Electric fireplaces may be popular, but they use a lot of energy. They can cost twice as much to operate than other types of heaters and could cause your power bills to skyrocket if you don’t turn them off when not in use or switch to less expensive fuel sources like solar panels instead. If you do go for an electric fireplace though, the U.S. Department of Energy recommends using one that is no larger than 20 inches wide because bigger ones tend to consume more watts per hour (and dollars). Also make sure it is made by a reputable company with high product ratings from customers on sites such as Amazon so there are fewer problems down the road! Electric fireplaces may be aesthetically pleasing, but unless you plan to turn them off when you leave the house, they can be a major drain on your energy bill.
