I'm trying to reducing my winter heating bill with a wood fireplace insert I installed before last winter and I am learning everything for the first time. I live in the town of Colorado Springs Colorado. The forest is a 25 minute drive and I can purchase a permit for $30 and bring down green wood that the forest service has cut down and delimbed. It's ponderosa pine (up to 20" thick) and some pole pine. I have to cut the wood into 13-1/2 inch lengths because that's the max length my small insert will reasonably accept. Last year I piled up about 4 cords at my house. Now a year later I am splitting the wood with a hand swing mauler which works well since most of the wood is dry now except for some large bottom pieces. I'm 43 and fit and I don't mind using the mauler, it's good exercise. Someone told me that instead of paying for a permit and getting the wood from the forest I should do what they do and start a small tree removal business in the summer on the weekends. This way I'll get paid for cutting people's trees down and have all the firewood I need for winter. This sounds really smart and my boy friend and I could make a great team at it. We have a lot of Elm - weed trees in this town where they were heavily promoted by our founding city fathers to turn this desert area into the micro climate it is today, that people need cut down. I think on the chart Elm wood has more heat energy than pine although I think it seems the sap in the pine wood may have some heat content of it's own in the fire. That sounds smart and I've fallen trees before after reading the chain saw manual about making the proper cuts and it went well. But I worry if I did it for winter wood, about a customer's tree falling wrong, on a car or fence or house or power lines, or me falling out of the tree... and I imagine I'd have to get insurance. It could be a real headache... and I wouldn't be removing stumps if the customer wants that. Does anyone have experience doing this or money? Thank-you for any info!
