Gas Dryers vs. Electric Dryers: What’s the Difference?

If you’re not poking around behind your appliance, you might not know exactly what’s going on inside. What type of dryer do you have? Is it gas or electric? If you’re going to purchase a new dryer, you need to know what to look for. We explain everything you need to know about gas vs. electric dryers in this guide.
Can I choose gas or electric?
You can choose whether you want to have a gas or electric dryer, but you should make that decision based on your existing laundry hookups. It can be expensive to change your laundry hookups from gas to electric and vice versa, so it’s best to stick with what you have.
Sometimes, laundry rooms have both a gas hookup and a 240-volt electrical outlet. If your laundry room can support electric or gas, which is occasionally the case for homes with gas service, you can choose which type of dryer you want. On the other hand, if you’re not set up for gas and don’t want to go through a whole installation process, electric is your only option.
How can I tell if I have a gas or electric dryer?

Jenny McGrath / Digital TrendsIf you just moved into a new place with a washer and dryer hookup but no appliances, you can tell by simply looking at the outlet. Gas dryers run on electricity to do things like power the lights and turn the drum, but they heat with gas. So, the outlet should look pretty typical, and there will be a capped off gas line in the vicinity. If the outlet is larger — it may have three or four holes for prongs — and you don’t see a gas line, chances are you’ve got an electric setup (which typically runs on 240 volts). You can snap a picture of the outlet and bring it with you to the appliance store, and they should be able to confirm for you.
For those of you who have an existing dryer, you can always check out the model number. Gas dryers usually have a “G” somewhere in the jumble of letters, while electric ones have an “E.” This isn’t necessarily foolproof, though. Whirlpool makes a dryer with the model number WGD4815EW, which has both an “E” and a “G.” However, the electric version has two “E’s” in its number: WED4815EW.
How do gas and electric dryers work?
Both types — gas and electric — use heat, air, and tumbling to get your clothes dry. The airflow and tumbling go hand in hand. While electric dryers use a heating element, gas dryers have a gas burner. In the former, electric current travels through the heating coil, building up electrons and heating up the metal and in turn, the air. The heated air is then sent into the drum via a blower or fan.
Using natural gas or propane, gas dryers use an igniter to burn the gas. As with the electric version, a blower or fan draws the hot air into the drum.

Both electric and gas dryers get vented to the outside, thanks to the moist, lint-filled air they expel. Otherwise, you could find yourself with a mildew-filled laundry room, not to mention lots of fluff particles in the air you’re breathing. In addition, the vent on a gas dryer exhausts out the products of combustion, which you also don’t want to inhale. Ventless electric models are often found in apartments because they don’t need to exhaust the air outside. Many of these models are compact, but there are full-size ventless dryers available, like the Whirlpool Duet.
There are two main types of ventless dryers: Condenser and heat pump, and they each work a little differently. With a condenser dryer, the air is heated by a condenser and then travels to the drum and starts evaporating the water from the wet clothes. Air returns to the condenser for a cool down, and while the moisture condenses, the air gets reheated and returns to the drum to start the cycle over again. One thing to keep in mind is that if you don’t have a drain to divert the condensed water, it will collect in a tray you’ll need to empty after each use. Heat pumps use a refrigerator-like compressor technology, recirculate the air, and remove moisture from the clothes and air. They use lower temperatures than conventional dryers and are therefore gentler on clothes.
These dryers are more efficient energy-wise — the heat pump is the most efficient — but their cycles take longer than their vented counterparts.

How much does each type cost?
Up front, you’re going to pay around $50 to $100 more for a gas dryer, not to mention the installation cost. Gas dryers are more energy-efficient in the long run, according to Energy Star, though that may depend on rates in your area. However, washers also spin much faster than they did in the early ’80s, meaning clothes aren’t as wet going into the dryer.
There are now Energy Star-certified dryers, in both electric and gas versions, and the agency says these dryers use 20% less energy than standard models. They use moisture sensors to stop the dryer when clothes are dry instead of running the entire cycle and lower heat settings that increase dry times but use less power. This can reduce energy costs. According to Energy Star, you’ll save about $215 with the Energy-Star certification. Keep in mind that savings are over the entire life of the appliance. Therefore, depending on how much you spend on your dryer, your savings may not be enough to recuperate the extra money you spent, but you’re also reducing your footprint too.

Manufacturers tend to keep the features the same for the electric and gas versions of the same dryer. Take the Whirlpool model from above: Both have 14 cycles, auto-sensing technology, and four heat levels.
So, which way should you go: Gas or electric? If you only have an electric hookup, go with an electric dryer because adding a gas line is an added expense. Plus, with so many different models to choose from, you can find a good, energy-efficient electric dryer that will fit your needs. If you have a gas hookup, choose a gas dryer. If you happen to have both hookups, electric and gas, consider the pros and cons of both types and make the best decision to accommodate your laundry habits and individual financial situation.
