Heating System Types & Technical Parameters​​

​​Boiler-Based Systems​​
​​Power​​: 1.5kW–5kW (residential) / 5kW–15kW (commercial).
​​Voltage​​: 110V/220V single-phase AC or 380V three-phase AC.
​​Material​​:
​​Boiler​​: Food-grade stainless steel 316L (corrosion-resistant) or brass (high thermal conductivity).
​​Heating Element​​: Nickel-chromium (NiCr) alloy (high-temperature oxidation resistance) or PTC ceramic (self-limiting).
​​Temperature Control​​:
PID algorithm with ±1°C accuracy.
Dual thermostats (one for brewing, one for steam).
​​Recovery Time​​: 30–60 seconds (after pulling a shot).
​​Heat Exchanger (HX) Systems​​
​​Power​​: 1.8kW–4kW (residential) / 4kW–12kW (commercial).
​​Material​​:
​​HX Coil​​: Stainless steel 316L (dual-purpose: steam + water heating).
​​Separate Boiler​​: Brass or stainless steel for steam generation.
​​Temperature Stability​​:
PID-controlled brewing circuit (±0.5°C).
Instant steam on demand (no waiting).
​​Efficiency​​: Energy-saving design (no dual boilers), 20% lower energy consumption.
​​PID + Thermoblock Systems​​
​​Power​​: 1.2kW–3kW (compact residential machines).
​​Material​​: Aluminum thermoblock (lightweight, rapid heat transfer).
​​Features​​:
Pre-infusion control via flow meters.
Integrated pressurestats for real-time brewing adjustments.

Core Advantages​​

​​Precision Temperature Control​​
​​PID Algorithms​​: Maintain 92°C–96°C (±0.5°C) for optimal coffee extraction.
​​Separate Brewing/Steam Circuits​​: Prevent temperature fluctuations during milk steaming.
​​Rapid Heat Recovery​​
​​High-Flow Boilers​​: Recover to brewing temperature in <30 seconds (commercial machines).
​​Thermoblock Systems​​: Achieve brewing readiness in 15 seconds (residential).
​​Durability & Safety​​
​​Stainless Steel Boilers​​: Resist scaling and corrosion (ideal for hard water areas).
​​Overheat Protection​​: Automatic shutdown at >120°C (CE/UL certified).
​​Water Level Sensors​​: Prevent dry boiling (IPX7 waterproofing).
​​Versatility​​
​​Steam Wand​​: Generates microfoam for latte art (adjustable steam pressure: 0.5–1.5 bar).
​​Pre-Infusion​​: Gradual water pressure build-up (5–10 bar) for even extraction.
​​Smart Features​​
​​Wi-Fi/Bluetooth Control​​: Adjust settings via smartphone app (e.g., Breville Oracle Touch).
​​Auto-Clean Cycle​​: Descaling reminders and automated flushing.
