steam boiler vent: Heat retrieval question

I will have a lot of heat going up the steam boiler vent, into the chimney. Is there any simple way to extract some of that heat that you know of?

I am thinking of two things, large hose clamps slightly tightened over flashing which has heat grease on it to conduct heat, tightened over the vent. The flashing can be cut and sliced to stick out and radiate out the heat.

Or, a fan that blows over the vent stack when the steam boiler turns on.

Sounds kind of hokey, I know. In every way possible I am trying to be more efficient with my utilities. They are very high in the winter. I have replaced 21 windows with double pane and insulated the attic. etc...

Heat recovery

Someone makes (or at least used to make) a device which included a fan, for exactly that purpose. Wish I could remember the name.
