Gas-Fired Boilers and Furnaces | Department of Energy

Natural gas supplies depend on having a natural gas distribution system in your area, and areas at the end of the pipeline (such as the Northeast) tend to pay higher prices for natural gas. A number of retrofits are possible for gas-fired furnaces and boilers, but before pursuing any retrofits you should consider the potential added benefits

Boiler modulation - is more better? - HPAC Magazine

Boilers are rated on their thermal efficiency, which is simply the ratio of the chemical energy added to the boiler over the energy added to the boiler water. As more heat is transferred from the hot gas into the boiler water, the thermal efficiencies increase and the exiting (flue) hot gas temperatures decrease.
