Annual cost to run 86watt electric compressor?

Anthonyk2010

I'm trying to calculate how much a 86watt compressor that is in my treatment unit costs me.

It's on 24/7 and my electricity costs 17.92 cent per KWH (i think)

by my calculations the compressor is .086kw

Is the hourly rate is it .0047 cent per hour which would make the annual cost about 37 euros.

I'm i right or miles out?

its 86/1000 x your unit costs x 24 x 365 (or for this year 366 as its leap year )

on the kw consumption its normally amps x volts = watts

does the compress - does it not start and stop - it would be unusual to be ruuning 24 x 7

Ya running 24/7, well I have never noticed it turning on and off.

Unit cost is 17.92 cent. By your formula it's working out very high.

I'd be very happy with that.
How did you work it out?

That's most likely because the unit cost you used is 17.92 Cents and hence you need to divide the final answer by 100 to convert that to Euros.

That's how the 135 is arrived at.

Why is it on 24 7? Surly it should just be on demand. What's its purpose?
