]{scrbook}
\usepackage{lipsum} % for filler text

\begin{document}

\begin{center}

\lipsum

\end{center}

\lipsum

\end{document}

There probably is an official way to do this seems to work to \chapter*{\makebox[1.0\linewidth]{single centered heading}}. – Peter Grill Jun 21 '12 at 7:12
You should check Yannis Lazarides' answer to this question: tex.stackexchange.com/a/53034/5872 – henrique Jun 23 '12 at 1:44
@Peter: Thanks, that works even better since it doesn't produce a warning (\centerline is a TeX not a LaTeX command). – red_rain Jun 25 '12 at 7:57

\chapter*{\centerline{single centered heading}}

works only for a single line. For two or more lines use \parbox{\linewidth}{\centering ...}
