How low is consider low power consumption?

[totoro17]

Hi,

Is 150watt low for chiller? How much ur electrical bill you have spend for your reef?

Best regards,

Darren

y no pple reply? 150watts consumption is it high or low for chiller?

Well, that will depend on how long is your 150W chiller works.

If your 150W chiller works 24/7. Then base on calculation

24 x 7 x 150 = 25.2Kw per day.

25.2Kw x 30 x 0.2102 = $158.92 per month

Compare a 400W chiller that works 8hrs a day

8 x 7 x 400 = 22.4Kw per day

22.4Kw x 30 x 0.2102 = $141.25 per month

Then, I would rather take the 400W chiller as in the long run, I save on the $. Unless, you are talking abt Arctica or Daeil Chiller which is low power consumption but efficient. But then initial price will be a killer.

how come ur calculation so weird bro? 100odd bucks for chiller? mine is only 30odd la..

650w x 8hrs x 30 days x 0.2102 / 1000 = $32.79

[totoro17]

im thinking of buying frm another forumer here his haier chiller for $80 but nw raising $$ for it...

normally chiller is on 24/7 or can i on it during the day time only??? will it spoil the chiller? how much top up gas? wats other thing i nid to take note when im maintaining the chiller?

so which is correct? $100+ for a chiller damn expensive....i cun afford...can anyone pls clarify? thx a million

[hondaker]

i think the calculation for neokn is a bit off

the first eq, he mentioned wattage per day

but actually he multiplied by 7, so it should be per week instead

so the final figure should be divided by 7 to obtain the correct results

**EDIT**

24x30x150W=108kW per month

monthly bill = 108kW X 0.2102 / 1000 = $22.70

i do not have chiller, but from the reports seen on the forums, the chiller is rated based on their kick in timing vs idle timing.

so over a 24 hour period, if it kicks in 1 min every 3 mins, means 8 hours of operation per day

and using the above mentioned formulas, u get the monthly bills

Sorry, some calculation went wrong here.

If your 150W chiller works 24/7. Then base on calculation

24 x 7 x 150 = 25.2Kw per day.

25.2Kw x 4 x 0.2102 = $100.80 per month

Compare a 400W chiller that works 8hrs a day

8 x 7 x 400 = 22.4Kw per day

22.4Kw x 4 x 0.2102 = $89.60 per month

huh? cfm or not?

[neokn]

huh? cfm or not?

Coz I use 4 wks to represent 1 month mah.

[Qxnviolet]

I think the respective power usage of 25.2 KW and 22.4 KW is for the week....not day?

[w3ish3ng]

my total increase only 70bucks leh, including all my eq leh. haha ur caculation got problem?

If your 150W chiller works 24/7. Then base on calculation

24hrs x 0.150KW = 3.6Kw per day. (You didn't convert the 150W to KW)

3.6Kw x 30 x 0.2102 = $22.7016 per month

Do the math for 400W yourself

Erm, anyone has any idea how many Watts of power does a CL450 consume?

Your calculation is wrong la... Don't scare ppl

Take the 400w chiller running for 8hrs a day...

400/1000(kW) x 8hrs = 3.2kWh/day

Cost per day = 3.2 x $0.2102(our tariff now) = $0.67264

So it cost only $0.67264 per day to run the 400w chiller for 8hrs a day... (idle time negligible)

Cost per month = $0.67264 x 30 = $20.1792

Hi,

I saw the power rating for Arctica chiller at www.eaquanature.com stated that DBS-150 is actually 600W. the 150W is the cooling capacity not the power rating. Am I rite?? Anyone can clarify??

[neokn]

Thanks for pointing out the typo error. And I forgot to multiply the cost of per kW.

Really, k.n.s.

So double checked calculation is as follows:

If your 150W chiller works 24/7. Then base on calculation

24 x 7 x 150 = 25.2Kw per wk

25.2Kw x 4 x 0.2102 = $21.19 per month

Compare a 400W chiller that works 8hrs a day

8 x 7 x 400 = 22.4Kw per wk

22.4Kw x 4 x 0.2102 = $18.84 per month

[jervismun]

lol I was so shocked by the $100+/month figure, almost fainted. Bought a Teco RA240 yesterday and it is 220W!!! So should be around $30+/month la. Ok la still can afford.
