What Is a Double Sided Electric Fireplace?
A double sided electric fireplace—also called a see-through or two-sided electric fireplace—is a single unit with a transparent firebox that shows flames from both the front and the back. Unlike traditional masonry fireplaces, it does not burn wood, gas, or ethanol. Instead, it uses LED lighting and a reflective mechanism to create a realistic flame effect, paired with an electric heater that blows warm air into the room.
Because it is electric, this type of fireplace requires no chimney, no venting, and no gas line. That makes it remarkably flexible for placement. You can install it in a room divider, a shared wall between a living room and a dining area, or even in a covered patio wall where it faces both an interior space and an outdoor lounge.
If you are still weighing fireplace technologies, our guide to fireplace types and the electric vs gas vs wood comparison can help you understand where electric models fit best. For a broader foundation, the beginner's guide to fireplaces is a useful starting point.
Why Choose a See-Through Electric Fireplace?
Double sided electric fireplaces solve several problems that single-sided units cannot. They act as a visual bridge between two spaces, they double the flame viewing area, and they eliminate the need for a chimney or complex installation. Here are the main advantages:
Key Benefits
- Two rooms, one fireplace: Enjoy the ambiance from both sides without buying two units.
- No venting or chimney: Ideal for apartments, basements, and modern homes without existing flues.
- Indoor and outdoor flexibility: Many models are rated for covered outdoor use, extending your living space.
- Low maintenance: No ash, no soot, no creosote. Cleaning is limited to dusting and occasional glass wipe-down.
- Design versatility: Perfect for room dividers, shared walls, and open-concept layouts.
- Safe operation: No open flame, no carbon monoxide, and cool-to-the-touch surfaces on many models.

Indoor vs Outdoor Use: What You Need to Know
Not every double sided electric fireplace is built for outdoor exposure. The key factor is the IP (Ingress Protection) rating. An IP rating tells you how well the unit resists dust and water. For a covered patio or screened porch, look for a model with an IP rating that indicates protection against splashing water and dust.
Even with a suitable IP rating, an outdoor electric fireplace should always be placed in a covered area. Direct rain, snow, and prolonged humidity can damage the electronics and the finish. A covered patio, pergola, or screened porch is ideal.
If you are planning an outdoor installation, our outdoor fireplace maintenance guide and the screened porch electric fireplace page offer practical tips. You may also want to review whether all fireplaces need a chimney to confirm your setup is viable.
| Feature | Indoor Use | Covered Outdoor Use |
|---|---|---|
| Venting required | No | No |
| IP rating needed | Not critical | Recommended |
| Moisture protection | Standard | Essential |
| Heating role | Supplemental | Supplemental |
| Installation complexity | Low | Low to moderate |
How to Choose the Right Double Sided Electric Fireplace
Choosing the right unit comes down to four factors: size, heating capacity, placement, and style. Because there is no venting or fuel type to worry about, you can focus on how the fireplace will look and how much warmth you need.
1. Size and Viewing Area
Double sided electric fireplaces range from compact 30-inch units to large 60-inch or wider models. The viewing area on each side is typically half the total width, so a 60-inch unit gives you roughly 30 inches of flame view per side. Measure your wall opening carefully and consider how the fireplace will look from both rooms. Our guide to matching fireplace proportions to room shape can help.
2. Heating Capacity and BTU
Most double sided electric fireplaces produce between 4,000 and 5,100 BTU, which is enough to take the chill off a room but not enough to replace a central heating system. Use our heating capacity and BTU guide to estimate what your space needs, and check whether a fireplace can heat an entire house for realistic expectations.
3. Placement and Installation
Double sided electric fireplaces are usually built into a wall or partition. Some models are designed for recessed installation, while others can be wall-mounted or freestanding. If you are installing one yourself, our plug-and-play electric fireplace installation guide and DIY vs professional installation comparison will help you decide. For a freestanding alternative, see built-in vs freestanding fireplaces.
4. Flame Realism and Features
Flame quality varies significantly between entry-level, mid-range, and premium models. Higher-tier units typically offer more realistic flame effects, adjustable flame colors, crackling sound, and better remote or smart-home controls. If realism matters to you, explore our articles on the most realistic freestanding electric fireplace and most realistic wall-mounted electric fireplace.
Double Sided Electric vs Other Two-Sided Fireplaces
Double sided fireplaces are also available in wood-burning and gas versions. Each has trade-offs. Electric models are the easiest to install and the safest for indoor-outdoor use, but they produce less heat than gas or wood. Gas models offer stronger heat but require a gas line and venting. Wood-burning models provide the most authentic experience but need a chimney, regular cleaning, and more maintenance.
If you are curious about the alternatives, see our pages on the two-sided wood burning fireplace, the double sided wood burning indoor outdoor fireplace, the indoor outdoor see-through wood burning fireplace, and the wood stove insert for double sided fireplace. For gas options, the double sided gas fireplace insert with blower is a relevant reference.

View RecommendationsInstallation and Maintenance Tips
Installation of a double sided electric fireplace is relatively straightforward, but a few details matter. First, confirm the wall cavity is deep enough for the unit's chassis. Second, ensure there is a nearby power outlet, or plan for a hardwired connection if the model supports it. Third, if installing outdoors, verify the unit's IP rating and place it under a roof overhang or in a screened area.
Maintenance is minimal. Dust the unit regularly, clean the glass with a non-abrasive cleaner, and inspect the power cord and plug for wear. For a complete routine, see our electric fireplace maintenance guide and cleaning electric fireplace article. If you notice issues like unusual noise or a non-working flame, our electric fireplace troubleshooting section covers common fixes, including flame not working and not heating problems.
Frequently Asked Questions
Can a double sided electric fireplace be used both indoors and outdoors?
Many models are designed for dual indoor and outdoor use, provided they are placed in a covered area protected from direct rain and moisture. Always check the product's IP rating before installing outdoors.
Does a double sided electric fireplace require ventilation?
No. Electric fireplaces do not produce smoke or harmful gases, so they require no chimney, flue, or venting. This makes them ideal for apartments, basements, and spaces without existing ductwork.
How much space does a see-through electric fireplace need?
A double sided electric fireplace needs a wall or partition thick enough to house its body, typically around 6 to 12 inches of depth. It is commonly installed in a freestanding wall, room divider, or shared wall between two rooms.
Can a double sided electric fireplace heat two rooms at once?
It can distribute ambient warmth to both sides, but the heating output is shared. For larger rooms, it works best as a supplemental heat source rather than a primary heating system.

Final Thoughts
A double sided electric fireplace indoor outdoor unit is one of the most flexible and design-friendly fireplace options available. It delivers ambiance to two spaces at once, requires no venting, and can be safely used in covered outdoor areas when the IP rating allows. Whether you are dividing a living room from a dining area or connecting an indoor lounge to a patio, a see-through electric fireplace is a smart, low-maintenance choice.
