Marpac: Cost effective solution? Hi guys, I was wondering, does anyone know how much electricity the Marpac uses?

The model #980A draws about 38 Watts or .31 Amps (1/3 of one ampere) or less than a 40W light bulb. The model #980A requires very little power and is very cost effective for its intended uses.

Do lots more research before making any purchase. You saying 750KWH/month says to me (750 / 30) 25KWh/day. If that were solar panels, that would be about 12,500 Watts of solar panels in a 2 sun/hour day area. Somehow I expect you mean something else, tho some homes use that.

I used a Killawatt unit to measure my new ADR30A2G. With the fan speed on low it uses 276 watts. It was also drawing 2.59 amps and after 4 hours it used 1.07 kwh. Where I live that cost me around 8 cents, or 2 cents an hour, or a half a buck per day.

I don't have an exact time. So far I've been experimenting with various speeds to see what works best. It just seemed that when I ran it on the top speed it was eating up power. I'll try a more rigorous test during the week and try to post it here.

For my house (1400 sqfeet, in maryland), we typically use ~100 galon per month. We are using this for main heater of my house. Still a bit cheaper than electric central heating cost.

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.

Thanks Gourd! That was very helpful information!! And thanks Randy, as I haven't even thought about this! I am in FLorida and will look into what (if anything) Progress energy offers for rebates! It seems to be that the powers that be over there in CA are generally "greener" than us over here in Florida- but I can hope and find out! Thanks you two!

I have three of these things and they currently make me about $1 per day. Subtract the electricity cost and I might make a penny or two per day. Despite not really making money with them anymore I will use them over the next couple of months since they will make great heaters for this winter.

I've had a Marpac for about 10 years. During that time I have found it very reliable and easy to set up so that it gives the kind of smooth white/fan noise that I like. I have it down on the floor next to my bed and use it on the low setting with the holes on top open and the opening on the side about 1/4" from the top of it's diagonal slot. The wattage on the label is listed as <12 watts, so on the low setting I think its draws about 6-8 watts. (I base that on the fact that on my pillow the two sound levels differ by about 3db using the C (wider range) setting on my sound meter.)

it's a great price but has anyone used it for years all through the night? One answer suggested it wore out quickly. Perhaps a more expensive choice like Marpac might last longer? anyone have experience with both?(THIS IS A QUESTION; NOT AN ANSWER.)

That is the issue. If you want really long endurance off the grid you need to consider inverters, charge controllers and deep cycle batteries. All these cost a bit more and occupy more space. I've used this APC unit for 3 years with my database server and it has worked flawlessly. It is big and heavy for a UPS, but it keeps up my sever for about 2 hours when new. Monitor is off and the other equipment is run from a separate UPS.

I agree with David Banker. Your most expensive part of setting up any wind, solar, or other green energy project will be your infrastructure. Batteries, wire, charge controllers, converters, fuses, brackets, screws and paint. You will have $2,000 into your project. This is a lot of money and time to put into a project like this. But it pays for itself each year when I loose power for four to eighteen days. I set mine up for just a freezer and I had to add another 300 Watt panels due to the winter solstice. And I live in Nor Cal.

If you have to ask, then you cannot afford it. I suggest a Sun Dial, it uses on volts, watts or amps.

I used a kill-a-watt to measure how much power is used. I'm assuming a worst case scenario of 24hrs a day operation and a power cost of 10 cents per kwh.In the fan high mode, the unit uses 65watts. 65watts x 24hrs=1560 watts /1000= 1.56kwh x .10= 15.6 cents per day1.56kwh x 30=46.8kwh x .10= $4.68 per month46.8kwh x 12=561.6kwh x .10= $56.16 per yearKeep in mind that your unit will probably never run anywhere near 24hrs a day so cost will be lower. Mine ran non-stop for 2-3 days and now it cycles on and off on low to easily maintain 40% humidity for 2100 sqft. For those interested, the unit draws 55 watts on medium, and 45 watts on low.

UHM Are you sure you need that much power in 1 month? I use 300kWh at most at my house. Assuming you mean average over a year and not 2,400kWh worse case, you would need around a 25kW array. This also assumes the system is facing south and not obstructed by trees. This is a large system and you would need 174 panels. Typically a residence has around a 5kW array so yours would be 5 times larger.

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.

You use alot less power.I have a 1000, 600, 400 and my bill went up only 50$ a month versis old school ballast it would b 150$ more a month
