Anticipating my electricity bill - how to calcalute in watt

[lance]

Hi folks,

I'm trying to anticipate my electricity bill after i start using my 2x36W for my 2feet tank.

How should i calculate? 2x36= 72 Watts (in secs)

is the PUB rating at S$0.006 per watts hour? (can someone confirm this?)

so i need to convert my watts in secs to watts in hours by multiplying with 3600 secs per hour?

so i approximately runs 2600k Watts hour per day, which means S$15.6 a day, and S$468 a month?

this figure frightens me a little. Does anyone chunk up hundreds of dollars on electricty bills for your planted aquaria?

thanks in advance.

Hi, think price of electricity is S$0.15 per kwh.

2 x 36W = 72W x 12 hours/day x 30 days/month x S$0.15/kwh /1000
= S$3.88per month

LoL physics! dats why its so important and also why i'm studying it now.
2x36w=72w
pub rate is around $0.13/1kWh of power
so $0.13 for 10000w per hr.
assuming you use 10hrs a day, that makes
total power =72w
total time = 10h x 30
= 300hrs.
energy used = powerxtime
= 72x300
=21600wh
= 21.6kWh
total amount paid per month = 21.6x0.13
= $2.808
hope that helps.

haha... S$400++ bill vs S$1.30

am i scaring myself in the first place?

how about the others? How much is your electricity bill?

thanks for sharing.

sorry slight mistake on the final result. Should be S$3.88/month

[kaipium]

hah, cardinal tetra, I noticed u removed the /s part from your second line. Was about to say that it should be J/s.....

[Cardinal Tetra]

lol made a mistake... its not 72w per sec but per hr. []

thanks guys. It scared the hell out of me when i first calculated. Haven't included the costs of blasting my air-con yet to cool the tanks.

shame on me for miscalculating.

can anyone quote directly from the electricity bills you received? is anyone paying a lot more since u started planted aquaria? thanks

hardly notice any diff between no fish tanks and fish tanks plus two filters plus 220 W worth of light.

it's air con that sucks the power lah. Since we employ all natural night cooling methodologies (ahem), monthly power bill rarely more than $60+.
