FAQ's

Customer Questions

What makes a gravity furnace different from forced-air systems?

Are gravity furnaces reliable during power outages?

Hello, thank you for reaching out. Yes, they operate independently of electricity, making them highly dependable (if the blower accessory is installed - it will not work without electricity). If you have additional questions, please feel free to reach out over the phone to our Customer Service line at 1-888-901-5460. Have a great rest of your day.
