How much a clothes dryer cost to use? Again ......
Our very conventional old style tumble dryer timer runs for some 45
minutes per load. With heater cutting in and out (estimating it's on say 80%?). Heater elements are either 3000 watts or maybe 4500, haven't had this one apart yet, since I got it in exchange for a dozen beer! Our domestic electricity costs a little over 10 cents per k.watt hr. So one load of clothes 45/60 x 0.8 a cost of electricity = 0.75 x 0.8 x 0.12 = 7 cents per load. Occasionally it is necessary to run a 'heavy' load, towels and blankets etc. part of a second run. So maybe that could be say 12 to 15 cents per load. In summer we hang bedclothes and towels on outside lines. |

I'll split the difference on the heating element wattage and call it 3750 watts. If you ran it 1 hr that would be 3.75kwh. But, you only run it 45 minutes. so 45/60 x 3.75 = 2.8125kwh And, it's only on 80% of the 45 minutes. So, .8 x 2.8125khw = 2.25kwh Then 10 cents x 2.25 kwh = 22.5 cents Mike |

I think Mike's right - that should be 45/60 x 0.8 x 0.12 x kW: 3kW works out as 0.75 x 0.8 x 0.12 x 3 = $0.22 4kW works out as 0.75 x 0.8 x 0.12 x 4 = $0.29 .... ours is on off-peak so gets 6c/kWh, but I can't remember the wattage on the heater for ours either (and it normally runs for about an hour for a full load) I don't even know where to begin figuring out how much of that heat is being lost into the house (rather than vent outside) and therefore how much useful work it does for the six months of the year we need to be heating the home anyway. So maybe that could be say 12 to 15 cents per load. In summer we hang bedclothes and towels on outside lines. Yes, same here, when we can be bothered. Sometimes we're lazy and just run the dryer anyway :-) Maybe for the summer I should be painting the thing black and running it outdoors cheers Jules |

It's more like two to four times my original number. Thanks. |

I had done a search not long ago and found the average cost to dry a load of wash was between $0.25 to $0.50 depending on your electricity cost. Ten cents is on the low side and it goes up a little over $0.20 in some areas. |

I have never seen a frontloader in the US for $600. The Consumer Reports top rated best buy, is the Frigidaire, at about $750 US -- a fantastic bargain when compared to the Kenmore (Sears), has their frontloaders at $1,000 and up, up past $1600, which was previously the stratosphere occupied by the likes of Miele, and some other hoity toity brands. I suspect a good part of that is the paint job. LG and Kenmore seem to be clones. The high-end stuff offers steam, and mebbe a few other bells and whistles. Oh yeah, these prices are for the washer alone. The fukn dryers are not far behind in price. goodgawd..... I got my previous Kenmore toploader/dryer together for about $800, near top of the line then -- admittedly a few years ago, but it seems toploaders are still in that ballpark. The US never talks about inflation, or when they do, it seems negligible. They must be basing inflation on some gummint subsidized commodity, giving some bull**** reading. In actuality, prices are thru the g-d roof, yo, thru the roof: Fish at g-d Costco is $30 a packet; cars are $30 K; rent/housing/utilities thru the roof. Some people are paying close to $1/ kWhr, where the state has seen fit to ass**** the public into near-homelessness. Gas here is still $3/gal, for no good reason whatsoever. And our gas subsidizes nothing except Mobil's profits. Parking tickets in NYC are $165 a pop, businesses are routinely raided by multiple agencies, with net fines of $10K minimum, often $50K And $3,000 for Kenmore washer/dryer sets. goodgawd.... -- EA cheers Jules |

The "regular price" is ~$800, but Sears' trick with products like this is that they have a number of almost-identical models with only a feature or two different, and rotate which is on sale, so there's always one at the sale price. These are decent machines, with a capacity similar to a normal top-loader (they look smaller, but you can stuff them full, including comforters and other big items because there's no agitator taking up space). You can certainly spend much more on a huge front-loader with digital everything (which will have quite a bit more capacity than any top loader), but that's not really the right comparison. It's like dishonest "studies" showing that driving a car costs $X more than taking the bus, when they average the cost of all cars, rather than comparing *basic* car transportation. Yes, a Lexus is nice, but a Honda Fit or used '95 Saturn is much closer in cost and *still* offers more comfort and features than the bus. YMMV of course... Josh |

