240V dryers outlawed by city ordinance where I live
I live in an area where virtually all neighborhoods are connected to piped natural gas. It costs roughly four times as much money to dry electrically versus with gas (caveat: this is a high cost area for electric power, some parts of USA have electricity priced at half of California prices). Most domestic dryers are offered in otherwise identical electric and gas models. Typically, the gas version will cost $30-60 more than the electric model, but the cost differential is quickly erased by the much lower cost of natural gas here. Outside of the heating season here (November-March), my gas bill is typically $8-11 per month, covering cooking on a gas range (hob + oven), gas tank water heater, and gas dryer (and gas barbecue on the patio). Half of the bill, about $5, is the "fixed system" cost that the gas company charges for maintaining its physical plant....and only $4-6 is actual gas usage.
Because electric generating capacity here is limited (maxed out), many cities now forbid new homes to have a 240V supply in the laundry area, to encourage people to use gas instead of electricity. If you move in with an electric dryer, your choices are to buy a gas model or rip out the wall to install 240V. Oddly, there is no rule against 240V cooktops and ovens in the kitchen, even though most homes are equipped with gas. Sometimes one sees a gas hob but double built-in electric ovens. I myself have an Frigidaire 30" gas range (five burners plus a large single self clean oven); behind the oven is a gas pipe and a 120V outlet. If I wanted electric cooking, I would have to rip out a wall and run another electric circuit in the wall to provide a 240V outlet. The only 240V outlet I have in the entire house is in the laundry area: the house was built a few years before the no-240V rule was enacted in mid-1990s. Since I have always used gas dryers, that outlet has <span style="text-decoration: underline;">never </span>been used.
As I understand it, our electricity arrives at the electric meter in 240V, but is converted to 120V at the meter. Where a 240V outlet is required, two circuit wires are joined together (in parallel, I would assume) to provide 240V. US 240V are radically different in appearance from continental Europe or UK plugs.
