A package boiler or packaged boiler is a modern form of steam boiler. They are factory-made to a range of standard designs, according to the size and evaporative capacity required. They are used as both hydronic boilers for heating and as steam generators for small power purposes.
A double boiler is a set of two fitted saucepans or pots that are stacked together with space between them. The bottom saucepan is filled with water, then the second saucepan is stacked on top. The steam from the bottom pot rises and heats the upper pot.
