Is a high efficiency, condensing gas boiler the best choice

Aug 13, 2018 · 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.

Composite Boilers - Marine Engineering Study Materials

Composite Boilers With diesel machinery the amount of heat carried away by the exhaust gases varies between 20 to 25 per cent of the total heat energy supplied to the engine. Recovery of some of this heat loss to the extent of 30 to 50 percent is possible by means of an exhaust gas boiler or water heater.

Condensing boilers | Jeremias® Exhaust Systems

The high efficiency of the condensing boilers results from the fact that heat produced in the condensation process is used to increase heat supply. The exhaust gasses are cooler and hence the maximum condensing happens in the chimney. The condensate then flows along the internal wall of the pressure-tight pipe, and back to the boiler for disposal.
