Thanx for the heads up! I'll certainly do some more analysis before diving into a project like that. But it's exciting to know that it's possible to develop your own custom espresso device if you're up for the challenge.
Absolutely! And even if building your own equipment isn't your thing, there are plenty of ready-made stainless steel boiler models on the market that offer quite excellent efficiency and longevity. It all comes down to private preference and what you're looking for in an espresso machine.
