Operating cost of chiller

[megatron]

Hi...

been trying to do some electric bill calculation for operating a chiller.

Pls correct me if I made any mistakes.

Based on the Singapore Powers website, a 200watts electrical appliance

costs 4.10cents per hour.

So operating a 200 watts chiller each month would cost =

4.10cents X 24 hours X 30 days = 2952 cents = $29.52

Is this correct?

Or is the running cost lower than this?

Pls advise.

Many thanks in advance.

it is correct if the chiller kicks in 24hrs....but in the case of having a oversize chiller, the chiller will kick in barely for half a day(total duration)...

so its definitely cheaper then $29..

where you see the info? not 18.88 cts/kWh for now but 20.52 cts/kWh from 1 July 07.

Hi Larry,

based on the 20.52cents per kWh rating... I arrive at very similar figures as per using

4.13cents for 200 watts per hour.

The website you recommended calculate it at $29.96.

But like wat bro Alvin mentioned... this $$$ is for a chiller working 24hrs non-stop.

With an oversized chiller or a smaller workload, the figures shld be lower than $29.

Any one monitoring their electric bill can share their findings?

Thanks ...

Sry for asking this.

Chiller can don't run 24 hrs non-stop?

Because of the water to be around 24-26 which I nvr set up my tank at my house but in office instead

Free Chiller

Hi Larry...

I have the same thots abt the free chiller..

I got a freshwater fish tank in my office.. and the air-con is set at 20degrees.

So the water in the tank is very cold.

So far the tetras and goldfish are happy with the temp..

If only I could set up my marine tank in office... then FREE chiller..

Not sure abt the chiller not working or working 24hrs...

I'm still comtemplating abt getting a chiller for my home marine tank

hence I started this topic to get advise and suggestions from Snr reefers..

Other alternative is to diy a chiller... either using those mini fridge or diy from a thermoelectric

chiller.. still collecting ideas and ideas from various forums.

[ah fat]

if im not wrong, the diy thermoelectric is already 80w. plus the small HOT filter which you will need also around 5 to 10w. than it doesn't cools the water if the tank bigger than 2 ft. and since it got no thermostat so it runs 24hours. end up, chiller better. ha

though im only using fan..

Free Chiller

every chiller will hav a built in thermomstat...once the chiller manage to chill the water to the desired temperature set by you. it will cut off the compressor...

it has the same logic as a iron...

Haha,

Because of the free chiller in office which the water alway stay around 21-24, I choosed to have my marine tank there.

Wanted to have a marine tank at home but the chiller will incurred additional cost to the bill.

Anyone having a marine tank with coral, LR and LS without a chiller can share on how to maintain a cool temp for the water.

Has anyone ever wonder why the fridge in our kitchen is only operating

at abt 140 watts and its able to keep so much food cold PLUS make ice.

But the tiny chiller that we use to chill the water to 24 - 26 degrees celcius

operates at 280, 450 or 650 watts?!

Thats like more than double the wattage of the fridge?

Is it a case of bad industrial design of chiller makers?

Hmmm.....
