Condensing boilers

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.

What is a Condensing Gas Boiler? | U.S. Boiler Company

Traditional vs. Condensing Gas Boilers. Traditional gas boilers burn natural gas or propane to heat the water in a home heating system. These boilers are vented to the outside via a chimney flue or vent pipe. Traditional boilers typically operate at higher temperatures, which means that a portion of heat is vented to the outside during the ...

Condensing Boiler - Air Conditioning, Heating and

Condensing boilers can achieve greater efficiencies because they capture more heat from the exhaust gases than a conventional boiler. To do this, a condensing boiler has a larger heat exchange surface to enable it to transfer as much heat as possible from the boiler's burner into usable heat, thereby allowing less heat to escape as exhaust gases.
