A condensing boiler is essentially the same as a normal fan-flued boiler except that it has a larger heat exchanger, which absorbs more of the heat from the burner and flue gases. Given the right conditions, i.e. when the return water is cool enough to cool the gasses below 54deg C; the flue gases condense and release latent heat back into the boiler, this would otherwise be wasted. The gases coming out of a conventional boiler flue are generally 250-300oC (HOT!) - on a condensing boiler they are around 50-60oC so the potential for savings is obvious.
