Yes, I never think it's a waste of time, I was looking forward to figuring out the miniscule gas I will use to get possibly a years worth of heat. I use my atv to haul the wood out of our bush that's aprox 800yards from the house. I'm guessing around 5 gallons (20 litres) of gas max. To cut and haul the wood. Currently we are experiencing record high gasoline prices of $1.58 per litre for regular octane, high octane (no ethanol) must be around $2.00 per litre and that's what ibrun in all my small engines so maybe 40$ of fuel required......believe it....we are paying $8.00 a gallon here currently.....still super impressive low input/ high savings scenario. The atv was purchased long before the woodstove so I don't consider it part of the cost equation.
I wish you as speedy of recovery as permitted, take your time and enjoy.
