Higher quality (and typically more expensive) electric fireplaces will generally look more realistic compared to cheaply made electric fireplaces.
One of the aims of an electric fireplace can be to resemble a particular real fireplace, such as a fireplace insert or a wood burning stove. In order for an electric fireplace to look like the real thing it needs to be of sufficient quality.
Thankfully, even the cheapest of electric fireplaces can look very real in terms of its quality.
We have a low cost electric fireplace stove, but it still has a metal body and good quality components that make it look like a real wood burning stove, wherever it’s placed in our home.
