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

Chimneys should either be sealed or waterproofed, which is different from sealing off—closing at both ends—a chimney. Waterproofing and sealing are both crucial steps to take to prevent water damage and the chimney leaking inside the house. While waterproofing is more comprehensive, both help safeguard your chimney, extending its life span and preventing expensive repairs. 

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.

You should never block both the top and bottom of your chimney. Proper airflow is essential because the temperature inside the chimney will still fluctuate as your house warms and cools. Moisture can build up without ventilation, leading to dampness in your walls over time. Blocking the top prevents debris and animals from entering, but the chimney still needs air circulation to avoid condensation issues. Allowing the chimney to breathe maintains the health of your home and prevents long-term damage.
