The answer can vary widely based on a home's age and design. As with any type of remodeling project, assume that every structure is load-bearing until confirming otherwise with a structural engineer. Almost all modern homes have chimneys that are fully independent from the rest of the home's framing. As a result, they don't bear any load beyond their own weight. However, many historic homes built prior to the 1900s contain load-bearing chimneys that tie into the surrounding roof and floor joists. If possible, use a home's blueprints or look for chimney connections that indicate load-bearing qualities to get your answer.

There are several ways to determine if your chimney or fireplace damper is open or closed. A simple method is to check for airflow by placing your hand near the fireplace opening; if you feel a draft or hear wind whistling, the damper is open. An open damper might also make the room feel cooler, similar to the outdoor temperature, or cause your HVAC system to work harder than usual. For a more definitive test, you can try a visual inspection, although it may be difficult to see. Alternatively, you can light a small piece of paper and observe the smoke; if it is drawn up the chimney, the damper is open. Always use the damper handle to adjust its position.

This will depend on the size of the pellet stove and how much of the house you’re heating, i.e. just one room or the entire house. Many pellet stoves use anywhere from 80 to 345 watts of electricity per hour. In terms of the pellets, a 40-pound bag can cost $5 to $9. A bag of pellets will burn for about 24 hours.

Some homes with wood-burning fireplaces don't have ash pits due to design choices, construction practices, or the age of the house. Many older abodes don't have them because ash pits weren't a standard feature when they were built. Additionally, in smaller homes or homes with less frequent fireplace use, builders might have opted to forgo an ash pit to reduce costs or simplify maintenance.
