8 calculators
Air Conditioner
1000-4000W | 8.0h/day typical
Window and split-system air conditioners range from 1,000 W for small rooms to 4,000 W for large units. A mid-size 12,000 BTU unit draws roughly 2,000 W.
Ceiling Fan
20-70W | 8.0h/day typical
Ceiling fans are extremely energy-efficient, drawing just 20-70 W. They cool by creating a wind-chill effect on your skin, not by lowering room temperature.
Dehumidifier
240-500W | 10.0h/day typical
Dehumidifiers draw 240-500 W and often run for extended periods. Compressor-based models are more efficient in warm conditions, while desiccant models work better in cold rooms.
Space Heater
750-3000W | 8.0h/day typical
Portable electric space heaters typically draw 750 to 3,000 watts. Most common models for a single room run at 1,500 W on their highest setting.
Air Purifier
20-70W | 12.0h/day typical
Air purifiers with HEPA filters draw 20-70 W on their standard settings. Models with auto mode adjust fan speed based on air quality, reducing average consumption.
Humidifier
30-350W | 8.0h/day typical
Ultrasonic humidifiers draw just 30-50 W, while steam humidifiers can draw up to 350 W. Evaporative models sit in the middle at 30-100 W.
Water Heater
3000-8800W | 3.0h/day typical
Electric tank water heaters draw 3,000-8,800 W to heat and maintain water temperature. A 150-litre tank typically uses a 4,500 W element.
Electric Boiler
6000-14000W | 2.0h/day typical
Electric central heating boilers draw 6,000-14,000 W when actively heating. They cycle on and off based on thermostat demand, so average daily consumption depends on insulation.
Kitchen
19 calculators
Dishwasher
1200-2400W | 1.0h/day typical
Dishwashers typically draw 1,200-2,400 W per cycle, with most energy used to heat the water. Eco modes reduce both water and electricity consumption.
Electric Kettle
1200-3000W | 0.2h/day typical
Electric kettles draw 1,200-3,000 W, with European models typically at 2,000-3,000 W. They are extremely efficient at boiling water, converting over 95% of energy to heat.
Electric Oven
2000-2400W | 1.0h/day typical
Electric ovens draw 2,000-2,400 W when actively heating. Fan-assisted ovens distribute heat more evenly, allowing you to cook at lower temperatures.
Freezer
30-100W | 24.0h/day typical
Standalone chest and upright freezers cycle between 30-100 W average draw. Chest freezers are more efficient because cold air sinks and stays inside when opened.
Microwave
600-1700W | 0.3h/day typical
Microwaves typically draw 600-1,700 W of input power. A standard 800 W cooking power microwave actually draws about 1,000 W from the wall due to magnetron efficiency.
Refrigerator
100-400W | 24.0h/day typical
Modern refrigerators cycle their compressor on and off, averaging 100-400 W depending on size and efficiency rating. EU A-rated models average around 150 W.
Air Fryer
1400-1800W | 0.5h/day typical
Air fryers draw 1,400-1,800 W but cook food faster than a conventional oven. A typical 4-litre model runs at about 1,500 W.
Bread Maker
450-800W | 0.5h/day typical
Bread makers draw 450-800 W during the kneading and baking cycle. A typical loaf takes 3-4 hours but the heating element cycles on and off, averaging about 600 W.
Coffee Maker
800-1500W | 0.3h/day typical
Drip coffee makers draw 800-1,500 W during brewing, with the hot plate using 70-80 W to keep coffee warm. Pod machines typically draw 1,000-1,400 W briefly.
Induction Hob

Induction hobs draw 1,400-1,800 W per cooking zone but transfer heat more efficiently than gas or ceramic. They heat only the pan, wasting very little energy.
Slow Cooker
160-300W | 6.0h/day typical
Slow cookers are remarkably energy-efficient, drawing just 160-300 W over several hours. Even after 8 hours of cooking, they use less energy than an oven running for 1 hour.
Toaster
800-1800W | 0.1h/day typical
Toasters draw 800-1,800 W for a short 2-3 minute cycle. A 2-slice toaster typically runs at about 1,200 W. Despite the high wattage, daily cost is very low due to brief use.
Electric Frying Pan
1000-1500W | 0.5h/day typical
Electric frying pans draw 1,000-1,500 W. They maintain temperature more evenly than stovetop pans and can be more efficient for slow cooking tasks.
Electric Pressure Cooker
700-1000W | 0.5h/day typical
Electric pressure cookers like the Instant Pot draw 700-1,000 W during pressurization, then drop to 200-300 W to maintain pressure. They cook food 70% faster than conventional methods.
Electric Stove
1200-2000W | 1.0h/day typical
A single electric stove burner draws 1,200-2,000 W. Ceramic and coil burners waste more heat than induction, which is 84% efficient versus about 70% for ceramic.
Espresso Machine
1000-1500W | 0.2h/day typical
Home espresso machines draw 1,000-1,500 W during heating and extraction. Thermoblock models heat on demand, while boiler models maintain temperature continuously.
Food Dehydrator
300-1000W | 8.0h/day typical
Food dehydrators draw 300-1,000 W and typically run for 6-12 hours per batch. A standard home model uses around 800 W with a fan and heating element.
Rice Cooker
200-800W | 0.5h/day typical
Rice cookers draw 200-800 W during the cooking phase, then switch to a 20-30 W keep-warm mode. A 1-litre cooker typically runs at about 500 W.
Sandwich Maker
600-1000W | 0.1h/day typical
Sandwich makers and panini presses draw 600-1,000 W for a short 3-5 minute cycle. Despite the wattage, daily cost is negligible due to very brief usage.
