ABSTRACT:
A system, process and coupling device for variably and selectively directing hot exhaust gases of a clothes drier into a heat recovery system wherein the heat recovered is introduced into the return air duct of a home heating system or into a venting system when heat exchange is not desired. A system for use with electric driers is shown wherein the exhaust air is filtered and then released into the return air duct of the home heating system, or vented. A system primarily for use with gas driers is shown wherein the exhaust gases pass in heat exchange relationship with intake air of a home heating system.