These are decent machines, with a capacity similar to a normal top-loader (they look smaller, but you can stuff them full, including comforters and other big items because there's no agitator taking up space). That's a great price! I stand corrected. I guess since the Wife arm-barred me into that g-d Miele, I wasn't really paying attention to the bargains. Boy, was I ****ed when I saw the check-rated Frigidaire, at less than 1/2 the price of the Miele. I wonder if this is the same machine CR check-rated.... I'll check later. The higher-priced jobbies are at 4.5 cu ft, but this looks like really good bang for the buck. The Miele is well-made, tho, and appears to use almost no water. It weighs about 400#. Which means I paid about $4 per lb. Front loaders ought not be more expensive than top loaders, because mechanically they are intrinsically much much simpler -- basically a multiple-speed motor and a belt -- or not even a belt, if direct drive. I've taken apart the transmission of a Kenmore top loader, and holy ****, it would have made NASA proud.... wow.... You can certainly spend much more on a huge front-loader with digital everything (which will have quite a bit more capacity than any top loader), but that's not really the right comparison. It's like dishonest "studies" showing that driving a car costs $X more than taking the bus, when they average the cost of all cars, rather than comparing *basic* car transportation. Yes, a Lexus is nice, but a Honda Fit or used '95 Saturn is much closer in cost and *still* offers more comfort and features than the bus. YMMV of course... Heh, I have a Honda Fit.... great small car, incredibly roomy, a lot of cargo room with the back seats down (or "up"), about 50 mpg highway. With a battery the size of a Harley battery, that they want $200+ for, but sears has something close for about $60. And I think tires will be about $15 each, when it's time to replace them.... CR likes the Fit much better than any of the other half-cars. Sheeit, sometimes I actually have trouble finding it in a lot. Of course, not nearly as bad as the Dumb Car, tho. goodgawd.... -- EA Josh |

I could get the wattage by timing my power meter after switching off all my other circuits and starting a load in with no heat. After the load dried, I'd run it without heat again and check the wattage again. I'd take the average and multiply it by the time a load ran. The exit air is warmer than the entrance air. Without knowing the volume of air my dryer blows, I can't tell if that adds much to the cost. |

Maybe for you, but I take my total electric bill for last month (extra low despite the colder than normal weather because I was away for over 1 week and I don't heat the whole house even when I am here), $125.74 divided by the total KWH's used, 1540 and get my real price at $0.082/KWH That is the total including any taxes, surcharges no matter how many KWH I use, there is no tiered pricing. So using the formula above, drying one load of wash would only cost me about $0.182 , yes, less than 19 cents/load. Maybe YOU fall for the "initial bull**** low-balled "tier" levels", but that doesn't mean everyone does. |

I wonder if you could use two Kill-a-Watts, on different 120 V legs.... I might try that, cuz I bought one for my BIL. Mine is 15A max also, so that could limit you too. |

FOUR killawatt thingies, then?? googawd, nuthin is simple.... I just checked mine. My meter is stamped 7.2Kh. Before I turned on the dryer, a meter revolution took 62 seconds, for 418 watts. With the empty dryer turning without heat, it was 42 seconds, for 617 watts. So the motor uses about 200 watts empty. Where I live, that's less than 2 cents an hour. Next time I dry a load, I can see what the motor uses with a wet load. With the heat on, I can use an IR thermometer to check the temperature of the galvanized vent pipe, which would probably be near that of the air flowing inside. Then if I can estimate the volume, I can estimate how much that adds to the cost. Suppose it's 5000 liters of air per hour (1.4 liters per second) at 122F. If room temperature is 68F, That would be 192 watts to warm the air. That's about what the motor uses. I wonder how much of the power that goes into the motor ends up heating the air. If I put in a wet load at 20 pounds and take it out at 10 pounds half an hour later, that's 2.85kWh to evaporate the water and perhaps 0.25kWh for the motor and warm exhaust. In this case, 92% of the cost would come from the weight of water, which could be determined by weighing the laundry. |

Don't forget to measure current in both legs of course. Actually, with a clamp-on meter, would you get an accurate rating of 220v current if you clamped around both hot legs but with the direction of the wire in one of the legs reversed 180 degrees -- my thinking is that reversing the wire direction would make both currents appear in phase and hence be additive... |

Sometimes we're lazy and just run the dryer anyway :-) Maybe for the summer I should be painting the thing black and running it outdoors cheers Jules About a quarter is what I calculated a few years ago. My time to hang and remove clothes from a clothes line is worth more than a quarter, I'll stick with the dryer. The re-wash after the occasional bird crap incident or being blown off the line in a wind gust also negates any cost savings. |

As per a previous thread, proly better to divide the electric bill by the total kwhrs, and you will find your kwhr cost is double or triple what the stated rate is. * There you go again. As Tony pointed out to you, just because that's how your electric company pricing is structured, it doesn't meant that it's that way everywhere. Here in the next state over, NJ, my residential rate is fixed at a flat rate per KWH. Here in NY it winds up being triple the stated kWhr rate. So the amount per load in NY could easily be 75c. You can drastically shorten your drying times/costs with a front loader wash machine. Front loaders are a win-win x 10 situation, drastically reducing the costs/consumption of everything involved in washing: *detergent, water, electricity, drying time, wear/tear on clothes (less lint in the dryer), and proly a longer lasting machine due to much simpler mechanisms, drive train. |

