Advantages of a Top Sealing Damper

Around this time of year, the cost of the heating bills always spike wildly. No one wants to be cold during the winter, so sacrificing a few extra dollars to kick up the thermostat often seems worth it at the time. Yet when the bills come, a blanket suddenly sounds like a better choice. For those who rely on a fireplace to provide heat for the home, there are some options for cutting costs. One way to save some money is to utilize a top sealing damper.

The damper in the fireplace is a mechanism that controls the flow of air through the chimney. It is generally made of steel or ceramic to stand up to the heat of the fire and it opens and closes with a handle, pull chain or lever. Most fireplaces utilize the damper in order to vent the toxic fumes from the fire. Therefore, the damper should be open while the fire is burning and until the fireplace has cooled once the fire has been extinguished. Any other time, keep the damper closed to keep the warm air inside the house.

One common type of damper is known as the throat damper, which is located just above the firebox at the bottom of the chimney. These install very easily, so they are very commonly found in many homes. The other type, known as the top sealing damper, sits high in the chimney, and is less frequently seen. However, the top sealing damper does have its benefits.

The way these two dampers differ is based on the draft, or how the air flows through the chimney. Warm air rises, so when the fire starts, the warm air moves up through the chimney. This draws out the smoke and other toxic fumes while also pulling fresh, oxygenated air into the fire from the home, creating a steady flow of air. In a throat damper, the chimney is primarily filled with heavy, cold outdoor air, so the hot air moves more slowly up through the chimney at first. If the initial fire is too large, it could end up filling the house with smoke. On the other hand, the top sealing damper allows the chimney to fill with the warm air from the house prior to lighting the fire. Thus, when the fire starts, the hot air and smoke can move quickly up the chimney. This saves time and fuel when first lighting the fire, making the top sealing damper an easy choice.

Oil Furnace Flue Cleaning

With the start of the New Year have come bitterly cold temperatures, especially in the Long Island area. Most have rightfully taken shelter indoors, huddling under blankets with the furnace running on high. In order to keep that furnace functioning at its best, it requires some regular maintenance. Experts recommend having a technician service it yearly, but these service calls do not always include cleaning the flue for oil furnaces. If a flue cleaning is not performed, it is important to have it done anyway, even if that means a separate appointment.

When the furnace runs, the burned oil produces a variety of substances, not the least of which is soot. This soot is black and messy, and it is meant to be expelled out of the furnace through the flue. However, as the soot travels through the flue, it often clings to the interior of the flue. Over time, it builds up and can even close off the air flow through the flue. In turn, the toxic flue gases produced by burning oil are forced back into the unit and sometimes into the house. Breathing in these poisons can lead to long term effects like cancer from soot or short term issues like an irritated respiratory tract from carbon monoxide.

Another issue that arises from soot in the flue is the degradation of the flue lining. The carbon and sulfur mixture in the soot mixes with water vapor produced by the fire to form a highly acidic compound. If the flue lining is exposed to this compound for an extended period, it can cause damage. Ceramic flue tiles show damage by splitting, cracking or spalling, and stainless steel flue lining becomes riddled with holes after being eaten away by the acid. Damaged flue lining, no matter the material, can lead to flue gases leaking into the house or even structural damage to the flue. Fortunately, any issues related to soot in the flue can be avoided by having regular cleanings performed.

Not all of the soot vents from the furnace or clings to the flue lining. What does not ends up falling back into the furnace, sitting on vent. As soot is allowed to build up on the vent, the furnace must work harder to force air through the vent. In general, a clogged vent will cost the homeowner more money. It lowers the efficiency of the furnace, costing more in fuel consumption, and it shortens the life of the appliance, which has a significant replacement cost.

If your oil furnace flue has not been cleaned within the past year, or if it appears to need some extra servicing, contact a flue expert to schedule an appointment. For service in the Suffolk County area, contact Chief Chimney Services, Inc..
