Heating system explained

Main heat source: a boiler that provides stability in professional operation

In machines like the “La Doppia” in the Professional series, there is an internal boiler that acts as the heart of the system. The product information mentions both a storage boiler of 1.5 L and the option of a boiler up to 5 liters, showing that the model is designed for flexibility in professional environments.

Boiler function:

• heats and stores water for stable operation
• produces steam for milk frothing
• acts as a thermal buffer so the temperature stays consistent during repeated brews.

This is a crucial feature in a professional espresso machine for cafés, as the temperature must remain stable even when orders come in quickly and the workflow cannot be interrupted.

Brew head with Heat exchanger for fast and even extraction

Instead of brewing directly from the boiler water, the machine uses a heat exchanger circuit in the brew head. It is a well-proven solution in professional coffee machines and commercial espresso systems where both speed and taste must be consistent.

The brew group contains:

• a heat exchanger placed inside the boiler
• two brass components, so-called “torpedoes,” that form the water channel.

How it works:

• cold fresh water is led into the heat exchanger’s channel inside the heated boiler
• when the water passes through the brass channels, it absorbs heat from the surrounding water
• when it reaches the brew head, it maintains the right temperature for espresso extraction.

This design provides:

• rapid heating of incoming water
• even brewing temperature
• reliable extraction even when many cups are brewed consecutively.

Heavy brass brew group that keeps the temperature where it should be

The machine uses treated brew groups in brass, a material especially valued in professional settings for its high heat retention capacity.

Why brass is important:

• high thermal mass keeps the heat effectively
• temperature fluctuations decrease during service
• the conditions for even crema and stable extraction improve.

In practice, it shows in the cup. The taste becomes more consistent, the workflow calmer, and the ability to serve barista coffee at the same level again and again becomes significantly better.

Thermostat control for the right brewing temperature

The temperature is controlled by a thermostat at 93°, and the description also states a working range around 93–95 °C. This is exactly where espresso normally performs best, balancing sweetness, body, and brightness.

This maintains the correct temperature range for:

• espresso extraction
• steam production.

Modular heating per brew group for easier service

The professional machines in the series are built with modular brew units, where each group uses about 400 W. It is a smart solution for businesses that want to combine reliability with more controlled energy use.

Advantages:

• lower energy consumption per group
• smoother service and easier access
• individual modules can be serviced without necessarily taking the entire system out of operation.

✅ In brief:

• An internal boiler heats the system and produces steam.
• Fresh water passes through a heat exchanger in the boiler before brewing.
• The brass brew head helps maintain stable temperature.
• Thermostat control keeps the brewing system within the correct temperature range.

The result is a typical commercial heat exchanger design for espresso machines, developed for businesses that serve many drinks in a row and require consistent quality in every cup.

Step-by-step explanation

1. Water enters the system

Water from the tank is pushed by a pump at about 15 bar towards the brewing system. The high pressure is essential for creating the dense, fine extraction that professional espresso requires.

2. The boiler generates the heat

Inside the machine is a boiler heated by an electric heating element, providing the heat needed for both brewing and steam.

The water in the boiler is kept around 93–95 °C using thermostat control.

This means that the brewing water is heated indirectly, rather than taken directly from the boiler reserve, which helps provide better control in the cup.

3. Heat exchanger inside the boiler

A tube – the heat exchanger runs through the heated boiler water.

The fresh brewing water passes through this tube and absorbs heat from the surrounding water, making the heating fast and even before extraction.

This design ensures:

• even heating
• stable temperature before brewing starts.

In the Aroma group’s design:

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

4. Brass brew head stabilizes the temperature

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

Brass retains heat very effectively, which means the brewing temperature remains stable even during several consecutive brews. This is a major advantage in environments where you want to serve consistent espresso without each shot requiring manual fine-tuning.

5. Espresso extraction

Water at the correct brewing temperature passes through:

• coffee pod / coffee puck
• portafilter

→ and espresso is extracted with a full body, clear Aroma, and crema that holds well in the cup.

6. Pressure relief

After brewing:

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

✅ Brief summary

Pump → Heat exchanger in the boiler → Brewing group in brass → Coffee

The boiler generates the heat, while fresh water is heated indirectly as it passes through the Heat exchanger. This provides a logical, efficient, and professional brewing process for daily service.

Care instructions

The manufacturer does not provide a separate cleaning or descaling guide for this model, but the Professional series is developed with a focus on easy maintenance. We therefore recommend using the machine according to the manufacturer's instructions, keeping easily accessible parts clean regularly, and consulting Aroma for questions about correct use and ongoing care. This is especially important in professional operation where consistent performance over time is as important as the taste in the cup.
