My old furnace=my new what?

I'm getting a new gas furnace tomorrow.
Shopped hard, found the best price and craftsman put of 5 different companies.
I'm certain I could have installed it myself, but furnace supply places here only sell to licensed hvac contractors.

I noticed removal of the old furnace as part of the service an the invoice.
I don't even pay the disposal fee for tires, so I certainly didn't want you pay for that.

I told them that another company was cheaper and If they would match them, I would scrap the furnace myself.
He said I could keep or not but they would match the price either way.
So I saved 100 dollars and gained a furnace.

The furnace is evidently fine except for the heat exchanger, a part that is covered by warranty
Even with with the part paid for it was gonna cost half as much as a new furnace to have a legit company to repair it,so I'm buying a new one.

What should do with this one?
-repair it and sell it?
-Sell it as is?
-repair it and keep it as a spare?
-repair it, convert it to burn propane, install it at my yarden  greenhouse?
-Scrap it for pennies and parts to make a wood shop dust collector.

Tell me what you think I should do.

Is there really any reason to repair it if you place it in the greenhouse seeing as the by product of combustion is warmth and plant flood? Seems to me it would take up a ton of valuable space as furnaces are quite inefficient for the amount of fuel used. A better option in the regard would be a smaller ventless propane unit with a thermostat.

As far as dust collection for the woodshop goes the actual unit is fairly cheap, it is the plumbing and connections that add up quick. For my step fathers shop  I had found a classified ad from a retiring woodworker for a for the price of a new unit that came with all the plumbing and gates he had acquired over the years.


My two cents is make the warranty claim, get the part in hand then offer them for sale at a discount. If no reasonable offers come in then install the part and offer it for sale as a working unit.

Got a picture? I'm curious....
:D

Here's a photo.
I think I will get the part and offer it up for sale.
More so it can realize its highest use than anything.

Oooh, yeah, that's in too good of shape to abuse.

Are you missing a major piece.  I think there should be a burner manifold to go into the heat exchanger?
