Consider the power source
While with washers you may not have a choice, dryers are made in both electric and gas models. It is important to note whether your dryer will need to be powered by electricity or gas.
Example of a 220V outlet used for an Electric Dryer
Example of a gas line connection used for a Gas Dryer.
In addition to this connection, a standard electrical outlet should be near by.
If you live in an apartment or a condominium you may need to confirm with your leasing professional or landlord which option you need.
