Is your fireplace damper open or closed??

With summer time just get ready to start thinking about your fireplace is the LAST thing you are doing this time of year.

More likely you’re thinking about grilling, going to the beach and other fun summer stuff so why are we talking about the fireplace again??

Well something we see with too much frequently is the damper is left open after the last fire of the season or, in some cases, left open during entire heating season.

How can you tell if your damper is open or closed and why knowing is important?

in the picture above you see an open masonry chimney damper and the picture below shows it closed.

Just a bit of FYI.. if you home is 2 story and you leave the damper open and don’t have glass doors the flow through the damper, and this is with fireplace at room temp, can be over 500 feet per Minute.  The means all the heated air in your home, especially the lower part, can be dumped outside every 4-5 hrs.

Now if you have glass doors and they are closed that number is much smaller.

Some folks have commented about how the room with the fireplace as always cold or had cold drafts and sure enough they had not checked the damper and it was open.

Now if you have a warm/hot fireplace the number up the flue is higher by a factor of 3.

I tell folks to get the damper closed soon as possible after a fire. With most dampers you can adjust the handle to where it not open as much. This is not true for every fireplace some, especially pre-fab type, the damper is either open or closed.. no middle ground.

Give yours a check to see open or closed it can help save money during winter keeping it closed when not in use.

.. have a good summer and see you in the future.

    Sarah and Will Gilfillan

    Owning and operating Chimney Keepers for 27 years has been a very rewarding experience, and we have enjoyed the relationships we have built with our customers. We are now starting a new chapter and are selling the business to one of our Technicians. Though we will miss the many relationships and friendships we have built over the years, Karen and I are looking forward to traveling full time in our Airstream as we explore the nooks and crannies of North America.

    We would like to take this opportunity to introduce you to Will and Sarah Gilfillan, who will be taking over Chimney Keepers as of March 30, 2020. Rest assured, Will has been well trained (by Carl!) and is very competent, with nearly four years of experience in the gas log/fireplace/ chimney service industry and over ten years as a firefighter. Sarah, the Office Manager/wife is a fast learner, and will do wonders in assisting you with scheduling appointments and answering questions. It was important to us to find a good fit for our customers, and we feel confident that you will find Will and Sarah to be knowledgeable and a pleasure to work with.

    Thank you for your business over the years. It was my distinct pleasure to have been of service to you, and I wish you continued success and prosperity in the years to come.

    Sincerely, Karen and Carl Newton

  • Is Your Wood-burning or Gas-burning Fireplaces ready for Winter?

    Is your Fireplace or Gas Log unit ready to go? If not, or for a service, give us a call.

    During a power outage, a fireplace or gas log unit may be your only form of heat, so make sure they are working in top form. Give us a call to set up an appointment, 919-772-8110.

    PS: If you do NOT have a Carbon Monoxide detector and you have gas logs, GET ONE… NOW… We recommend the combination CO/Smoke, battery-powered, detectors found at Lowe’s, Home Depot, or most hardware stores.

    If yours are over 10 years old, replace them (there’s a date on back). If there is not a date of manufacture on the back, GET rid of it.
