Chiller for outdoor pond

[jcon]

Hey Guys

I am looking for a chiller for a 220litre outdoor pond, i need it to be able to keep the temperature at around 12-18 degrees through summer. Which chiller will be able to handle this?

The ones i've seen all look to be used to keep the temperature at 25-26 degrees, can chillers handle the lower temperatures?

The pond will also be undercover on the balcony, out of the sun.


Cheers
Josh

Will a 1 HP Chiller be sufficient?

Chillers are expensive to purchase as well as to run...

Keeping an open top outdoor container 10*C cooler than the air temperature above it will cost a fortune...

I have not thoroughly researched this exact situation in detail.... but I have researched heating outdoor containers in cooler air temps... Even with extensive insulation on the sides and bottom of the container, having extreme differences in air/water temps at the surface makes heating/cooling very difficult or at least very expensive.

Yes I have heard they are expensive. The pond is on a covered balcony, out of the sun, the pond itself is also covered. Being that it is only 55g, and that the chiller is only going to be used through summer, I thought I could keep the costs down.

I was also think about cutting up an old foam esky and silconing it to the sides and bottom to increase insulation. I really need to keep the water temp below 20 degrees celcius.

Thanks for the feedback, anyone else?

When you said pond, I think many people including myself were thinking like 2000 gallons. If it's only 55 gal then it should be a lot more affordable. Check out reefcentral. Chillers are commonplace in reef setups due to all the heat from equipment and lighting.

If the original post was read instead of the title, one would find all the information given.

What I want to know is if there is a chiller that can keep a 220l pond at 12-18 degrees celcius, and if so, which one.

Thanks for your input.

Nobody knows what a liter is. If you look around on the 'net and especially on reef keeper sites where they use chillers a lot, you'll find ways to calculate how big of a chiller you'll need.

have you thought about using a fan to blow air over the surface of the water too cool via evaporation?

A Litre is a measurement of water, there is 4L to a gallon. a 55g metric of water would equal 220l.

Here in Australia we commonly use celcius instead of farenheit, and litres instead of gallons, unless you did your schooling in the older days.

Thanks, I will look into it. My only concern was that a chiller is most commonly used to keep the salt water tanks at 26 degrees, I am just not sure if they are designed to keep water at 12-18 degrees, thus needing a more powerful chiller for my size tank, or it not even working at all.

I will give that a go too, not sure how much it will help though.
