Is Your Chimney Adding to Your Heating Bill?

If your heating bills are rising even though you are using your fireplace, your chimney may be to blame. That’s because a drafty fireplace and chimney problems can affect its heating efficiency.

For starters, a traditional wood-burning fireplace is surprisingly inefficient. As much as 90% of the heat goes up the chimney instead of warming your home, according to the U.S. Department of Energy. Fortunately, there are a few things homeowners can do to enjoy the warmth of a cozy fireplace and reduce energy costs too.

Chimney Inspection, Amherst, NHCheck Your Damper

Many homeowners forget to close the damper after the fire is out and end up losing much of the heat from their home up through the chimney.  When the damper is shut, it should form an airtight seal around the flue to prevent heat loss in the firebox. However, they can become warped or corroded, which will affect its ability to seal correctly, allowing air to escape and increase energy costs. Repairing or replacing the damper will help reduce heat loss.

You can also adjust the damper to prevent heat loss during a wood-burning fire. Although the damper must be open when starting the fire, you can partially close it after you have a nice fire going. Closing the damper approximately one-third of the way will help retain more heat in the firebox while allowing the fumes to vent through the chimney.

Consider a Top-Sealing Damper

Typically, the damper is installed in the chimney throat, an area just above the firebox. This location deep inside the chimney allows the cold outside area to cool down the interior walls and flue liner. A top-sealing damper, on the other hand, is mounted on top of the chimney. Since it seals the entire flue, it significantly reduces the loss of heat when the fireplace is not in use. It also does a better job of preventing chimney drafts and keeping small animals, debris, and pests out of the chimney.

Replace Your Flue Liner

Flue liners are necessary to protect your home from the intense heat inside the chimney and fireplace. Clay tile liners are among the most popular due to low cost. However, they are not very effective at absorbing or distributing the heat inside the chimney. It is a contributing factor to heat loss.  They also can crack and split open during high temperatures, requiring more frequent repairs.

Installing a UL-listed stainless-steel flue liner will increase the efficiency of your fireplace. One of the many benefits is that it effectively retains and distributes heat inside the chimney keeping your home warmer for a more extended period. It also requires less maintenance and can be used in masonry chimneys with a wood-burning or gas fireplace.

Chimney Masonry Repair, Amherst, NHRepair Masonry Cracks

The chimney is exposed to freezing rain, snow, and other weather conditions that could cause cracks in the bricks and gaps in the mortar joints. It’s like an open window that allows the cooler external air to mix with the warmer air in the flue, which could result in a substantial loss of heat. Have a Chimney Professional repair any masonry damage as soon as you notice it.

I wanted to give 5 stars but they are very busy which meant I had a good wait for both the inspection/cleaning, then for a quote on repairs and then for the repairs. Their prices seemed a little high to me but I have nothing to compare with as they were highly recommended by someone I trust and other companies had plenty of negatives reviews which kept me from getting additional quotes. I am happy with the work and they promptly returned to fix a mistake that had been made. Chris the inspector, Jennifer in the office, and Alex and his repair crew were all pleasant and took the time to answer all of my questions. Alex and his crew even took their shoes off (it was winter) before entering my house without even being asked! So if you are not in a rush and want to ensure you chimney is as safe as possible then I think you'll be happy with Black Moose.

Excellent I highly recommend Black Moose Chimney and Stove; Kelly and Liam are awesome, they did a great job. Extremely professional, arrived early, went through everything with a fine tooth comb ensuring pellet stove was thoroughly cleaned. They also were respectful of my home, conscientious and cleaned up after themselves. Made sure stove worked prior to leaving and told me to call promptly if anything came up afterward. Will definitely use them again.

We've had Black Moose clean our chimney for a number of years.But recently, we had an emergency situation at our home involving our chimney & oil furnace flue, which was caked full of soot from a malfunctioning furnace. They came & cleaned out both flues in no time, even going up on the roof with snow on it! They cleaned up after their work in the interior rooms where the oil furnace and the woodstove are located. Great work. Reasonable prices. Very nice people. You can't go wrong with Black Moose.

Goods: The technicians know their business, very efficient in cleaning/inspection along with cleaning up after the 'dirty work'.Others: Communications could be more effective. Despite early coordination about scope of work (multiple flues within same chimney) the estimate provided did not reflect this and the final invoice was significantly more than the estimate provided.Quote for follow-on chimney relining was significantly more than that offered by other companies in the area (and far more than neighbors experienced for similar work accomplished by other companies)
