You'll be given advice by your doctor about how much you should move your leg and when you can put weight on it. It takes around six to eight weeks for a minor fracture to heal. You'll probably need to use crutches or a wheelchair during this time, until it's possible to put weight on the leg again.
Oil furnace cost is roughly $2,500 to $5,000 installed, but similar to gas furnace prices, it's not unheard of to spend $10,000+. The average propane furnace cost is $3,000 to $6,000 installed. Again, though, costs could reach or exceed $10,000. If installing a high-efficiency furnace, it might be necessary to upgrade the chimney at a cost of $500 to $2,000.
Since 1 therm = 1.1 Gallons of Propane, we will take 1.1 gallons of propane times $1.49. This will give us an equivalent to the price per therm. 1.1 * $1.49 = $1.63. We can conclude that, at current market prices (January 1, 2009), natural gas is much cheaper. Currently, $0.80 of natural gas would cost you $1.63 if it was bought in propane.
