Electric modern fireplace generates more heat compared to others. It can be used to places where there are no ventilations or where there is no space for chimneys. No installation is needed so you can save money. Moreover, you don't need to buy wood or gas to keep it functioning.
To assess practicality of the fireplace, we can judge it through its function. Its purpose is same as the classic wood fireplace and so is its function. It produces the same amount of heat as wood powered fire, eliminating the risk of flying sparks, smoke and other risks. These electric units generate no smoke and therefore don't require ventilation. There is no need of getting a chimney built or a duct system.
