Separating heat from charge in a material is an extremely challenging task since they are transported by the very same carriers, i.e., electrons or holes. In this Letter we show that such separation can reach $100\%$ efficiency in a hybrid superconducting quantum Hall setup, provided that the quantum Hall system is tuned to the integer filling factor. We present microscopic calculations for a three-terminal setup to illustrate our idea.
