A three sided fire is an architectural object rather than a wall appliance. It sits in a pier or a divider, and the flame can be seen from three directions at once.
Three Sided Electric Fireplace at a Glance
- Glass on front and both returns
- Built into a pier or divider
- 5,200 BTU heater with thermostat
- Fits 48 and 60 inch spans
- Log bed with ember glow
- Remote, timer, flame-only mode
Who it suits: an open-plan room where the fire sits in a divider and is seen from three directions.
Where three sides earn their cost
Open-plan rooms divided by a half-wall, a structural pier, or a media unit that turns a corner. Anywhere people sit on more than one face of the fire.
The returns carry the glow around the corner, so a room that is partly behind the fire still gets light. That is the detail a single-sided unit cannot fake.
It needs a framed box rather than a pocket: 12 inches deep, square on three faces, with the wiring reached from the service side.
Heating performance and room coverage
Heat comes from a 1,500W element rated at 5,200 BTU, on a standard 15 amp circuit. Outdoors, placement matters more than output: a unit aimed at the seating beats a bigger unit aimed at the sky.
In practice a three sided electric fireplace holds 400 to 600 square feet comfortably, and helps in a room up to about 1,000 square feet when the doors are shut and the walls are insulated. Placement matters less than most buyers expect, provided the outlet is not blocked, and the thermostat does the rest of the work.
The flame runs independently of the heater. Turn the heat off and the fire becomes lighting, which is how most people use it for eight months of the year.
The most common mistake with a three sided electric fireplace is buying it for the whole floor plan rather than the room you sit in. Match the unit to the room and the thermostat will cycle calmly instead of running flat out all evening.

Where it goes outdoors
Under a roof, facing the seating. That is the rule that decides whether an outdoor fire gets used or gets ruined. A pergola, a porch ceiling, a balcony above or a carport all count. Open sky does not.
Wind matters more than temperature. Place the unit so its outlet runs across the seating rather than into the prevailing breeze, and put a screen, a planter or a wall on the windward side if you can. A 5,200 BTU fire in a breeze loses most of its output.
Keep 20cm above and 30cm below the unit, and keep anything flammable clear. A __KW__ near a stack of cushions or a folded parasol is asking for trouble, and outdoors people store things in exactly those places.
Finally, site it near a weatherproof socket with an RCD or GFCI on the circuit. An extension lead across wet paving is the one genuine hazard in this category, and an outdoor socket costs less than the fire.
Running costs outdoors
Full heat draws 1.5 kWh an hour. At the US average of about 15 cents per kWh, that is roughly 22 to 23 cents an hour.
Compare that with a gas patio heater, where a 15kg cylinder lasts around ten hours and heats a radius whether or not anyone is sitting in it. Running one electric fire over one seating group is cheaper as well as more targeted.
Flame-only mode draws a few watts, so a summer evening of light costs pennies. Most owners run it that way from May to September and use the heat for the shoulder months only.
The Department of Energy explains how resistance heating is priced per kilowatt hour. Ten minutes there will save you guessing at running costs.
Installation without a trade
There is no flue, no gas and no vent, so a standard install needs no qualified fitter and no inspection afterwards.
- Measure both corner returns and check the unit clears every skirting board and window return before you unpack it.
- Move it into position with two people. Corner units are awkward rather than heavy, and one person will inevitably twist the frame trying to lift it alone.
- Level the feet against both walls. A corner out of square is normal; adjustable feet take up 12mm, which covers almost every room.
- Route the cord to the nearest outlet, keeping it behind the base rather than across the floor where it collects dust and gets kicked.
- Run the flame for ten minutes, then heat on low for five, then full output. If anything rattles at full heat, stop and call us.
The whole job takes about thirty minutes. If you are wall-mounting rather than placing a freestanding unit, add twenty minutes for the brackets.
Choosing the right size
We stock this three sided electric fireplace in 48 inch, 60 inch. All options share the same body height, so the decision is about width rather than height.
Start from the wall. If the usable span is under 45 inches, choose a smaller body; a wide unit in a short wall crowds the doorway and looks wedged in rather than fitted.
Then look at the room. A 400 square foot room suits any size, while a 600 square foot open-plan space benefits from the wider option, because heat leaves a wider outlet and the flame fills more of the corner.
