Function
Motor-driven flue gas dampers can be used for all oil and gas fireplaces with or without a fan, as well as for solid fuel fireplaces.
In contrast to the thermal Diermayer damper, it already opens before the burner is started up or optimises the combustion of solid fuel stoves in conjunction with the stove control. During periods when the fireplace is not in use, it closes the flue gas path and prevents heated room air from escaping and the fireplace from cooling down.
The motor-driven version can be controlled in different variations: e.g. manual control via a power switch or temperature-dependent control via an upstream thermostat.
Saving energy with the motor-driven flue gas damper
Motor-driven flue gas dampers can save up to 4,000 kWh per year or more, depending on the system.
The payback period is somewhat longer than for thermal flue gas dampers. Due to their high life expectancy, they are always a profitable investment. As a result of the lower fuel consumption, the flue gas damper also reduces emissions, which is reason enough for many to decide to install this component.
Safety with cascade systems
More and more frequently, multi-occupied systems are operated in positive pressure on the flue gas side. To prevent flue gas from flowing back through switched-off units, backflow protection devices are mandatory. Tightly closing motor-driven flue gas dampers in accordance with DVGW worksheet G 635 are the ideal option for this task to ensure a high level of operational safety.
