950/17.5 = 55. Lets say 5 years break even.
You can probably expect at least 12 years out of it, hopefully a couple years more.
Lets say 15.
So you have 8 years of tank life for $950 = $118.75/yr
If you return it and buy a new one, you're looking at $375 + $800 or so (depends on model, area, install requirements, etc - based on your rate it sounds like a cheaper chimney model. Powervent are typically 1.5x that monthly rate, but also 1.5x the purchase price)
But you'd get a full 15 years, assuming it lasts the same as your current one (which is an assumption even that one lasts 15)
1175/15 = $78/yr
Switch to powervent for 1575/15 = $105/yr
If you're in it for long term, return and buy a new one seems the better choice financially.
