Patent damper cuts heat loss in home oil furnaces
Strongsville inventor Shekhar Chakravarti Warren Delancey of Elyria and Michael Haydn of LaGrange patent an automatic air inlet damper for oil furnaces. A flexible shaft coupling closes the inlet when the burner stops, preventing warm air from escaping the chimney and saving homeowners money. The device, driven by centrifugal force, is built from plastic and steel and may reduce heat loss by 14.2 to 5 percent depending on appliance.
