More Power-Hungry Than Refrigerators and Washing Machines! Taipower Reveals Top 10 'Power-Guzzling Monsters' in Homes, With Standby Mode Silently Burning Money—'Never Thought to Turn Off'

Temperatures across Taiwan continue to rise, and with summer electricity rates now officially in effect, the operation frequency of various household appliances has significantly increased, causing many people's electricity bills to soar. How to maintain quality of life while precisely saving energy and avoiding unnecessary power waste has become a top concern for every household. Among the various appliances frequently used in daily life, which devices are the invisible 'power-guzzling monsters'? The 'DailyView Network Temperature' analyzed the most discussed 'Top 10 Power-Consuming Appliances' over the past year and included practical energy-saving tips recommended by Taipower to help you master correct electricity usage habits and easily protect your wallet!

Rank 10: Rice Cookers and Rapid Cookers

Rice cookers and rapid cookers, common in kitchens, have heating power ranging from 600W to 1,400W during operation, making their power consumption quite significant. These kitchen appliances have two common power consumption pitfalls: first, 'using a large pot to steam small amounts of food,' which reduces heating efficiency; second, 'remaining in warming mode for long periods.'

After the rice cooker switches to warming mode, the power consumption is about 40W. If you habitually leave it plugged in all day, the electricity used just for warming can approach 1 kWh. Additionally, although microcomputer rice cookers offer precise temperature control, their longer cooking times mean that habitual long-term warming can accumulate considerable power consumption.

Energy-saving tips:

Turn off immediately: After food is cooked or steamed, immediately turn off the power and unplug the device. Do not use the rice cooker as a long-term warming container.

Use modes and accessories wisely: Use the 'quick-cook mode' on electronic rice cookers to shorten operation time. When heating with a rapid cooker, always cover the pot to trap heat and improve heating efficiency.

Rank 9: TVs and LCD Monitors

Modern TVs and LCD monitors may lack high-power heating components, but their power consumption concerns mainly stem from 'screen size and panel technology' and the often-overlooked 'peripheral standby power.' As TV screens grow larger and picture quality and chip computing technologies improve, the electricity needed for panel illumination soars. Moreover, many smart TVs and connected cable set-top boxes remain in networked standby mode even after being turned off. If left plugged in 24/7, they silently consume significant amounts of ineffective power over a year.

Energy-saving tips:

Centralized power-off: Connect TVs, set-top boxes, and audio equipment to a power strip with an independent switch. When not in use, turn off the main power to avoid standby power consumption.

Use power switches: Develop the habit of fully turning off the power when temporarily leaving or not watching, rather than just displaying a black screen or activating a screensaver.

Rank 8: Electric Water Heaters

Among various appliances, electric water heaters are notorious power-guzzling monsters. Many people only notice the instantaneous heating power of up to 10,000W in instantaneous-type units, but overlook the 'continuous insulation energy consumption' of storage-type water heaters. Storage-type water heaters automatically and repeatedly 'dissipate heat and reheat' throughout the day to maintain water temperature, causing massive invisible power waste.

Energy-saving tips:

Install a timer: Pair storage-type water heaters with a timer, setting it to automatically power on and heat one hour before bathing, then automatically cut power after use or at night to avoid prolonged repetitive insulation power consumption.

Lower temperature in summer: In warmer summer months, reduce the heating setting on instantaneous water heaters and use water-saving showerheads to control flow, further reducing operational load.

Rank 7: Electric Fans

Electric fans are generally seen as energy-saving appliances, but their power consumption differences mainly lie in motor technology and usage patterns. Traditional AC fans consume about 50W to 80W, while newer DC inverter fans require only 20W to 30W—more than double the difference in operating power. Additionally, water-cooling fans with pump operation consume more power. Using them in humid summer environments inside air-conditioned rooms can increase indoor humidity, indirectly increasing the air conditioner's dehumidification and operational burden.

Energy-saving tips:

Use wisely with proper models: Prioritize DC inverter fans. When using circulation fans, place them diagonally opposite the air conditioner to accelerate cold air circulation and reduce compressor load.

Regular cleaning and correct usage: Clean fan blades and grilles regularly to prevent dust buildup from increasing motor resistance. Use water-cooling fans in well-ventilated areas to avoid increasing indoor humidity.

