I've been burning a VC Madison in a ~2000 sqft house with poorly installed R7 insulation since the fall of 2004.
I've had several disappointments with it.
First of all, I need to fill it with wood every few hours and empty the ash drawer every morning. It doesn't do it itself.
Second of all, it overfires. For example, when my wife stuffed it full of very dry silver maple on top of 2" of hot coals when it was below zero outside last week and left air intake 1/2 way open the griddle temperature shot from 300 degrees to 900 degrees while she took a shower. Any other brand wouldn't have done that. Right?
Third, it doesn't always produce the amount of heat I want. The above incident was the only time last week the thing heated most of the house to 70. The rest of the time the furnace (set for 68) would kick on for 5-10 minutes every hour while the stove top was between 500 and 600 degrees. I think a non-VC stove would be able to heat my entire house when the outdoor temperatures are -6 to +10 for days on end and yet not overheat the living room when its 40+ outside. Right?
Fourth, the payback was a long time. With 3-6 loadings of (almost) free wood a day it only cuts the gas bill (hot water, dryer, oven, furnace) in half. At that rate, it took one and a half heating seasons to pay for itself, the connector pipes, and the hearth pad. It took another year to pay for the chainsaw (that I needed anyway) and 30 ton splitter through natural gas savings.
You also can't forget that VCs are ugly. Mine looks like this in flat black paint -

The wife would much prefer one of these in the living room -
Finally, VC has stopped making this stove a couple years ago. They are getting hard to find new so I might not be able to get an identical one to replace it if I needed to. Which I would otherwise do without hesitation.
