I have a VF170 in my basement. I will echo the same thing others have said here. It is kind of noisy, but it pumps out a LOT of heat. To go with that it also eats a lot of fuel.
I used almost 8 tons this winter.
Also, nice that the hopper is huge. I can load it up and head out of town for 2 days at a time without issue. It'll be empty when I get back, but the house won't have cooled off enough for the furnace to kick on yet. I just filled up the oil tank this week, burned 207 gallons in 2 years now, for probably 95% hot water and just a little bit a heat.
I have had issues with the auger motor. Replaced it 3 times in 2 years. :-\
For what it's worth I paid $1800 for it 2 years ago.
Good luck!
Cheers,
Jon
