When shopping for an electric fireplace, it is easy to focus on the practical details first. What size will fit the wall? How much heating power do I need? What is the price? How difficult will installation be? These are all important questions, but there is another detail that can have a major impact on your experience: electric fireplace flame technology. The flame effect is one of the most visible parts of the fireplace, influencing how it looks, how it feels within your room and how realistic the fire appears.
