Bingo.
Some people enjoy it. Kiddos to them. Nothing personal. Just don't claim something is free when it has monetary value that you are burning up in exchange for heat.
Beyond that, I could careless how you heat or how much you spend.
I know a guy that has an OWB that he feeds 5 cord of "free" wood to a year. All the time trying to tell me how much it saves him.
He has a truck, saw, sitter, and a dump trailer. Real similar setup to mine. Last time we had an argument, it was a point in the year where he was done cutting, has his 10 cords processed and ready to be tossed in the boiler. I had just sold my 5th cord of wood for the year and had $850 to show for it.(wood was $170/cord then)
We both put in equal effort to attain 5 cord. And he is gonna be happy and warm all winter. But rather than dump the 5 cord at my house, I simply dumped it off at others. I take my $850 and give to my electric company to power my geo.
Is he really saving $850? We both cut, processed, hard, and handled the same amount of wood. And that wood, either directly or indirectly is providing all the heat we need for the winter.
