The invention provides a complete heating system for large buildings in which waste process gas is circulated around a loop of duct which is above the space to be heated and radiates downwardly in said space. Purging and diluting air supplies into and from the duct are provided, and also separate input means for use when process gas is unavailable or unsuitable.
