La San Marco 100E Dual Head Espresso Machine: Full Specs & Features

If you’re running a busy café or just want a serious home setup with commercial-level control, choosing the right dual-head espresso machine is critical. Not all machines built for volume offer the precision needed for high-quality espresso, and few combine ease of maintenance with robust brewing performance. So what makes a dual-boiler espresso machine like the La San Marco 100E stand apart for both pros and serious enthusiasts?

The La San Marco 100E-2GR is a 12L copper-boiler, dual-head, electronically controlled semi-automatic espresso machine designed for simultaneous brewing. It features programmable shot volumes, temperature-adjustable group heads, a professional steam wand, and a layout built for heavy daily use—with up to seven shots brewed at once.

What Is the La San Marco 100E-2GR?

The La San Marco 100E-2GR is a professional-grade, dual-head espresso machine built for commercial environments but equally capable in high-volume home setups. Manufactured by La San Marco—a historic Italian brand—it combines classic design with modern programming and durable materials. Its model designation, 100E-2GR, denotes a twin-group electronic machine with integrated controls for precision brewing.

Key Technical Specifications

The 100E-2GR is built with a solid metal body and measures 515mm (height) × 735mm (width) × 570mm (depth). It’s powered by a 12-litre copper boiler, operating at 400V, 50/60Hz with 3500W of power, drawing from a 220V supply. The machine weighs 60kg and is available in red or grey colour options.

It includes dual independent brewing groups, each equipped with four temperature adjustment settings to accommodate different coffee roast profiles. Other specifications include:

• Electronic programmable water dosage per group (6 preset buttons + 1 manual button)
• Flow rate indicator lights
• Dual pressure gauges (boiler and pump pressure monitoring)
• Built-in flow pump
• Automatic water level control with low-water warning lights
• Boiler auto-refill system
• Pre-infusion and pressurised brewing systems
• Lateral heat exchanger
• Hot water and steam wand with adjustable temperature and flow
• 360° rotatable professional steam tip
• Large cup warming area

Programming & Temperature Control

The La San Marco 100E-2GR brings professional-level customisation to your workflow. Each group head has six programmable buttons to set exact shot volumes, plus a manual override option. This allows baristas to fine-tune the output for different drinks or beans without manually adjusting the pump each time.

Temperature is managed via four adjustable settings per group, letting you match brew temperature to coffee roast level—essential for pulling optimal shots from light to dark roasts. The two separate brewing systems can operate simultaneously, enabling high throughput during peak hours. The built-in flow pump ensures consistent extractions, while dual pressure gauges offer real-time insight into boiler and pump performance.

Steam, Hot Water & Maintenance Features

Coffee shops rely on more than just espresso—so does the 100E-2GR. The steam wand is fully professional, with 360° rotation for precise milk texturing. It also features an adjustable hot water dispenser with independently controllable temperature and volume settings, allowing you to prepare teas or Americanos without compromising steam performance.

Maintenance is simplified with tool-free disassembly of key parts, making internal cleaning and part replacement easier. The large cup warming tray is ideal for keeping servingware at optimal temperature. An automatic water level control system includes a visual indicator to alert you when a refill is needed, reducing downtime.

Why Choose a Dual-Head Machine Like the 100E-2GR?

Dual-head espresso machines are ideal for environments where multiple drinks are needed simultaneously—whether you're serving two espressos back-to-back or handling complex orders with milk drinks and straight shots. The 100E-2GR lets you pull up to seven shots at once, with independent control over each group. That means no waiting between orders and better workflow efficiency during rushes.

Its programmable dosing, temperature tuning, and robust build make it suitable for both commercial cafés and dedicated home enthusiasts who demand café-quality results without compromise.
