Black Knight Energy, Inc. was started in 1976 by Robert L. Purvis, Jr. After returning from a tour in Vietnam and getting a mechanical engineering degree in the HVAC field a life’s purpose was found.Working as a service man for a local heating company in 1976 a customer had no heat. Problem was a plugged chimney causing carbon monoxide to back up and snuff out pilot light. Chimney was full of soot, pieces of mortar and a bird’s nest. Chimney had to be cleaned and opened up in order to get people heat. An old burlap sack was found, filled with rocks, and a rope tied to one end started the first of literally thousands of chimney sweepings.In 1976 was the beginning of the first energy crisis. Heating oil had climbed from 13 cents a gallon to 50 cents a gallon. Oil heating customers were screaming for relief. In the mid ’70s and early ‘80s was the beginning of the wood heating revival.
