What is the reason for the total gas production of hand-fired hot water boilers

» Natural Gas Demand NaturalGas.org

An example of this is the popularity of natural gas in the generation of steam. Natural gas fired combined heat and power systems, as well as natural gas fired boilers, can be much more efficient and cost effective than older boilers running on coal and petroleum. This is especially true if evaluated on a total energy efficiency basis.
