What distinguishes a condensing boiler from a traditional boiler?

A condensing boiler is characterized by its ability to achieve higher efficiency by utilizing the latent heat of vaporization from the exhaust gases. This process involves extracting heat from the gases that would otherwise be expelled into the atmosphere, thereby recycling that energy back into the heating system. This allows condensing boilers to operate at efficiency levels often exceeding 90%, which is significantly higher than traditional boilers that only utilize a fraction of the heat generated during combustion.

The design of condensing boilers incorporates a heat exchanger that is able to lower the temperature of the flue gases, causing water vapor to condense. This process not only enhances efficiency but also reduces greenhouse gas emissions, as less fuel is needed to produce the same amount of heat. This increased efficiency is one of the main advantages of condensing boilers, making them a more environmentally friendly and cost-effective option for heating applications.

In essence, the higher efficiency achieved through heat extraction is what distinctly sets condensing boilers apart from traditional ones.
