A typical wine fridge is an appliance that uses 150 to 500 kilowatt-hours (kWh) of electricity per year. That equals about 0.4 to 1.4 kWh per day, or an average continuous draw of roughly 18 to 55 watts.
Small compressor wine fridges usually use less electricity than large built-in wine columns. Some thermoelectric models use more, especially in warm rooms. Published ENERGY STAR testing found vapor-compression wine chillers using 161 to 480 kWh per year and thermoelectric models using 183 to 803 kWh per year. The testing cited here was published in ****.
Wine Fridge Power Use at a Glance
| Wine fridge type or example | Annual electricity use | Approximate daily use | Average continuous draw |
|---|---|---|---|
| Efficient compact cooler | 156 kWh/year | 0.43 kWh/day | 18 watts |
| 54-bottle wine fridge example | 192 kWh/year | 0.53 kWh/day | 22 watts |
| 100-bottle built-in wine column | 285 kWh/year | 0.78 kWh/day | 33 watts |
| Large 80-bottle wine column | 475 kWh/year | 1.30 kWh/day | 54 watts |
These figures come from published specifications for the Zephyr PRW24C02CG, Hisense HWS054N6SS, Dacor DRW24980 and Bertazzoni REF24WCP wine storage models. Your fridge may use more or less electricity depending on the room temperature, temperature setting, ventilation and door openings.
How Many Watts Does a Wine Fridge Use?
Most wine fridges have a rated power draw of about 80 to 150 watts while the compressor or cooling system is running.
Examples include:
- The Hisense HWS054N6SS is rated at 80 watts and uses 192 kWh per year.
- Several Whynter wine refrigerators list maximum power consumption between 80 and 100 watts.
- The Bertazzoni 80-bottle wine column lists a 152-watt power rating and annual energy use of 475 kWh.
The wattage rating does not show how much electricity the fridge uses over a full year. A 100-watt fridge running continuously would use 876 kWh per year. Compressor models switch on and off, so their actual annual consumption is lower.
How Much Does a Wine Fridge Cost to Run?
A wine fridge's annual running cost is:
Annual running cost = annual kWh consumption × your electricity price per kWh
At an electricity rate of $0.18 per kWh, the annual cost would be:
| Annual energy use | Approximate annual cost |
|---|---|
| 156 kWh | $28 |
| 192 kWh | $35 |
| 285 kWh | $51 |
| 475 kWh | $86 |
Your cost will depend on your utility rate. Use the annual kWh figure from the product specification sheet rather than the wattage rating when estimating operating costs.
What Affects Wine Fridge Electricity Use?
A wine fridge uses more electricity when it has to remove more heat or run more often. The main factors are room temperature, cooling method, temperature setting, ventilation and door openings.
Room Temperature
A wine fridge uses more electricity in a hot room because the cooling system has to remove more heat. ENERGY STAR identifies surrounding temperature, door openings and how full the appliance is as factors that affect actual energy use.
Thermoelectric Versus Compressor Cooling
Compressor wine fridges are generally better suited to larger capacities and warmer rooms. Thermoelectric models are often quiet and compact, but testing found that some used much more electricity and had difficulty maintaining their target temperature in warmer conditions.
Temperature Setting
A fridge set to its coldest temperature usually runs more often than one set to a moderate wine-storage temperature. Set the cabinet no colder than your wine requires.
Installation and Ventilation
Built-in wine fridges need the clearance specified by the manufacturer. Restricted airflow can make the cooling system work harder and increase electricity use.
Door Openings and Lighting
Opening the door releases cold air, so frequent openings can increase cooling demand. Interior lighting also uses electricity, although the cooling system usually accounts for most of the appliance's energy use.
How to Choose an Energy-Efficient Wine Fridge
Compare wine fridges in this order:
- Annual energy consumption in kWh per year
- Bottle capacity
- Cooling method: compressor or thermoelectric
- Single-zone or dual-zone design
- Built-in ventilation requirements
- Maximum power rating in watts
For most households, a wine fridge using under 200 kWh per year is relatively economical. A larger built-in model using 300 to 500 kWh per year may still make sense when you need more bottle capacity, but it will cost more to operate.
Before buying, compare the annual kWh rating with your electricity price and the storage capacity you need. The yearly figure gives you a better estimate of running cost than the wattage printed on the appliance.
