A heating apparatus and method of heating. The embodiments of the invention relate to coffee machine heating apparatuses for providing heated brew water for passing through coffee grounds. The apparatus and method involves using low pressure steam (i.e. less than 1 bar absolute) at a saturation temperature that is substantially equal to the desired brew water temperature. Advantageously, improved temperature control of the brew water is achieved in a manner which is more convenient to an end user. The operating temperatures are more stable (the need for a “cooling flush” is removed) and the operating temperatures is reached in a quicker manner than with conventional machines.

A multiple tank heated water system and method for use with a beverage making apparatus. The system includes at least two individual water tanks for controllable heating water. A first tank of the multiple tanks including an inlet port receiving water from a water source for controllably heating water. A second tank communicating with the first tank to receive heated water from the first tank for controllably heating in the second tank. A control system operatively associated with the heated water system. A thermostat connected to each of the multiple tanks for detecting the temperature of the water within the tank, each thermostat communicating with the control system. A heating element associated with each tank, each heating element communicating with the control system.

A device for preparing hot beverages (1) has a flow control system (2) with a water source; (14) a brewing unit (40) with a brewing chamber (41) to hold brewing material and an with inlet line (L4) for the inlet of brewing water into the brewing chamber (41); a heating device (9) for heating the water supplied to the brewing chamber (41); a pump (9) configured to pump the water from the water source (14) to the brewing chamber (41); and a control device (18) to activate and deactivate the functional components for preparing of a selected beverage. In order to obtain an optimum brewing result, the control device (18) is configured to activate the pump (9) at a preselected rate of flow from a selection of different rates of flow ({dot over (V)}) for a subsequent beverage preparation.
