Are passive flue gas heat recovery devices savers?

Normally, flue gases escaping to the atmosphere can exceed 60°C. Passive Flue Gas Heat Recovery Devices reclaim much of this wasted heat, letting the flue gases then vent to the atmosphere much cooler. A heat exchanger is fitted around the flue coming from the boiler to heat up mains cold water that is fed into it.
