These heat exchangers can also be used as a stand alone heat source by simply attaching a fan or squirrel cage to one side of the unit. They can be installed in either the hot air side or the cold air return of a furnace. Please note that if installed in the cold air return you will need to install a 3 way zone valve in order for the fan to operate properly. We provide a limited lifetime warranty against manufacturer's defects.
