Power Venting an Oil Boiler?

Probably a moot point here, but I'll throw my 2 cents in for the record. I have a Burnham oil fired boiler that vents through a Field Control power vent that is now in its 10th year of operation. Every thing considered I would recommend the set up for a back up, but not for the primary heat source. For the first four years living in the house (new construction completed in 2003) we did not have a wood stove hooked up and just used the oil boiler. With that set up I find that the boiler with the vent is overly noisy, it contributed to an odor problem caused by the house being so tightly constructed. The only operational problems that I have had with it were once I hit the vent with the stream off the snowblower and plugged it and about 3 years ago it stopped working and I discovered the fan had rusted itself to pieces as described above. I was able to buy a replacement fan and motor unit at the local supply house for about $225 and got it back up the same day. Right now we get most of our heat (90%) from the wood stove, but do run the boiler when it gets in the single digits. Hopefully this will be the year that we get a wood fired boiler going and can stop using oil altogether.
Also, in regular operation the heat coming out of the vent will melt snow, so it isn't really a problem that it is close to the ground and mine has not stained the siding...
Good luck!
