It depends on the supply voltage watts = current in amps times the supply voltage
The conversion factor of 1 BTU = 0.293 watts. So, 60,000 * 0.293 watts = 17,580 watts. 17580 watts are required to run a craftsman 60,000 btu propane forced air heater.
That would depend on it`s size or input rating. You can get the input rating off the unit nameplate and divide that # by 2500 and that will tell you how many cubic feet of propane vapor the furnace burns per hour. If you buy propane by the gallon ask your supplier how many cubic feet of vapor a gallon of liquid propane yields and you can figure your answer.
Electric furnaces are rated in Kilowatts. The following formula will let you figure it out. Watts = amps x volts. For eg. a 10 Kw furnace draws 10000 watts. amps = watts/volts. 10000/240 = 41.6 amps. If your furnace differs from this example, just plug in your wattage and you will have your answer.
Need to know what type of furnace, electric, gas, or oil before question can be answered.
the older furnaces would draw 700 watts plus depending on the size of the blower. the newer furnaces with variable speed blowers can draw as little as 100 watts
Propane furnaces are available from plumbing and heating retailers. Many local businesses that offer home repair also have physical stores with home appliances such as heaters and toilets for sale.

I have never heard of a way to do this without changing the whole furnace. Propane furnaces are usually thin steal walled heat exchangers with many burners. Oil Furnaces have a large burner chamber and then a small heat exchanger above it. If there is a way, you will need to change the heat exchanger and all electrical components. It may be cheaper in the end to just change the whole furnace.
