With home-heating costs going through the roof, more folks are replacing inefficient furnaces with high efficiency systems. The Revolution II is Burnham's most efficient gas-fired boiler. After an inital pass through the cast iron boiler, flue gases pass through a secondary surface. Here diamond-shaped transfer pins draw that last measure of heat from exhaust gases.
This cast-iron heat exchanger comes with a limited lifetime warranty.
