Pellet stoves are much more energy efficient than traditional fireplaces, and the pellets they burn create fewer emissions, leaving indoor and outdoor air cleaner. Plus, the biomass pellets are made from recycled materials, making them even more eco-friendly. You can also adjust the temperature of a pellet stove and go about most of your day without needing to tend to it.

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.

When it comes to noise levels, outdoor wood furnaces typically fall within a manageable range that's comparable to other standard heating systems. The noise generated by an outdoor wood furnace is primarily attributed to the operation of the fan and blower components responsible for circulating heated air throughout your home.

These fans and blowers are designed to minimize sound while effectively distributing warmth. While you might notice a subtle hum or airflow noise when they're in operation, it's generally not intrusive or disruptive to your daily activities.

Modern gas fireplaces are relatively efficient and don't burn excessive amounts of gas, especially compared to older models. A gas fireplace might use between 10,000 to 40,000 BTUs per hour; the total amount of gas used depends on the fireplace's size, heat output, and how often it's in use. To help keep your running costs down, consider using a thermostat and turning off the fireplace when not needed to minimize gas consumption