Rank 6: Electric Hot Water Pots and Water Dispensers

The energy consumption of electric hot water pots and water dispensers is often overlooked, primarily due to their 24/7 insulation and repeated heating mechanisms. Although their insulation power isn't high, the cumulative power consumption over time is substantial. For larger-capacity water dispensers, annual standby insulation power usage can reach several hundred kWh—exceeding even a high-efficiency double-door refrigerator.

Energy-saving tips:

Change heating and water storage habits: Replace electric hot water pots with a rapid-boil kettle and a non-electric vacuum insulated bottle. Heat water only when needed and store it in the insulated bottle to avoid 24-hour continuous insulation power consumption.

Use timers and temperature settings: Utilize the timer function on electric hot water pots to automatically turn off during sleep or when away. Lower the insulation temperature to an adequate level (e.g., 90°C) to effectively reduce heating power consumption.

Rank 5: Electric Heaters

Electric heaters are high-power heating appliances with power consumption between 800W and 1,500W. These devices consume large amounts of electricity when converting electrical energy into heat. If used for long periods to heat entire rooms during cold seasons, the accumulated electricity cost is significant, making them one of the highest power-consuming household devices.

Energy-saving tips:

Use inverter air conditioners: For whole-room heating, prioritize inverter air conditioners. Direct airflow downward and use fans to assist convection, improving heat transfer efficiency.

Use electric blankets for localized warmth: When only personal localized warmth is needed, use electric blankets (around 60W to 150W) instead of high-power electric heaters to greatly reduce power consumption.

Rank 4: Washer-Dryer Combo Machines

Washing and spinning cycles mainly rely on motor rotation, with relatively low power consumption per cycle. However, using drum washer 'warm water wash' functions or activating traditional 'electric heating' drying modes causes internal heating elements to run at full power, instantly increasing power from 1,000W to 1,500W. Since wash-dry cycles typically take a long time, prolonged heating becomes a major source of household energy consumption.

Energy-saving tips:

Use cold water and batch processing: Prioritize 'normal temperature' or 'cold water' washing modes for regular laundry, and accumulate clothes to about 80% capacity before washing to avoid frequent small loads.

Optimize drying efficiency: Regularly clean lint filters before drying to maintain smooth airflow. Increase spin speed and add dry towels to absorb moisture, shortening subsequent drying time.

Rank 3: Dehumidifiers

Dehumidifier energy consumption mainly depends on 'operating principle' and 'room airtightness.' Common compressor-type dehumidifiers are more energy-efficient, while heater-based desiccant wheel types consume relatively more power. Additionally, if doors and windows are left open during dehumidification, allowing continuous inflow of outdoor moisture, the machine will run at full power continuously, wasting electricity unnecessarily.

Energy-saving tips:

Maintain airtightness and promote airflow: Always close doors and windows during dehumidification. Place the unit in the center of the room and use a circulation fan to accelerate air circulation, shortening high-power operation time.

Choose high-efficiency models and clean regularly: Select models with Energy Efficiency Level 1 certification. Set indoor humidity to 50%–55%, and clean filters every two weeks to maintain smooth airflow.

Rank 2: Refrigerators and Freezers

Refrigerators must run 24/7 year-round. Although single-cycle power isn't high, the total accumulated electricity consumption over time is astonishing. Overfilling the fridge blocks cold air circulation, storing hot food, or insufficient surrounding heat dissipation space forces the compressor to run frequently to cool down, significantly increasing power consumption.

Energy-saving tips:

Control storage volume and maintain airflow: Store food up to 80% capacity in the refrigerator, leaving gaps for even cold air circulation, and avoid placing hot food directly inside.

Pay attention to heat dissipation and sealing: Leave at least 10 cm of heat dissipation space between the fridge and the wall. Regularly check if door seals are aged or loose to prevent cold air leakage.

Rank 1: Air Conditioners

Air conditioners are the highest electricity-consuming household devices during summer. Traditional fixed-frequency AC units stop the motor after reaching the set temperature and restart with high current when room temperature rises, making frequent startups extremely power-intensive. Inverter AC units switch to low-frequency continuous operation after reaching the set temperature, greatly reducing power consumption. When purchasing, refer to the 'CSPF (Cooling Seasonal Performance Factor)' index and Energy Efficiency Level 1 certification, and select the appropriate AC capacity based on room size to avoid overload operation.
