The invention provides a heating device comprising a base structure comprising a fluid channel and a heating element, the heating element arranged in use to heat fluid within the fluid channel, the heating device further comprising a cooling means, arranged in use to cool the fluid channel.

Heating devices and apparatus

An assembly for frothing a fluid having an air channel with a controllable air valve and having a fluid channel with an air inlet emanation point in which the air channel emanates, a pump, a fluid restriction, a heater, and a valve assembly having a first state in which fluid is channeled to a fluid outlet of the fluid channel and a second state in which the fluid is diverted from the fluid channel to a second fluid outlet. A water supply channel is connected to the fluid channel. The assembly also includes a cleaning reservoir and a return channel that is connected to the second fluid outlet of the valve assembly and that emanates in the cleaning reservoir. An electronic controller assembly is configured to control at least the pump, the heater, and the valve assembly, and to operate the assembly in a production mode and a cleaning mode.

Assembly and method for frothing fluid

An assembly for frothing milk, including an air supply assembly including an air channel having an air inlet and a downstream end. The assembly also includes a fluid channel extending from a fluid inlet to a fluid outlet. The fluid channel subsequently includes an air inlet emanation point to which the downstream end of the air channel is connected, a frothing unit including a pump and a flow-through heating unit. The flow-through heating unit bounds a heating unit fluid channel that is a part of the fluid channel and has a small thermal mass and a steep temperature profile.
