I'm all for taking as much energy as possible at the expense of a little work now and then. Anyway, as my dad used to say, "if you were working, you wouldn't be cold would you?"

When you get too old and beat to work, then it's time to get a
nice sleeping bag to keep you warm on those cold days..

My wife has been having hot flashes for about 8 years now, so she has
no interest in having a back-up sleeping bag.. (I've got mine)!

Anyways, I know very little about chimney draft,
but I think it has to be going up (since hot gas rises) and should be a path of low air resistance..
Low drag. (At least on oil, wood & coal fires)..

Someone told me, as the chimney liner heats up, it induces more draft.
Once the burner goes off, it seems like that hot chimney liner wants to
suck air outdoors from the boiler.. (Cooling it off).

So, they make this gizmo that can be installed in the boiler exhaust,
that cuts off the flow, once the burner has shut down.

But, there is a certain risk inherent in the design..
If it fails to open fully, your house might suffer a smoking up..
And of course everyone might get killed by Carbon monoxide..

Be very careful making mods to chimneys. Consult an expert or two.
