Comparison: Best 33 Inch Electric Fireplace Insert (Updated | Dec 19th)

A fireplace insert is a complete, self-contained unit designed to fit into an existing opening, offering a clean, built-in look. A log set consists only of the faux logs and ember bed and is meant to be placed inside a real fireplace. For a modern, flush finish, an insert is the superior choice.

First, measure the interior width, height, and depth of your fireplace or cabinet opening. You must ensure the insert’s listed dimensions are slightly smaller than your opening to allow for proper ventilation and a safe fit. Always check the manufacturer’s specifications for required clearance.

Heating capacity is measured in BTUs (British Thermal Units), with most 33-inch electric inserts ranging from 4,500 to 5,000 BTUs. This is typically sufficient to effectively heat a room of about 400 square feet. Consider the size of the room where the fireplace will be installed to ensure adequate warmth.

No, one of the main benefits of an electric fireplace is that the flame effects can be operated independently of the heat. This allows you to enjoy the cozy ambiance of the flickering flames all year round, even during warm summer months, without adding any unwanted heat to the room.

Fan-forced heaters use a fan to blow air over a heated element, which can dry out the air and create noticeable noise. Infrared heaters use invisible light waves to warm objects and people directly, resulting in a more natural, gentle warmth that doesn’t reduce humidity and is often quieter.

For the highest level of realism, look for models featuring LED technology with multi-color flame projections and ember bed lighting. Some premium models even include water vapor or smoke mist technology, which creates a lifelike, three-dimensional flame effect that is difficult to distinguish from a real fire.

The operating cost is surprisingly low, especially when using the flame-only effect, which typically costs just pennies per hour. When running the heater, the cost depends on your local electricity rate, but it’s generally more energy-efficient and cost-effective than running a central heating system to warm a single room.

Key features include a built-in thermostat for temperature control and an automatic safety shut-off that turns the heater off if it gets too hot. For installation, look for a unit with a simple plug-in design and mounting brackets to ensure it is secure and stable within your opening.
