Faema E61 explained: the thermosyphon group head, mechanical preinfusion, and why E61 clones still thrive. Ernesto Valente’s 1961 Faema E61 replaced the lever arm with a rotary pump at 9 bar and a group that stays hot by circulating boiler water. Sixty years later, Rocket, ECM, Profitec, Lelit, Bezzera, and Quick Mill are still building that same group. In this video: What a thermosyphon (thermosiphon) group head actually does How the E61 preinfusion chamber wets the puck before full pressure 9 bar pump vs the old lever pull Why the E61 espresso machine became the prosumer standard Heat exchanger flush, temperature stability, and the cooling flush routine Why E61 clones thrive: parts, gaskets, service, and a group that outlasted the patent Who should buy an E61 machine, and who should not If you are comparing an E61 group head vs a saturated group, shopping a heat exchanger espresso machine, or trying to understand Faema E61 preinfusion before you buy a clone, start here. https://pullcaffe.com/ https://www.instagram.com/pullcaffeco...   / pull-caffe-coffee-roasters-wood-fired-sour...   #FaemaE61 #E61 #espressoMachine #thermosyphon #homebarista #e61grouphead #prosumerespresso#WoodRoastedCoffee, #WoodFiredCoffee, #SpecialtyCoffee, #PullCaffe, #ArtisanCoffee, #FreshRoastedCoffee, #SmallBatchCoffee, #CoffeeRoaster, #SpecialtyCoffeeBeans, #TasteTheHistory, #WoodRoastedSpecialtyCoffee, #FireRoastedCoffee, #CoffeeInACan, #VacuumSealedCoffee, #PullCaffeCoffee, #BestWoodRoastedCoffee, #WoodFiredCoffeeBeans, #TraditionalWoodRoastedCoffee, #SmallBatchWoodRoasted, #AuthenticWoodRoastedCoffee, #FreshWoodRoastedCoffee, #ArtisanWoodRoastedCoffee, #HistoricWoodRoastedCoffee, #PullCaffeSpecialty, #PremiumCoffee
