The main difference between the Philips EP2220/19 and the Philips EP2225/10 Series 2200 is not just the hot water function. Both machines have a classic milk frother, an intuitive touch screen, similar capacity (1.8 l water tank, 275 g bean container) and a ceramic grinding system with 12 setting levels. They both feature the Aroma Extract system for an optimum balance of temperature, flavour and cream, as well as the automatic descaling function and AquaClean filter for up to 5,000 cups without descaling.

The Philips EP2225/10 is often praised for its ease of cleaning (dishwasher-safe parts) and its two-part milk frother system, which can make maintenance easier. The hot water function is not specifically mentioned as an exclusive difference between these two models in the sources available. In short, the difference is not limited to the presence of hot water, but rather to details of ergonomics and maintenance, while retaining very similar technical characteristics.

So it's not clear to me whether the 2200 has the hot water function or not...
