Gas dryer payback
RE "but it is just as stupid if not more so to use an electric clothes dryer if gas is available."
Actually an electric dryer is really not 3 to 4 times as costly compared to gas. At best for pure heating one gains a factor of 3 due to the thermodynamic cycle. In reality here it is at best about 2 since the gas heat flame adds back water vapor; in an area that is basically already a damp swamp. Ie the electric coil adds no water vapor and the gas flame does.
Here with a typical wash load I do the electric dryer if it runs 1/2 hour and on half the time draws 5400 *.25= 1.35 KWHR. My actual measurements are all over the place; about 0.5 to 2; with 1 to 1.5 KWHR being typical as measured numbers with a dial KWHR meter in series. With the 1.35 KWHR number my drying cost is thus 1.35 * 14.5= 19.6 cents.
if I switch to a gas dryer I say 1 dime a load; 25 cents per week; about 13 dollars per year.
if I go to Home Depot and buy the cheapest dryer it is 373 with tax dollars. Figure about 150 for a registered plumber to pull a permit and install a new gas cock by the gas dryer. Now I have 523 in the new gas dryer and I will break even in about 523/13= 40 years.
If I do a jackleg illegal non permited gas connection; the payback is shorter; about 373/13= 29 years
Here I often use the close line during the summer; thus the payback is longer.
the real benefit of using gas here is the gas typically is still one after a hurricane and one has no power; and one can run a gas dryer with little electrical; ie small generator.
Here my house insurance premium factors in not using a gas dryer too; it is tad higher If I get a gas dryer' ie more than the actual 13 dollar gain I save.
The real reason my dad got a electric dryer in 1947 was the apartment building he rented then had electric and no gas for tenents washer and dryers. Later in 1976 the cost of the gas versus electric dryer was really nil; rates were low. The electric dryer was bought like already mentioned; easier on the clothes, less damage. ie one saves the planet by not not going through clothes like mad.
RE "Also while the average American may do 2.5 washes per week the average American washing machine in a primary residence does 6-7 loads weekly. I wonder if they take collectors like you into their skew. ;-) "
The average house in the USA really has not many folks living in them; about 2 to 2.5 per household.
Thus "American washing machine in a primary residence does 6-7 loads weekly." would imply here that 2.25 folks are washing 6.5 baskets of clothes each week. ie 2.9 baskets per person per week. ie each person fills up a basket in 2.4 days. A super model might do that; but not an average Joe.
In this area with the Katrina exodus and population decline; it is often about 1.5 to 2 folks per home. About all have a washer and a dryer.
