I finally picked up a natural gas dryer.
It's going to be my new outside dryer.
My old electric scrap yard find outside dryer has served me well and will be given to a needy good home.

The natural gas dryer is using a consistent 650 volt amps. Remember generators and power inverters only care about volt amps.
So your electrical power consumption is 650 volt amps times how ever long the dryer is ran for. So after 1 hour it will use about 0.65kwh.
That's nearly 1/10 the electrical power you would expect an electrical dryer to use.

From a cost stand point running this dryer will cost about 5 to 10 cents worth of power. An electrical dryer uses up to $1 each cycle. Gas use, if it runs 25,000btus of gas for an hour that's only about 12 cents worth of natural gas, if gas is sold by the 1,000,000btu and 1Mbtu costs $5.
With propane your gas dryer will use between 0.5 and 1 pounds of propane per hour if my assumptions are correct.

From an over all efficiency stand point burning the natural gas for heating at the point of use is up to 3 times the efficiency of turning the gas into electrical power, transmitting it to the point of use for heat.
