An atmosphere controlled workplace heating chamber (10) includes a spaced apart multiple gas flow means combination (22, 24) which avoids contamination of the atmosphere within the chamber (10) from ambient atmosphere such as air. In one form, the chamber (10) includes a gas diffuser (22) as one flow means, and a heating means (38), both of which are readily removable, and easily and accurately replaceable.
