Is a high efficiency, condensing gas boiler the best

Condensing boilers produce heat by burning natural gas or propane fuel. The word "condensing" refers to the fact that these appliances are able to extract heat from the combustion process so efficiently that the flue gases leaving the boiler are at a much lower temperature than in a conventional boiler. The temperature of these flue gases
