An apparatus for preparing infusions such as coffee in different forms includes a sealed container in which water is heated so that it can be used either as hot water or steam, a water tank and a heating element for heating the contents of the container. Water in the tank can flow into the container through a conduit containing a check valve. Four conduits have outlets at the top of the container. One of them is connected to an infuser and is adapted to transport hot water. Another conduit is adapted to transport steam which may be used for preparing a cappuccino-like drink or for preheating a receptacle. The other two conduits are for removing high pressure steam from inside the container, one of them having an outlet near the bottom of a subtank which is built as a part of the water tank.
