The Gaggia Classic Evo (2023) has an aluminium boiler with coating, while the newer Gaggia Classic E24 (from 2024) is equipped with a brass boiler without coating. The decisive factor is therefore the model designation, not the colour.
Based on manufacturer information and independent reports from the Community: Yes, the Gaggia Classic E24, as currently available in 2025, has a brass boiler
The Gaggia Classic Evo Pro does not have a brass boiler. The boiler has an industrial coating to prevent corrosion and deposits. The group itself is made of brass, surrounded by a stainless steel frame.
The difference between Classic Evo Pro and Classic E24 lies primarily in the boiler material and the thermal performance. The brass in E24 provides a more stable temperature and better vapour performance.

CA. 7 cm. My espresso cups fit perfectly underneath. If you want a larger cup for cappuccino, just under 8 cm will work, but then you mustn't fill it too much as you have to lever the cup in and out. However, there is a 3D pressure with which you can get a lot of space.

In the event of a warranty claim, the machine will be sent to a service centre certified by Gaggia.
Yes, very easy, you can find it online (me via ShadesOfCoffee). I'm a zero when it comes to craftsmanship, but I got it done. I don't know what the warranty will look like, but I assume it will be cancelled.
The Gaggia Classic RI9481/11 does not explicitly require the use of filtered water. However, it is recommended to always use fresh water and not to fill the water tank with stagnant water in order to avoid contamination. The use of filtered water can help to reduce limescale deposits and extend the service life of the machine, but is not mandatory. Unfiltered tap water from the city of Zurich can generally be used as long as it is fresh and changed regularly. Regular descaling and cleaning of the machine is important in any case to maintain its function and flavour.
I haven't noticed anything like this so far. However, I will look closely in future to see if there are any deposits on the coating. Thanks for the tip.
Hello,
The "Classic EVO Black RI9481/14" machine still uses the old boiler. However, it is important to note that improvements have been made to the design and materials, including a new boiler lining for improved durability and performance. That said, it does not feature the boiler upgrades found in more recent models such as the Gaggia Classic Evo Pro, which has introduced significant changes to the heating system and internal design.
Thank you.
The machine with the product ID RI9481/11 is not the E24 version with a brass boiler. The E24 version has specific features such as a brass boiler, which is not mentioned for the RI9481/11.
The water in the Gaggia Classic Evo is heated to a temperature of around 98-99°C, which is suitable for optimum espresso preparation. The brewing group is not the E61, but a special design with a brass group head and a stainless steel filter holder, similar to professional machines.
The Gaggia Classic Evo Pro with product ID RI9481/11 comes with a boiler that has a non-stick coating, rather than a brass boiler. The boiler is made of polished aluminium and has a durable non-stick coating, known as Excelia, instead of the previous anodised surface.
