How Efficient is a Condensing Boiler? (2021) | GreenMatch
Gas condensing technology at work In contrast to the functionality of constant and low-temperature boilers, the functionality of gas condensing technology does not only consist in the combustion, gasification and release of heat. Between the last two steps, the flue gases also condense. The flue gases contain the condensate
24/03/2021 · The functioning principles of a condensing boiler have been known for one hundred years, but its use has become possible only recently. This is because condensing boiler manufacturers can now make use of technological advances in the field of stainless steel and corrosion-resistant alloy design. But how do condensing boilers work?

The answer lies in the fact that combi and condensing boilers used to be separate technologies. If your boiler is more than 15 years old you likely have either a combi or a condensing boiler. But today all boilers, no matter if they are a combi, system or regular, are condensing boilers.
Systems for condensing boiler technology An optimum gas-air mixing ratio is crucial to the energy yield realized during combustion. The mixing ratio needs to be exactly adjusted to the heating value of the gases being used (e.g. natural gas, LPG or biogas). An additional challenge is the flexibility of heat output.
With a non-condensing heat-only boiler, some heat is wasted in the form of hot gases released from the flue. A condensing boiler captures some of the heat from these gases and uses it to heat water returning from your central heating system. It therefore requires less heat from the burner and is more efficient.
