ABSTRACT:
An energy conserving device for the prevention of heat loss resulting from convection currents in water heater systems comprising a housing component adapted for mounting on the water heater system inlet and outlet ports, a mounting component rigidly supported inside the housing component, and at least one seal component rigidly attached to the mounting component. The seal component is formed from a flexible material and extends from the mounting component to the inside surface of the housing component to make sealing contact with the housing component to prevent the flow of water caused by convection currents while allowing the flow of water when water is drawn from the water heater system.
