Sorry couldn't help myself...
I had a customer in similar situation on gas. He added a 120,000 BTU hot air Keystoker and was just about able to heat the whole house with 10 tons a year. Went from $600 + gas bills a month to about $100. Most of that $100 bucks was probably for hot water, don't think he has a jacket. Anyhow I figured I'd mention that to give you an idea.
I'm concerned about the output of furnace #1 blowing into furnace #2 and vice versa... Since airflow will follow the path of least resistance...
Just a suggestion because I'm not familiar with ductwork but I'd imagine they must have something similar to a check valve such as they have for water. If not hold that though while I run to the patent office.
Any recommendations out there for a good stoker hot air furnace??
The trouble with that question is you won't find anyone to say what they purchased is junk. That's like asking in a computer forum what's better Windows or Mac?
They are all well built American products and anyone that has one will tell you that regardless of manufacturer. Here's a basic list in no particular order, I may leave someone out:
Keystoker, Harman, AHS, EFM , and last but not least Leisure Line. LeisureLine has a forum below and is a member here you can visit there website here: http://www.leisurelinestoves.com/
One thing I will suggest is make sure you have access to the fuel before considering this endeavor. the farther you get away form Northeastern PA the harder dealers are to come by.
