Ideally, your chimney cap should be at least 8 inches above the top of the flue, though it's better if it's even higher. You want it to sit that high because it won't affect the chimney's draft, which pulls the smoke up and out of your chimney and away from your home.

Running a gas fireplace costs approximately $0.35 per hour for natural gas and $0.62 per hour for propane, though these figures can vary significantly based on fuel prices in your area. On average, the annual cost to run a gas fireplace is between $400 and $640. The exact impact on your utility bill depends on several factors, including how often you use it, the size of the room you're heating, and the fireplace's BTU rating. Some models with a constantly running pilot light will consume a minimal amount of energy even when off, although many modern fireplaces do not require one. If you are looking for a more energy-efficient option, consider an electric fireplace.

The best location for a wood stove depends on your home's layout and venting options. For optimal heat distribution, a central location on the ground floor, such as the living room, is often recommended. If you have an existing, functional chimney, installing the stove there can simplify the venting process. Alternatively, placing the stove near an outside wall can make it easier to route a new chimney through the roof. For safety, ensure no combustible materials are near the stove. Building codes typically require 20 to 36 inches of clearance between the stove and any side walls.

A quality pellet stove that receives proper maintenance can last between 15 and 20 years, while most will last at least 10 years. The exact lifespan depends on factors like frequency of use and how well the stove is cared for. Proper maintenance—such as periodically cleaning the vents, vacuuming the ash pan, and refreshing the pellets as needed—can significantly extend its life, making it a worthwhile long-term investment.
