Heat pump dryers are the most energy-efficient type of dryer. They use a closed-loop system to recycle warm air and extract moisture, consuming up to 50–70% less electricity than conventional vented models.
Fact: an efficient heat pump dryer uses 60% less energy than a conventional dryer. Always remember clothes dryers are more efficient when fully loaded.
The most energy-efficient tumble dryers - hence the cheapest to run - are heat pump tumble dryers. Condenser dryers come next, closely followed by vented dryers. Gas tumble dryers are comparable to heat pump dryers in terms of energy efficiency and cost.
Top Seven Appliances that Use the Most Energy in Your Home
Electric dryers span a wide range of wattages, from about 2,000 to 6,000 watts. That translates to about 2 to 6 kWh of electricity. Based on the national average rate of 12¢ per kWh, each hour of electric drying will cost somewhere between 24¢ and 72¢, depending on the model.
Here are the most significant home electricity users:
Typically, a dryer can finish a load of clothing in about 30 to 45 minutes, but there are a lot of variables that come into play.
The Top Energy-Draining Appliance: Space Heating & Cooling
This includes both forced-air systems, heat pumps, furnaces, baseboards, window A/C units, and fans. Because they run for long periods and often at high wattage, they dominate the consumption profile.
The Top Five Appliances in Need of Repair Before They Break
Microwaves are surprisingly energy-efficient, especially compared to ovens and stoves. Heating leftovers in the microwave typically uses less energy than warming them in an oven. That said, induction cooktops are another efficient option, heating food faster and using less electricity than conventional electric stoves.
Electric heating systems and tumble dryers tend to be the most expensive electrical items to run because they use large amounts of power over extended periods. Other high-cost appliances include electric ovens and immersion heaters.
Heat Pump Tumble Dryers
Heat Pump dryers are said to be the most energy-efficient dryers, as they do not require a lot of electricity. Like condenser dryers, these dryers also have an energy rating between A+++ to B. Both a heat pump tumble dryer and a condenser dryer are designed to dry clothing efficiently.
The cheapest time to use your dryer will depend on your energy provider's non-peak hours, which are usually early in the morning or late at night. If you like starting your day feeling accomplished, you can start a load of laundry while your coffee brews.
Top 10 Most Energy Efficient Dryers (2025)
To enhance the efficiency of household tumble dryers, we propose introducing an SI that would effectively phase out the sale of more inefficient gas-fired, air-vented, and condenser household tumble dryers.
Instead, most Amish families rely on clotheslines in the summer — and they still work in the winter, Williams said. According to appliance company Speed Queen, "Drying on a line in winter is actually a form of freeze-drying thanks to sublimation — or ice evaporating from a solid state.
Many folks go by the 50-50 rule. If the appliance has reached 50 percent of its expected life and it costs more than 50 percent of the cost of new, buy a new one. Oven failures can start with underperformance. For example, a family favorite just doesn't come out like it used to.
It should go without saying that kitchen countertop appliances should always be unplugged when they're not in use, whether you're leaving the house or not. This includes everything from toaster ovens, air fryers, Instant Pots, and slow cookers.
Top energy-consuming appliances and devices
Heating and cooling systems: Your HVAC system is typically the largest consumer of energy in your home, accounting for about 32% of your home's usage.
Appliances to Be Careful About Using For Too Long
Refrigerators and high-quality cooking appliances tend to have longer lifespans, often reaching 15-20 years with proper care.
Electrolux. Electrolux's over-the-range microwaves received the worst reliability score among all of the brands included in the survey, and its dishwashers are also among the least reliable.
Idle Appliances
Common culprits include TVs, cable boxes, printers, phone chargers and kitchen appliances. Even when powered down, these idle appliances consume electricity that shows up on your energy bill.
Many people leave their kettle plugged in at all times, thinking it doesn't use much power. However, kettles with digital displays or standby functions can still draw electricity even when they're not actively boiling water. How to Reduce Standby Energy Waste: Unplug the kettle when not in use.
The two appliances with the highest power requirements are typically:
