I figured you meant E61 when you said HX but am surprised you consider "the
usual usage of HX" to mean E61. Especially considering the attention to

utilize a Heat Exchanger (HX) for brewing and many Prosumer espresso
machines also utilize an e61 brew group the term HX does not and never has
referred to the E61 group itself.
