    1. Are we there yet? Are we there yet? Please come work for me. Your patience is unbelievable. “what, what=2 watts, not very bright” lol

      1. Hi Stephen,
        This will depend on a few factors like what heat seating it is on for and how long it is on per night. Geneally on full setting a single bed electric blaket uses about 70W per hour. Therefore if you used it 2 hours per night 7 days a week it would add in the region of 30 cent per week to your bill.

    2. No queries here as I am easily able to calculate it based on the table above. Just wanted to say based on the questions you’ve consistently and repeatedly answered, you have the patience of a Saint!! I do not envy you but I suppose as they say “No good deed goes unpunished” I bet you’ll think twice before you decide to offer another free information service 🙂 🙂 🙂

        1. Hi
          Was thinking of buying humidifier for house and laundry. Are they energy efficient at 280watts per hr . Sorry I’m useless .

          1. 280W per hour sounds efficient for a dehumidifier but I guess the litre in take is also something you need to consider. It will probably cost in the region of 10 cent per hour to run based on the current electricity rates.

          1. What plug in heater are most efficient… as I’m thinking of not filling oil tank … thanks

          1. A 150W Halogen Heater? If such a thing exists it would only cost about 3 cent per hour to run. However I suspect it is a 1500W Halogen Heater in which case it costs about 30 cent per hour to run

      1. lol, you are one patient individual, i don’t mean to laugh at your pain but i had a good giggle at some of the questions

      1. I just purchased the unit to measure the energy used by an appliance. We just got the bill for the last 2 months billing period . We are a family of 3 I work nights and my partner works from 5am till 4pm . My daughter leaves gor school and is gone all day . This bill was for 402.00 euro and im absolutely gobsmacked. Every bulb is energy saving . Our showers are power showers we have the oil heating on for 2 hrs every evening. Do you have any tips to reduce the cost .

      2. I have a Meaco Dehumidfyrer which is 270 watt I use it to dry clothes in a small insulated drying room using the laundry setting on the Dehumidifer I’m wondering what would be the cost per hour or it mostly is on for 12 hours at a time I wonder is this much cheaper than a electric clothes dryer thanking u John.

      1. Is there any difference in unit rates cycle if I use the washing machine in morning v/s if I use it in mid night..may be 10 or 11 o clock in the night? Can you please let me know the exact timelines.

    1. How much would it cost to run an oil heater 1500kw for an hour every day for a month? House mates trying to blame high bill on hardly any use of oil heater , went up drastically in 2 months over winter , another person in the house has a heater but denying using it

      1. If it claims to be a 120W cooker you got to assume that is the high setting. This would cost about 2 cent per hour to run. If the low setting is half that (60W) it would cost about 1 cent per hour to run.

  1. How much would a storage heater cost to run?
    It’s not wired to the mains….. It’s plugged into a socket.

  2. Good evening, My electricity supplier charges .1739c per unit excluding PSO levy, standing charge and VAT @ 13.5%. (25cent per unit when included) Does your figure of 20c per unit include PSO levy, standing charge and VAT? Thank you

    1. Anne this article is an independent blog post which was written a number of years ago to provide a very rough estimate of costs for users at time of publication. If the overall cost is 25 cent per kw for you it should be very easy for you to make your necessary calculations.

  3. Hi,

    I am worried about the annual cost of running a B- rated condenser tumble dryer. The annual KWH is 561.

    By my reckoning it’s an additional €35.00 a month but not entirely confident in my calculations.

    Can anyone shed any light on it for me?


  4. Hi,

    Would you have any idea how much a 2kw ariston water heater would cost to run over a 24 hour period on full heat? My first electricity bill for 2 months we’ve used nearly 1700 units in a two bed cottage with all new electrics and we can’t figure out what is using so much.


  5. Hi,
    I have fairy lights with USB, plugged into a Phone Charger, could you tell me how much

  6. Hello, I was wondering if you could tell me how much it would cost to run a 200L chest freezer (annual consumption 222 kwh) per day in Ireland please. Thank you!

  7. Hi

    Would the fan heater and the oil heater not be different prices per hour, even though they’re both 2500w. The fan heater element would be constantly on to heat the air. While the oil heater element turns off and on over the period of the hour?

  8. Hi I have an 800 watt led light that I use for one hour at a time . How much would this cost to run please?

  9. Hi

How much that will cost ? I know there is already an answer on the table. But update would be really appreciated.

  12. A 770 watt projector I use for movies. What is the cost per hour? On the manual it says power consumption :770watts

  13. Hi there, how much would it cost per hour in Ireland for a home projector that’s 770w power consumption?

  14. Hi, I’ve just moved into a rented house that has atc lifestyle heaters in every room. 1500w
    Don’t know anything about them, so wondering how much they’ll cost to run?
    I think I can program each one to come on/off at a certain time if left on standby……
    Any advice would be much appreciated……got to plan for winter bill costs. Thank you

    1. check how much you are paying per kw and multiply by 1.5 to get how much each heater costs to run per hour. If your current rate is 30 cent per hour then each heater costs roughly 45 cent per hour to run.
