1-A) BOILER SIZE? Lets just say that when it comes to steamers, boiler size matters. The larger the boiler, that is the more water it holds the more steam it can produce. Why? Well imagine that you have two containers of water boiling next to each other. One is a small coffee cup of water, the other is a large pot of water. Both are being heated by the same size flame, both are boiling rapidly. Now which one would you think would be putting off more steam every second. Well, the answer is obvious. The large pot of water. More water boiling means more steam bubbles being created every second. More water = more steam. So when picking a steamer consider boiler size. Another more obvious point is that more water means a longer run time between fills.

1-B) BOILER CONSTRUCTION: A boiler should be made of nothing other then stainless steel! aluminum boilers corrode over time and steel rusts. It must be stainless steel. Also, a good boiler will be well insulated and have redundant safety features.

1-C) POWER: A boiler should have nothing less then 1400 watts. Any lower in power and you are going to get poor performance. A good boiler should be 1500 or 1600 watts. This is a safe range. Higher wattage boilers tend to trip breakers more often. A larger water capacity can compensate for lower wattage boiler. A good balance is 3 liters of water and from 1400 to 1600 watts.
