Abstract: An espresso machine having a brew water tank and a heating block located within the brew water tank. The heating block is preferably made of a thermally conductive material such as copper and will preferably have a body and thermally conductive vertical members extending vertically from the body within the brew water tank. The heating block will be associated with a heat source which can be an electric heater. The espresso machine may also include a pump head consisting of an input, and output, and an impeller mechanism, positioned within the brew water tank and in contact on at least one side with heated brew water. In addition, the brew water conduit connecting the pump to the brew head will be located substantially within the brew water tank. Thus, temperature loss in the brew water conduit or in the pump head will be minimized. In addition, a second heat source may be operatively associated with the bayonet or portafilter.
