I'm a little late to the party here, but I was in your shoes two seasons ago. 1961 boiler, $3000 in oil in the first year. I'm starting season three and have 10 cords out there for $1600. That's almost 3 years worth for half the price of one year with the old boiler. You'll like the wood heat better. On year three we find that we are comfortable throwing on a sweater and a blanket in other parts of the house. But we all like to gather around the stove and watch the fire most of the time. And i'm likely the 100th guy to say, but keep the number of that wood guy you got! I got $220 a cord and was thrilled. $175 is crazy.
