    Cost to Run Tumble dryer

    Cost to Run Tumble dryer 21st Dec 06 at 10:29 AM
    Can anyone help? I live with two Cocks, well they are humans, but only just. Anyway, They refuse to turn the heating up to 20C as they say they cant afford it as its too expensive to turn the heating up that high. Ive explained that that is room temperature but they are idiots.

    We have a condensing tumble dyerwhich they use for at least an hour everyday and i wa wondering if there were any facts i could show them to prove that the tumble dryer is more expensive then the heating.

    Please help.

    To work out the running cost of your tumble dryer or any other electrical item, first you need to look at your leccy bill and find out what you are being charged per/kilowat/hour. Then you need to find out the wattage rating for the appliance.
    So talking in round figuers, if your charge rate is 10p per kilowat/hour, and you run something rated at 1000w(1KW) for 1 hour, it will cost you 10p plus VAT maybe ?
    Hope my explanation is understandable.

    I have no idea about kw and stuff, i just want to have a rough figure to show my !!!!!!!s of housmates that having the heating on 20c is far cheaper then them using the stupid, loud tumble dryers.

    Almost impossible to calculate as it will depend on the heating losses in your house.

    Also, you don't say what temperature you would otherwise keep your house at?

    But based on my fag-packet calculations, I reckon it costs an average of !!!163;3 per day to heat my house, probably to about 20-21C. (Based upon yearly costs [less 10% for hot water] spread over five months. The differential cost of dropping 1 deg C is usually quoted as being about 10% so in the region of 30p per day.

    So depending on what temperature you keep your house at normally, it's cheaper to use the tumble drier.

    Millions of caveats to this, though

    I keep the house at 20c but they moan that they cant afford to turn the heating up that high, my argument is that the tumble dryer is much more expensive then heating and they use that all the time. Id say they have it on for an hour or so twice a week at least.

    Yes, but this doesn't make sense. If I get you right, you're saying that you want to keep the house at 20C, they want to keep it at, e.g. 18C.

    Your argument is that by having the house hotter you could dry clothes quick enough that you would not need to ever use the tumble drier. If that's the only reason you turn the heating up, then it's clearly wrong: it's far cheaper to use the tumble drier for an hour twice a week than to have the temperature higher whenever you have the heating on.

    Plus, unless you have the clothes on radiator airers, so they're not draped on top of the actual radiators, the boiler will have to work harder to maintain the same heat output.

    Sorry, but would suggest you pop into Aldi/Lidl and see if they've got any of their thermal undies left, and see if you can reach a compromise with your flatmates.

    Many years ago when I was at university I shared a house with 4 others. The house had a coal fire but we couldn't afford coal. We had to sneak out at night to "borrow" wood wherever we could find it. The room would eventually reach a temperature high enough to melt the frost on the windows. There was no heating in the bedrooms so we would warm them (sparingly) with electric heaters before going to bed fully dressed.

    I get the impression that life is easier for students nowadays.

    I have no idea about kw and stuff
    Oh, dear. Well just remember that knowledge is power. Without even a basic understanding of "kw and stuff" you may struggle and you certainly won't sound convincing.

    A condensing tumble dryer is an electric heater and all the heat is lost into the house instead of through a vent pipe. If this does not heat your house enough then of course it will cost more to heat it than one tumble dryer alone. I think u'd need a tumble dryer continueously running in each room to heat the house. If they are big cocks then you could eat them instead of buying a turkey!

    Three years ago when we were renting a flat my landlord didnt want us to steam up the property by drying clothes inside so he he put a tumble dryer in the garage rigged up to an old electricity meter. It used to take 7 units to dry a full load (about 3p per unit at the time) so about 21pence per load. Not too sure what you are being charged per unit but to take into account energy price rises you could probably double that. Now we have our own (well the Banks) house we try to line dry as much as possible But if it is wet we tend to use the dryer - much preferableto the house being fogged up with drying clothes.

    Kieran, the cost of running a TD for a few hours a week is negligible compared to the costs of heating a whole flat.

    Plus, as Andrew correctly posts above, most if not all of the energy used by a condensing TD heats up the flat anyway so in fact the real cost of running it is fairly close to zero in winter.

    This would not be true if it was a vented dryer as then most of the heat disappears outside through the vent.

    20C is not necessarily room temperature. Some people consider 16 !!!8211;18C to be room temperature.

    Wear thermals and keep active indoors and you will be fine.

    I was just about to ban my tumble dryer after getting my latest leccy bill...after readng this I think I'll look for culprits elsewhere instead!

    I wonder what gadgets the kids have left plugged in...?

    A typical tumble drier would cost about 24p/hour to run. Similar to a typical electric heater.

    Increasing your room temperature from 18C to 20C would add about 20% to your annual heating bill. You can estimate your own costs from:

    I often come downstairs in the morning (im first up) and the kitchen light is on, lamp in lounge is on, tv is on (not standby, just ON), leccy effect fire will be on, power to the shed will be on...

    Then wonders why we have high bills...
  • keelykat
    Hi, we use a washer drier, and our bill isnt that big for using the drier. I'd look at all the things you use electricity wise as sometimes its easy to forget that certain appliances use up more then you realise. I made the mistake of leaving our hot water switched on all day and night, and ran up a big bill just by doing that! we dont have gas by the way, so dont have the usual boiler. we have to be carefull with our storage heaters too-think ive got it sussed now so that things are running smoothly without getting a huge bill!


    ps-i got a bad problem with damp on our walls after hanging up wet washing-so the tumble drier has been a god send, and now after sorting out the damp and redecorating, weve got no more problems with steamed up windows and damp walls!

    Resurrecting this thread because I've been scared into stopping using my tumble drier (venting to outside) because of stories of how expensive it is, so went out and bought an airer.. Then yesterday I read in that driers can add up to 48 per year to your fuel bill. Hmmmm - I thought, then that's less than 1 a week for the drier - could be even less for us because there's only DH and I in the house and I only use the drier 3, max 4 hours a week. So - do you think that figure is correct? Because having wet washing around in the bathroom, and the towels less fluffly just doesn't seem worth it despite the scare stories!

    Any guidance appreciated.

    Impossible to say without knowing a) your drier's power rating b) your electricity cost per kilowatt.
    But typical drier uses 3.5kw, say 10p per kw, so 35p per hour x 4 hours = 1.40 per week or 72.80 p.a. Or on 3 hours a week, 95p a week or 54.60 a year.
    So 48 is probably a bit under.

    As a general reply to the several threads about "How much does it cost to run ....", it's very simple to work out - as mentioned earlier in this thread.

    Check your bill for the price per KiloWatt Hour ( KWh). If it's 10p, then it costs 10p to run a 1KW appliance for 1 hour.

    Check your appliance for it's energy consumption - this will be either in the instruction manual or on a sticker on the appliance. Just be a bit careful with things like microwaves - you need to check it's consumption ( i.e. INPUT ) rather than it's output rating.

    Multiply one by the other. So if your iron is 2.5 KW, that's 2.5 ( consumption ) * 10p ( rate per KWh ) = 25p per hour ( OK, slightly less because it won't be "on" for the whole time, it clicks on and off to maintain the temperature ), but it's near enough. Things like tumble driers and lightbulbs are easy because they're either on or off.

    For light bulbs, remember 1 Kw = 1000 watts. So a 100w lightbulb = 0.1 Kw, a 40w bulb = 0.04 Kw. So for instance, a light fitting with 5 * 40w bulbs in it is 5*40 = 200 watts, which is 0.2 KW.

    Hope this helps.
