It keeps my house warm and my room warm. It keeps my mom,dad,sister warm. It keeps us cool in the summer and in the winter it keeps us hot so we don't freeze.I learned that if they made the gas smell good it wouldn't get your attention. But if they made the gas smell bad it wouldn't get our attention. It smells like rotten eggs. Make sure to turn your thermostat down when you don't need it. If you ever smell a gasy smell tell your mom or dad and tell them to check on the gas tank or tell them to call the gas company right away.
