Comparison of power consumption of different chillers

[tflow]

Hi,

Have a question to all our chiller experts here

Does any model/brand of chiller comes with heating functionality as well?

I asked because during weekdays, my office tank temperature is around 22-24 deg. Say if i get a chiller and set it to 25-26 deg (to cater for weekends), will the chiller be able to "heat" up my tank during weekdays (so as to minimize the temp fluctuation)?

Thanks.

Actually if you office temperature drops, you should get a heater instead.
Because once you set the temperature you wanted (like 25 degree), it will cut off once the temperature is reached.

Errr... by the way. I've managed to insulate the cannister and HOB filter housings (in/out hoses are already insulated) and power savings appear to be in the region of 15%
Will know for sure when i get my PUB bill at the end of the month

May I know how did you insulate your hoses and the cannister?

Hi Crfan, in this case, i would probably have to install heater for weekdays & chiller for weekends, if i want to maintain the temp at 24-25deg. Thought there might be some 2-in-1 solution in the market

Yes, Tflow-san.
Look for those that operate on the peltier effect (1 side hot other side cold). But think they are more suitable for small aquaria though.
Will look around and let u know later.

Hi Crfan-san,

With insulation foam used in AC system. Hoses are bought new from an AC servicing/supply shop in Sin Min. Make: Superflon (more flexible than the ordinary type insulation hoses)
Here's a pic taken with my hp. Sorry for poor quality though.

[tinydot]

those insulation foams r meant for copper pipes which are smaller in diameter compared to canister hoses, can squeeze in?

[Ebi]

Tflow-san,

Here are some of the model:

Pacific Coast CL-85: http://www.aquadirect.com/store/prod...cat=0&page=146

Pacific Coast CW-3000: http://www.dtpetsupplies.com/catalog...oducts_id=7427

Pacific Coast CH-PC-CW-1000: http://www.dtpetsupplies.com/catalog...e-programming/

Dunno what Brand VAS-CU02680 (Heater not included ): http://www.opentip.com/Home-Garden/H...p-1081798.html

Think you should browse around to see what you actually need though.

Thanks Ebi! Looks like the hose is worth getting!
May I ask which shop?

Tiny-san,

If you go to the "proper" shops/suppliers, they have a very wide variety of ID/OD sizes. I am using 5/8" ID x 1/4" Thick hoses. Sorry left receipt in office so can't remember full style address now. Not cheap though, think cost 2-3X the price of the not-so-flexible hoses.
It hard to explain until u try using the stiffer type. The ones i use no need to cut into smaller pieces, they are so flexible and powder coated inside, I jus slide the full length insulation hose over the filter hoses, add another pc if not long enough, and route the filter IN/OUT hoses as i need. Can't do this with cheaper but stiffer insulation hoses.

If you need full style address, will try to post tomorrow when i get hold of the receipts which i think I have left in my office.

However if you are familiar with the "famous" Salted-Duck Soup + Braised Duck" stall in 1 of the Sin Min HDB Coffee Shop, then you will be able to find the shop (those low car workshop building type) which is opposite that HDB. Think it's Blk 10 at the far corner shop. Name of company is "Precision xxxxx" (cant remember second part of the name).
They sell in 6ft lengths. Think it's S$5-S$6 per length.

Hi Ebi-san, really thanks for the links and advice Yup, will definately do more research before i decide what i really need.

While reading the first link for CL-85, find a disclaimer quite funny though:
"This is a thermal electronic chiller and will not work properly if the room temperature is warmer than the desired tank temperature."
Thought for singapore context (without air-con), that will be the norm?

You can also buy these insulation hoses at the clementi hardware store from the friendly auntie. Same block as green chapter.

Ranmasatome-san,

Friend bought from there before, say cheap about S$2-S$2.50 a pc, after installation, complain hoses become too stiff to route properly. I don't know what brand are the hoses though.

ahh i see, so based on the foam spec, you are using 16mm canister hose size?

[Ebi]

Yes Tiny-san, actually the hoses has this printed on it as well 16 x 6. I believe it refers to metric, i.e. ID-16mm x Thk-6mm.
Sorry guys the brand is Superlon not Superflon.

[Crfan]

Sharing some information with the community on the Superlon Insulation tubes which Ebi mentioned in his Chiller thread.

I have also attached a picture of the model to get if you are using 12/16
tubes and they have those that can fit 22 as well. The one below has no problems fitting 12/16 and the hose is still flexible after fitting on the insulation. But do note that the maximun length of each tube is about 6ft. (about 2m) and no longer. The shop is Precision Automech located at sector C Sin Ming Industrial estate at Block 10.
You can take bus 130 from Ang Mo Kio interchange.
Hope it will be useful to those who are looking at saving some costs when running their chillers.

Thanks alot for your infomation. Will get it when i go down this weekend

This Pacific Coast chiller is for the US market. Ours here in Singapore are known as Resun.

Hi Crfan-san,

Many thanks for the follow-up.
Thousand apologies to all, had been so busy with so many audits that I had totally forgotten to update with the full style address.
Any improvement in your power consumption so far?

By the way, wishing you and your loved ones + all AQ readers a merry and blessed merry christmas!!!
