Condensing boilers are more efficient

Condensing boilers are more efficient due to their ability to extract more heat from the flue gases that would normally be purged through the flue system as the gases pass through the heat exchanger, this extra surface latent heat within, which would normally be lost to the atmosphere, is instead released and applied to the system it is this ability to extract as much heat as possible from the gas it burns that gives the condensing boiler an exceptionally high level of operating efficiency.
