Did anyone do a calculation to measure the electicity cost to run these per month?

If you pay 10 cents per kilowatt hour, one light will cost you 70 cents per year, assuming it is on 24 hours per day, 365 days. If the sensor shuts the light off for any part of the day (month, year), it will be less. You can adjust that amount based on your electricity rates, but this is extremely low wattage and low cost of operation compared to most lighting options.

The device is rated at .8 of a watt. In the worst case, if it runs in a room that stays completely dark 24 hours a day (e.g., never shuts off), for 30.25 days a month it will consume about 6.3 cents of electric power per month, assuming that you pay about 11 cents per kilowatt hour including taxes (as I do). The calculation is .8 watts * 24 hours * 30.25 days / 1000 watts (kilowatt) * .11 (the cost of a kilowatt hour). Your actual cost will probably be something less, because light in the room will shut the light off for some part of the day, and some light in the room will cause the device to dim and thereby also use less power than the .8 watt that it is rated at.

Is this really a concern? Its minimal. About the equivalent of a analog clock except it only is on when motion and lack of light are present.

It uses 0.8 Watts(W) when lit = 0.0008 kiloWatts(kW). There is 720 hours(h) in a month (24hours*30days) so it takes 0.0008kW*720h = 0.576 kWh.Please check your electricity bill to find the actual amount for expense but a 60W incandescent bulb uses 72x more power

I've never done a calculation on it, but these lights can't use more that a few watts per hour due to being LED.If I had to venture a guess, MAYBE $1 a month to run 2 every night. That's probably overestimating.

Good question... we don't have lots of data points yet since the unit has only be running two months at this point... but, it appears our electric utility bill has increased by about 100%. In other words, running the humidifier doubles our electric bill... and increase of $80 per month for our home or about $2.70 per day to run the unit. We are running our humidity at a very high setting.. almost 50% and the unit is wired as 220VAC to help increase the output. Also, this is over a 2,800 sq ft area. We are very pleased with the unit and have heard the same from others in our area. This is our first season with the Aprilaire. We are curious how the canister will hold up over time. We hope this helps answer your question.

Only way to determine that is to 1. Check power bills before and after use or 2. Look at power consumption 1500w and multiply by cost per 1000w (1kw) you pay for electricity. My unit is used to get one room (150sq ft) in my 1700 square ft house really warm and this saves me money.

That depends on your current electric rates. Right now I'm driving close to 40 miles a day and my electric bill had increased by approximately 45 dollars a month. The equivalent gas would cost between 200 and 300 a month

For those who want to know, the cost per day can be figured out by: (watts/1000) * hours * cost per kilowatt-hour. So, if you're using the 4 watt model, 24 hours, with an electric rate of 13 cents per kWH, then it would be: (4/1000)*24*.13 = $0.012 dollars per day. Or in other words, about 37 to 38 cents per month.

It is a very low cost. Electric bill barley moved up last winter. I can't give you an exact figure since that was the first winter here but my son keeps his heat at 65 and uses the duraflame day and night. His bills are about $100.00 per month. He is in a double wide trailer. Far cheaper than oil.

Never thought about it, but it is the only unit that runs full time on that particular bill. The rest is infrequent tool use. Did not notice a change in charges.

Yes. You can manually input your cost per kWh and it will incorporate it into its calculations.

I'm not sure, and wouldn't want to lead you wrong. I know this, I save about $30.00 a month on our electric bill. This unit works great. Household of 2.

Mary, I never figured out the cost of running. Electric rates will vary. I used it winter time only and for 2-3 hours a day. It warmed up the living room, dining room, and kitchen. I didn't notice any change in my electric bill, except that it was lower than when I ran the furnace and heated up the whole place. You can use it with or without the heat, which can be conntrolled with

The panel has been Modified , They are just Solar Panels with standard 2 wires out . I and others modify them and put circuitry and LifePo4 batteries in them and Cut holes for Outlets and usb charging. The cost to do this is around 350 dollars and a lot of time but the results are a Self contained 110 volt ac portable Soln1 .

Please see my answer under the topic "Is it energy efficient?" for an estimate of the maximum monthly heating bill from this unit and how to calculate the cost based on your electric rates and anticipated use.

I can honestly say no. Although I can't put a dollar figure on it, I noticed only a slight increase of my electric bill. It far outweighed turning the heat on, creating another bill. Hope this is helpful.

Not unless you are talking pennies. 8 watts an hour means that at an average 11 cents per kwh, it costs 8x24x30 (wattsxhours in a dayxdays in a month)=5760 watts1000 (watts per kwh= 5.76 kwh x 11 cents = 63 cents per month to run.

I personally didn't notice my electric being any more expensive, but everyone's usage is different. If you run it quite a bit I would expect to see maybe a few dollars extra a month. This is a great heater I would highly recommend it.

Well, since you asked:I would assume a rate of $0.10/kwh So just multiply that times the estimated usage vs an incandescent bulb of equivalent wattage.Have fun with this one!

Definitely not! Our electric company will provide us with a special meter that can plug into ANY device, and it shows you how much energy is being used and at what cost. They should probably look into something like that in their state. But we did not see any significant increase like that. Sorry you are experiencing such an issue, because it really is a great product, and our son and daughter have both benefited from its use. Good luck!
