What exactly is a Condensing Boiler?
Condensing boilers are the most energy efficient units on the market today. The combustion process produces gas by-products that include water vapour and carbon dioxide. In a conventional heating system, these by-products are vented out of the house. Condensing systems cool the combustion gases to the point that water condenses and the process releases additional heat that is captured and distributed to the home. Condensing gas boilers are generally 10-15% more efficient than conventional units.
