I am looking to buy an electric dryer for a small 24" space, and there seem to be two options. The 120W up to 1500W, and the 240V unlisted unknown power rating units.
My main goal is to get a short drying time. But if both type of units are the same wattage, then the 240V units would not have any advantage. Even if they are like 1900W versus the maximum 1500W then it is not a huge improvement. Most of the market of 24" dryers are only available in 120V, while the 240V units are rare or expensive.
For a resistive load like most of the power consumed by a clothes dryer, power factor is pretty much 1, so V x A = W. A 1500W 115V dryer would draw around 13A, which is tippy top for the usual 15A household circuit and really should have a 20A circuit - which is not so common in residential.
On the other hand, the same 15A circuit at 230V will permit something more like 3000W which is tons more heating.
The high voltage dryer is always going to outperform the low voltage one.
Do you have a suitable 230V circuit in the location of concern? It's expensive to run a 230V circuit which will usually have to come clear from the panel.
typically, a 240v dryer is in the 5000-6000W range.
they are breakered 30amps on #10 wire to cover the element and the motor.
a 120v dryer will take all month to do half the job...
Yep, had a 120 volt dryer/washer combo that we had in an RV at one time. It took forever to dry clothes!
240 volts is the way to go, assuming you have the service in the home.
Or, better yet, if you have natural gas or propane available they work very well too.
