How do you calculate CPAP energy costs?

[Steerpike58]

I'm trying to calculate how much of my energy bill is due to my resmed. It's plugged in all the time. Is there a formula folks use?

Get yourself a kill-a-watt device and measure it for a week. Multiply by 52. Should get you a decent estimate for annual electrical consumption. Then you can move on to your refrigerator. Your TV. Etc etc. https://www.amazon.com/P3-P4400-Electri ... 84471&th=1

I second the Kill-a-watt recommendation! Once you have one, You'll never stop measuring things.

They can likely be found at Harbor Freight, or Menards--maybe even the Home Depot.

I don't. I consider it essential, something I'm not going to evaluate whether or not to stop running to save money on electricity, so it could be pulling 1.21GW and it would be fine.

However if you want, install a Kill-a-Watt or similar device.

A kill-a-watt can cost between $28-$40 or so.
It will make you more aware of the cost of running older appliances--
which should be replaced as soon as practical.
It's foolish NOT to have one.
We have 2, so we can test 2 things at once.
The cpap uses so little, it's laughable.
We found out that running our distiller costs under 20 cents a gallon.

In the interest of science I did break out the old Kill-A-Watt. Airsense 10 machine, during the ~7 hours I slept, used about 80 WH total. Humidifier on set to 3 or 4. Comes to less than $6/year at my regular rate. Add on the non-sleeping "vampire" power consumption and I may be approaching $10/year? No heated hose BTW, I imagine that would drain enough to put me in the $15/year zone

Do an Internet search and then sort through the information:
