280W or 650W chiller for my set-up? :)

[blondmyth]

Hi reefing shifus,

I've got a 2 by 1.5 by 1.5 set-up (30 gallons).

Currently running 2 X 24W T5 (white), planning to get another 2 blue T5 tubes, and assuming they are of the same wattage, they would mean a total of 96W in total.

For a 30 gallon setup running on 96W of T5, would a 280W chiller or a 650W chiller use lesser electricity? (after factoring in the number of kick ins for 30 gallons of water)

Specifically, im deciding between the resun CL-280 and CL-650.

Thanks all!

I would get the resun CL-280.

U need to take into consideration the heat generated by the pump and also at what temperature u 1 2 keep at

[blondmyth]

Using a hang on filter, so pump isn't submerged. What is submerged though is a 101 sunsun wavemaker and bubble magus nac qq skimmer which uses a atman 200lph I believe. Both of which doesn't produce that much heat?

Any thermal engineers here?

thanks iczboy for your input.

any others?

cheers

If I were you I go for CL650 due to:

1. high rating means i will be able to use it if i intend to add more lights or upgrade my tank
   
2. it takes the 650 shorter time to cool down the tank thus its does not means that the 650 will consume more electricity

Thanks for your input Gouldian.

Say i do not upgrade my tank or add any more lights, would 650 be too much of an overkill for my 30g?

[Gouldian]

If you have already made up you mind to stick with a 30g, then just go for the 280.

[blondmyth]

any idea for the recommended flowrate for the CL-280?

cheers

[iczboi]

you can consider getting HS-28A. Which can chill up to 150L of water. Flow rate between 200 - 1200L

Specs for the Resun CL-280 is at this URL: http://www.resun.com.cn/En/ProductInfo.aspx?ProID=784&ProClass=141

The recommended pump outflow is 500 to 1000 L/Hr.

To be very accurate on the power consumption the numbers of kick in and how long the kick in takes does plays a important role.

But if you are not going to upgrade your tank in the future, there is no point investing in a bigger Wattage chiller. The different will not be too much for a 30g tank.

thanks. bought the 280 about a month or two back.
