Heating system explained

Main heat source: a boiler

Inside machines like “La Doppia” in the Professional series, there is a Large internal boiler (about 2.5 L).

Boiler function:

• Heats and stores hot water.
• Produces steam for milk frothing.
• Acts as a thermal buffer that keeps the water temperature stable during many brews in a row.

Because the boiler contains a significant amount of hot water, the machine can maintain a stable temperature even when several cups of coffee are brewed consecutively.

Brew head with Heat exchanger

Instead of taking brewing water directly from the boiler, the machine uses a Heat exchanger circuit in the brew head.

The brew group contains:

• a Heat exchanger inside the boiler
• two brass components (“torpedoes”) that form the water channel.

How it works:

• Cold water enters the Heat exchanger channel inside the hot boiler.
• As the water moves through the brass channels, it absorbs heat from the boiler water around it.
• By the time it reaches the brew head, it has the right temperature for espresso extraction.

This design ensures:

• rapid heating of incoming water
• even brewing temperature
• stable extraction even with multiple brews in a row.

Heavy brass brew group for thermal stability

The machines use brew groups made of treated brass.

Why brass is important:

• High thermal mass → retains heat very well.
• Minimizes temperature fluctuations.
• Helps create even crema and stable extraction.

This keeps the brew head temperature stable even when several espressos are brewed quickly one after another.

Thermostat control

The temperature is controlled by a thermostat (often around 93–95 °C) that switches the heating element in the boiler on and off.

This maintains the correct temperature range for:

• espresso extraction
• steam production.

Modular heating per brew group

The professional machines are designed with modular brewing units, where each group uses about 400 W.

Advantages:

• lower energy consumption
• easier service and maintenance
• individual modules can be serviced without stopping the entire machine.

✅ In brief:

• A Large boiler heats the water and produces steam.
• Fresh water passes through a Heat exchanger in the boiler.
• The brass brew head stabilizes the temperature.
• A thermostat keeps the system at the correct brewing temperature.

This is a typical commercial Heat exchanger design for espresso machines, optimized for cafés that brew many drinks in a row.

Step-by-step explanation

1. Water enters the system

Water from the tank is pushed by a vibration pump (~15 bar) towards the brewing system.

2. The Boiler creates the heat

Inside the machine is a Boiler heated by an electric heating element.

The water in the Boiler is kept around 93–95 °C using a thermostat.

This Boiler water is not the same water used to brew the coffee.

3. Heat exchanger inside the Boiler

A tube (Heat exchanger) runs through the hot Boiler water.

Fresh brewing water flows through this tube and absorbs heat from the surrounding Boiler water.

This design ensures:

• even heating
• stable temperature before extraction.

In the Aroma group design:

• the Heat exchanger contains two brass “torpedoes”
• they form the internal water channel inside the Boiler.

4. Brass brew head stabilizes temperature

The heated water reaches the heavy brass brew group, which acts as a thermal buffer.

Brass stores heat very efficiently, which means the brewing temperature remains stable even during several consecutive brews.

5. Espresso extraction

Water at brewing temperature passes through:

• coffee pod / coffee puck
• portafilter

→ and espresso is extracted.

6. Pressure relief

After brewing:

• a solenoid valve opens
• excess water is directed to the drip tray instead of dripping through the coffee.

✅ Brief summary

Pump → Heat exchanger in the Boiler → Brass brew group → Coffee

The Boiler produces the heat, while fresh water is heated indirectly as it passes through the Heat exchanger.
