The efficiency of a condensing boiler gets enhanced due to its additional heat exchanger. The energy is accumulated when the water gets heated up by the heat in the exhaust gases as it enters the boiler. It's known as a "Condensing Boiler" because of its capability to re-transform the water vapor, produced due to gas consumption, into liquid. The generation of latent heat of vaporisation due to the condensation of exhaust gases is considered a more essential element of energy. This type is best with gas-fired boilers, as less water is produced in burning oil or solid fuel.

How does the Condensing Boiler work?
Condensing Boiler is an improved version of a traditional domestic water-heating boiler. As against the conventional boilers, this boiler incorporates an extra heat exchanger which enables the hot exhaust gases to pre-heat the water in the boiler system. Another vital feature is that these boilers can as well operate with LPG or oil. But the other side of the story is that it even contributes to global warming since fossil fuels are being used.

Advantages

• More heat is being extracted so it is more efficient.
• Less polluting and cost effective.
• It has long life.
• Available in various sizes.
• Easy to install and operate
