Abstract
An espresso machine can include a pump, preheating component, low volume boiler, and group head. The pump can provide pressurized water to the preheating component, which can preheat the pressurized water to a first temperature and deliver the preheated water. The low volume boiler can have a heating arrangement, water inlet, internal volume, and water outlet, and can receive the preheated water, heat the preheated water to a second temperature that is equal to or greater than the first temperature, and deliver a portion of the heated water. The group head can couple with a portafilter having espresso grounds therein, receive the portion of heated water from the low volume boiler, and force the portion of heated water through the espresso grounds in the portafilter. The portion of heated water can remain substantially at or within about 1° C. of the second temperature as it exits the group head.
