You should place your wine cooler in a room where the ambient temperature is above 15 degrees and does not fluctuate too dramatically, this will ensure that it can function correctly.Most wine coolers are now fitted with winter safety systems which allows them to be placed in garages or cellars if the temperature does not drop below 0 degrees.
Compressor cooling works more like a refrigerator, and it is the most efficient cooling system. They make a noise when the compressor comes on – keep this in mind and select a cooler with a low noise level.Thermoelectric cooling works a little like the cooling technology used in cool boxes. They use a Peltier device, which cools a large surface area. The cool air is then circulated by fans. Thermoelectric wine coolers are generally quieter than compressor coolers however they are not as effective.
This really depends on what you plan to store in your wine cooler:A single zone cooler will be a great option for you if you are storing one type of wine.You will need a dual zone cooler for storing both red and white wines.Three zones are useful if you would like to store red and white wines as well as champagne.
A normal noise level for wine coolers is around 40dB. You will hear the compressor working occasionally to keep the unit cool and the unit will never be completely silent so you should consider this, in particularly, if you are placing your wine cooler in a room where you spend lots of time.
