I'm not entirely certain those economisers are legal in every city and town due to CO scares. Id check with your local public safety inspector.

Is this a stupid question?

The flue pipe from the Burnham 396 to the chimney is about 6-7 feet. The cellar (Basement) is kinda cool now that we have insulated all the (one pipe system) pipes. I was wondering if it is possible to rig up some type of fin attachments to the flue pipe to capture more of the heat from the flue pipe. We cannot add a radiator. Should I go back to the funny farm now?

it may look a bit funny, but sure why not? Drop the temp too much and you'll have other problems.

There use to be stack economizers available

Pretty simple little design. Over sized box with say 10" collars on both ends for flue, if 10" flue. Then through the sides were say 10 or so 1.5" steel tubes with fan on one side of tube blowing air through tubes with flue gasses going through box and heating tubes. Only concern is lowering stack temp too much or rusting out tubes. Kinda like the ones you see on some old wood burning stoves.

Flue temp

Take away to much heat and you will have a bigger problem, The flue gasses will condensate before leaving the top of the chimney and you will have acid rain on the inside. and some very strange colors on your roof, not to mention added draft problems....

Pick where you

want the heat. Then remove a section, or two, of your new pipe insulation. No one will tattle.

Save the economizer idea for the industrial guys who know how to make them work.

Thanks, guess the best and cheapest thing is to wear a heavier shirt when I go down there.
