Is a brass boiler better than an aluminum one?
The Silvia features a heavy-duty brass boiler. We’ve done our research and discovered that machines with aluminum boilers are more prone to failure. Aluminum expands and contracts with sharp fluctuations in temperature, which can lead to leakage in some cases. Also, aluminum is prone to significant corrosion depending on the ph level of your water. Many people are concerned about drinking hot water that has touched materials like plastic and aluminum. Brass is superior in terms of heat retention and avoids any of these potential pitfalls on aluminum boilers. Be sure to check out the manufacturer’s specifications before choosing an espresso machine. Most machines under $700 have an aluminum boiler.
