The heart of a “standard gas boiler” is made of either cast iron or steal, it sits on the floor and ranges in the 85-87% AFUE efficiency.    Conventional cast iron boilers are in the majority of older homes located throughout New England.  Standard gas boilers can run on natural gas, propane, heating oil, and more recently boiler manufactures have introduced models that run on alternative fuels such as, pellets, wood, waste oil, & bio fuels.    It doesn’t matter what fuel source a standard cast iron or steel boiler is running on, they all work the same way.   A pointed stream of heat (fire) is produced within the burn assembly and then directed into the inner walls within the boiler.   These inner cast iron walls of the boiler is where the “heat exchange” takes place,  as the heat from the fire heats up walls of the boiler, the water within them circulating throughout the home or building gets heated- reheated.   There have been countless improvements to cast iron boilers over the last 100 years, some are now made with steel, but all standard boilers that are under 90% (none condensing) essentially work the same as the cast iron boilers from the turn of the century.
