Gravity Octopus Furnace in a 2 family home? Run??

[Brad Fausett]

What can you tell me about buying a home with 2 gravity fed furnaces in working order?   Is this a big concern and a reason to run or are they not that bad to replace when the time comes?

Don't pass it up, if it's a good deal and the furnaces are working. Some will tell you that they are inefficient; however, they use little to no electricity, have few moving parts and the parts are still readily available (and affordable). 

Found all above out by reading what landlords from the Midwest had to say via various blogs. 

Finding a good HVAC person, who knows the octopus and will tell you these things make the difference in having a repair estimated at $900 and $150... Found this out just this month. There was a man who told me that these things are easy enough to repair myself :-)

 I wasn't hearing any of the high estimate mess. Plus, I'd already researched and priced the parts. 

My repair cost on the gravity $150. Another recent repair, on a late model, cost me $375 (thermocouple & thermostat only).
