Condensing boilers achieve a much higher efficiency |
In a gas-fired condensing boiler, the water is heated through the heat of combustion, just as with non-condensing boilers. The resulting flue gases are normally passed into the chimney. As a result, the energy contained in the flue gas is lost. However, condensing technology exploits these gases, which consist to a large extent of hot water
