Some people also don't do math well, or fall for sunk cost motivations. For example, they've already spent a bunch of money on equipment. I know someone who justified it to himself by claiming that the heat output in his house during the Winter reduced his heating bill, so the losses weren't as bad.

What was the bottom line or net result in financial terms?

Losing at least a couple hundred dollars a month. Varied based on season.
