Hi, how we all doing?
Saw this on ebay... thinking of getting one for a 47L.
yes or no or heres something better?
cheers.

My nano is ~50l and i dont run a chiller. USB powered fans run by a STC-1000 has been all ive needed to keep stable temps.

i was hoping to use this as then i won't have to put a heater in the display.

 

[lukusis]

In-line heater?

In-line heater?

yeah i thought about that do they have a pump inside them or need to supply one?
Also the ones I've seen are around 200W. over kill?

That uses a Peltier Cell and it can heat and cool.

For cooling, it is not as effective as evaporation or compressors.
The main advantage is - obviously - not having to deal with increased evaporation.
Main disadvantage is price and size/footprint, as you need more Peltier cells than fans to achieve the same result.

Irrespective of cooling technology, the tank will need to be topped up with fresh water. So, in such small tank, would I rather prefer a fan and the extra evaporation.

"Peltier junctions are generally only around 10-15% as efficient as the ideal refrigerator (Carnot cycle), compared with 40–60% achieved by conventional compression cycle systems (reverseRankine systems using compression/expansion).[16] Due to this lower efficiency, thermoelectric cooling is generally only used in environments where the solid state nature (no moving parts, low maintenance, compact size, and orientation insensitivity) outweighs pure efficiency."

So you saying the unit will be less effective and little maintaince? The room the tank is in doesn't get very cold or hot.

What is the average starting price for nano chillers?

What is the average starting price for nano chillers?

It may vary from $150 to $700
depends on quality and brand
