Gas and electric heating system

Abstract

The gas and electric heating system has combination gas and electric heat generators to provide energy to a steam-generating boiler. The system has a blue-flame, gaseous-fuel burner disposed externally to provide heat to a steam-generating boiler and electrical heating elements that are positioned inside the boiler. Steam generated in the boiler flows to a heating core. The core is positioned in an air duct. Heat is transferred from the core to air flowing through the duct. The heated air flows from the duct into an area to be heated. Controls are provided to correlate the functions of the various components in the system.
