Buying Guide for an 18 Inch Electric Fireplace Insert

Understanding What an 18 Inch Electric Fireplace Insert Is

When I first looked into electric fireplaces, I learned that an 18 inch electric fireplace insert is designed to fit into existing fireplace openings or cabinetry. Its compact size makes it ideal for smaller rooms or spaces where a full-sized unit would be overwhelming. These inserts provide both aesthetic appeal and supplemental heat without the hassle of real flames or venting.

Measuring Your Space Accurately

Before making any decisions, I measured the width, height, and depth of my fireplace opening. Since the insert needs to fit snugly, getting precise measurements is crucial. I also considered clearance space around the unit for airflow and safety.

Heat Output and Room Size

I checked the heat output, usually measured in BTUs or watts, to ensure the insert could adequately warm my room. For smaller spaces, an 18 inch insert often provides sufficient heat. However, I kept in mind that electric fireplaces are generally supplemental heaters rather than primary heat sources.

Power Source and Installation

Most 18 inch electric fireplace inserts require a standard electrical outlet. I made sure there was a convenient power source nearby. Installation can be simple, often requiring just a plug-in, but some models might need minor modifications to the existing fireplace structure.

Features to Consider

I looked for adjustable flame brightness, multiple heat settings, and a remote control for convenience. Some units offer programmable timers and safety features like automatic shut-off if overheating occurs. These features enhanced my experience and added peace of mind.

Design and Aesthetics

Since the fireplace insert is a visible part of the room, I considered styles and finishes that matched my decor. The flame effect and log or ember bed options helped create a cozy ambiance. I also looked at the viewing angle and glass front clarity for the best visual appeal.

Energy Efficiency and Operating Costs

Electric fireplaces are generally energy efficient, but I compared power consumption rates to estimate operating costs. Using lower heat settings and flame-only modes helped me save energy when I just wanted the look without the heat.

Safety Considerations

Safety was a top priority. I chose inserts with cool-to-touch surfaces and built-in safety features. Since electric units don’t produce real flames or emissions, they are safer for homes with children or pets.

Budget and Warranty

I set a budget before shopping and compared options within that range. Considering the warranty and customer support was important in case of defects or malfunctions. A good warranty gave me confidence in the product’s quality.

Final Thoughts

Choosing the right 18 inch electric fireplace insert involved balancing size, heat output, features, and style. Taking the time to measure and consider my needs helped me find an insert that enhanced my living space both visually and functionally.
