Flue Gas Heat Exchanger ECO Stand-alone 1/7

The module utilises the heat potential of the gas flow and thus increases the efficiency of the boiler system.

At a glance

  • Stainless steel condensing heat exchanger for increasing the boiler efficiency by up to 7%
  • Fuel savings through utilisation of calorific value and waste heat recovery
  • Easily retrofitted to existing systems



For further reductions in flue gas temperature in hot water boilers, a variety of flue gas heat exchangers are available. The ECO Stand-Alone retrofit models are available without a bypass for heating boilers with gas burner, or with a bypass and flue gas switching valve for hot water boilers with oil/gas dual burner.


Heat exchanger in welded construction for installation downstream of the boiler, with connecting branches for water inlet, water outlet and drainage, and including inspection openings on the flue gas side. In the model with a bypass, the hot flue gases pass through control dampers.

Equipment level

The module comes fully assembled. Lifting lugs, feet or transport rails, a flue gas control valve and the required thermal insulation are all included in the scope of delivery and come fully assembled ex works.