Agreed Why they cost so g-d much up front is another story..... Also agreed. ****es me right off. A typical machine at a typical 'big store' in England in around 200 pounds - which is somewhere in the $US 300-350 range. Yet typical prices at similar stores in the US seem to be around $600 (or more). There's no way I'm going to pay nearly double the price* that they charge in other countries. (Canadians - what are the prices like for them there?) * actually, looking at the high end of the market it seems like they typically charge an extra $200-$300 for the privilege of owning a front-loader in the US, regardless of how good or bad the product is. I have never seen a frontloader in the US for $600. The Consumer Reports top rated best buy, is the Frigidaire, at about $750 US -- a fantastic bargain when compared to the Kenmore (Sears), has their frontloaders at $1,000 and up, up past $1600, which was previously the stratosphere occupied by the likes of Miele, and some other hoity toity brands. I suspect a good part of that is the paint job. http://www.sears.com/shc/s/p_10153_12605_02632212000P?vName=Appliances&cName= Washers+%26+Dryers&sName=View+All $492, and a whole bunch more in the category from $500-$600 with varying features. We have the 2002 Kenmore version of this, and it was around $500 then too. The "regular price" is ~$800, but Sears' trick with products like this is that they have a number of almost-identical models with only a feature or two different, and rotate which is on sale, so there's always one at the sale price. These are decent machines, with a capacity similar to a normal top-loader (they look smaller, but you can stuff them full, including comforters and other big items because there's no agitator taking up space). That's a great price! I stand corrected. I guess since the Wife arm-barred me into that g-d Miele, I wasn't really paying attention to the bargains. Boy, was I ****ed when I saw the check-rated Frigidaire, at less than 1/2 the price of the Miele. I wonder if this is the same machine CR check-rated.... I'll check later. The higher-priced jobbies are at 4.5 cu ft, but this looks like really good bang for the buck. The Miele is well-made, tho, and appears to use almost no water. It weighs about 400#. Which means I paid about $4 per lb. It is interesting to compare items in $/lb. My new truck at about $6.75/lb including TTR, is cheaper than a good steak... |

No, you still can't clamp around both wires. This is 220/240 *single phase* -- true, you are using two legs of opposite phase, but the net voltage is still single phase. Iow, there is single phase and three phase, but no two phase -- heh, funny how that works. But the clamp-on is a good idea, because it is esp. accurate on a purely resistive load -- no power factor to worry about. You would, however, have to subtract out the the motor current of one leg, tho. If one hot were reading 20 A, and the other leg were reading 16 A, the total wattage would be: 16 x 240 + 4 x 120 x .8 , where .8 would be a typical (inductive) power factor for motors. Presumably the neutral coming from the dryer would also read that same 4 A, but who knows what's going with grounds, etc. -- EA |

But, you only run it 45 minutes. so 45/60 x 3.75 = 2.8125kwh And, it's only on 80% of the 45 minutes. So, .8 x 2.8125khw = 2.25kwh Then 10 cents x 2.25 kwh = 22.5 cents Mike Sounds right to me. I had done a search not long ago and found the average cost to dry a load of wash was between $0.25 to $0.50 depending on your electricity cost. Ten cents is on the low side and it goes up a little over $0.20 in some areas. Try $1.00, past the initial bull**** low-balled "tier" levels. mebbe 10c for the first 10 kw.... heh. -- EA The tiers here are just the opposite, cost per KWh goes down as usage goes up.

I think the easiest thing would be to put a clamp-on ammeter on it -- which shouldn't be too hard since one typically has easy access to the dryer end of the cord where the wires terminate. Don't forget to measure current in both legs of course. Actually, with a clamp-on meter, would you get an accurate rating of 220v current if you clamped around both hot legs but with the direction of the wire in one of the legs reversed 180 degrees -- my thinking is that reversing the wire direction would make both currents appear in phase and hence be additive...- Hide quoted text - - Show quoted text - IMO I think you would be measuring it twice. the current flows from one end of the 220 volt supply, thorugh the the machine, mainly the heaters, and back through the other 220 volt as a return. Some dryers do have some 110 volt that would unbalnce that a bit but not much. |

How much a clothes dryer cost to use? Again ......

Cost to run dryer I live on the Central Oregon Coast & my electric company says its about27.6 cents per HR our rates are 6.14 cents per kilowatt hr. That's relatively cheap; but does that include ALL the charges. To get ours I divide the total bill (which includes a per account and sales tax charges) by total k.w.hrs. Since we are on an even monthly charge plan, the same every month, adjusted annually, it's accurate. |

There was one common model we used in one of the Gulf states called the Indesit, made IIRC in Italy. It was quickly nicknamed 'THE INDECENT' . Problem was that once you started it you couldn't open the door! It didn't use much water and took ages to rock back and forth and 'do' a wash. Then the problem of drying clothes. Either hanging them up in front of the AC (even that was dusty) or finally installing a large US style 230 volt dryer. The electricity btw, was all 230 volt 50 hertz. |

The TWO ends of the same single phase supply. Which also has a centre tap to provide a zero point for two 120 volt 'legs'. Have lived in a house that had a single neutral and three separate phases each 120 degrees apart! There was a 3 phase main breaker and then three separate sections to the breaker panel. |

It can even vary within the state from utility to utility based on specifics of a generation mix, construction costs for needed expansion or to meet mandated generation mix requirements, or pollution abatement edicts, etc., etc., etc., ... IOW, despite wishes to the contrary there still is no free lunch. -- |
