DIY Frequently Asked Questions / How does a tube grate work?


A tube grate functions like a conventional grate or andiron in a fireplace. It is an energy saving device that pulls air into the bottom tube opening, moves it around and over the fire (warming the air as it goes) and then shoots it back into the room. It keeps the room’s air from escaping up the chimney, and when combined with glass doors, is an effective way of increasing the energy efficiency of a fireplace.
