An Automatic Damper can Save on Electricity, Air Conditioning and Heating Bills
By using an automatic damper you can drastically reduce your heating bill. An automatic damper is all about efficiency. An automatic damper makes sure that either the heat or air conditioning in your HVAC system is being utilized to its full potential.
There is no reason to send airflow into unoccupied areas of a Heating, Ventilation, and Air Conditioning system. In buildings where a gas-fired boiler is installed, an automatic damper reduces the amount of lost heat.
The type of damper that is used in applications of reducing heat loss from boilers and thereby decreasing the residual heat loss from the building through the natural process of convection is referred to as a automatic flue vent damper.
Whenever the boiler or heater is off, the electric motor that powers the automatic damper switches the blade or blades of the damper to the closed position. This insures that you do not lose heat from the boiler. This is because the damper actuator has built in sensory equipment that is tied directly to the boiler and sends signals to the damper on whether to open or close.
So in the instance that a heater is about to be ignited; a signal is sent to the motor of the automatic damper. This allows for combustible gases to flow into the boiler so it can be ignited and begin providing heat to the HVAC system it is attached to.
It is important to note that damper actuators can be either controlled either pneumatically or electronically. It depends on the application of the automatic damper since they have a wide variety of usages. Just because a damper is automatic does not mean that is controlled electronically. A lot of automatic dampers are spring loaded so that when the presence of gases press against the plate/blade the damper automatically opens.
An automatic damper can also be used for airflow control to specific areas of your home known as zones. These dampers are tied into some sort of master controller or your thermostat, and depending on the temperature setting of the thermostat they will either open or close.
These types of automatic dampers are also known as zone dampers. The most common application of a zone damper is to control airflow to specific areas of a home or building. The damper can be set to either open or shut at different times of the day depending on the user's setting.
A zone damper will automatically shut off the airflow to a room or allow air to flow to the room when that particular zone reaches a specific temperature. The whole idea of a zone damper is to regulate temperature so that excess heating or cooling is not lost. This is very similar to the automatic flue damper but just a different application.
An automatic flue damper and an automatic zone damper should not be confused with a an automatic fire damper. Fire dampers are made for galvanized steel and are resistant to oxidation. Automatic fire dampers shut off airflow when the temperature exceeds a certain level to stop the flow of oxygen that is fueling the fire.