If you are between sizes, go up. Buyers who regret a corner fireplace almost always regret buying small.
Care and safety
Wipe the glass with a non-ammonia cleaner and a microfibre cloth, only when the unit is cool. Hot glass and cold cleaner is how crazing starts, and no polish fixes it afterwards. It is the only maintenance a __KW__ really needs.
Dust the frame monthly. Matte finishes show dust in side light, and gloss finishes show fingerprints; both are handled by the same dry cloth.
Vacuum the intake grille every few weeks and keep fabric clear of it. The overheat cut-off protects the unit, not your evening. On a __KW__, the intake sits at the top of the body, where a curtain or a shelf can block it without anyone noticing.
Check the plug and cable once a year. A wall fire is often plugged in behind furniture, where a loose plug goes unnoticed for a decade.
What ownership looks like in year three
No fuel, no ash, no flue and no sweeping. The running cost is electricity and the maintenance is glass and dust.
The LED flame is rated for tens of thousands of hours, which is years of daily evening use. If an element fails inside the 12 month warranty we replace the unit rather than sending you a part and a diagram. That applies to every __KW__ we sell, whatever the size.
The finish is what ages. Matte black keeps its colour; pale and gloss finishes show the years. Cleaning with warm soapy water rather than abrasives is the whole secret, and it takes about a minute a month to keep a __KW__ looking new.
Returns run 30 days on unopened units. Keep the carton for a week after delivery and photograph the glass before you recycle the packaging.
Three mistakes to avoid
Buying for the room, not the wall. A __KW__ heats 400 to 600 square feet. Buy it for a bigger space and you will spend the winter disappointed by arithmetic rather than by the product.
Mounting it too high. Forty-eight inches to the centre is the height that works. Anything much above eye level turns a fire into a picture and puts the glow over people’s heads.
Sharing the circuit. At full heat these draw 12.5 amps. A kettle or a second heater on the same circuit will trip the breaker, and the fire will get the blame.
Framing the pier
The box has to be square on three faces, because any twist shows in reflections. Build it from 2×4 and cement board, check with a level, then board and skim.
Heat distribution
The heater faces the main side. The returns give light, not warmth, and that is the honest expectation to set before installation.
Cleaning three panes
Three surfaces means three lots of fingerprints. Clean them cold, monthly, and use the same non-ammonia cleaner on all of them.
Living with a three sided electric fireplace
A three sided electric fireplace is an object in the room rather than an appliance on the wall. In an open-plan house, a three sided electric fireplace in a divider gives two or three seating areas the same fire.
The returns carry the glow around corners. A three sided electric fireplace lights a hallway that a single-sided unit would leave dark.
Framing a three sided electric fireplace
It needs a 12 inch box, square on three faces. A three sided electric fireplace shows any twist in the frame, so check with a level before boarding.
Delivery, returns and the two things people ask about
Everything ships from our own yard, tracked, in 2 to 5 business days. Shipping is a flat $50 under $1,000 and free over $1,000, with a $150 minimum order. We will not promise a delivery window we cannot hold, and if a carrier loses a unit we replace it rather than sending you to a claims form.
Returns run 30 days on unopened units. Keep the carton for a week after delivery, because a transit scuff is far easier to resolve while the packaging still exists. Photograph the glass in daylight before you recycle anything.
Two questions come up on almost every order. The first is whether the heater can run without the flame, and it cannot: the flame is the light source for the fire and it stays on whenever heat is on. The second is whether the flame can run without the heater, and it can, all year, which is how most owners use these units from spring onwards.
How it compares to the rest of the range
If the fire only faces one room, the Onyx black glass is far cheaper to install. For a corner where two faces would do, a curved panel holds the flame from an angle.
The Ember Peak standard
Every fire we ship is bench-tested before it leaves the yard. We inspect the flame with the heater off, check the thermostat, and test the cord and plug, because a fireplace that arrives with a rattle is one you resent for years.
Delivery arrives tracked within 2 to 5 business days. Shipping is a flat $50 under $1,000 and free over $1,000, with a $150 minimum order. Anything unclear before or after the sale reaches a human on the contact page, and we will tell you when a different model suits your wall better.

Common questions
Does it heat all three sides?
No, the heater faces the front; the returns give light.
Does it need a chimney?
No.
Can it sit in a normal wall?
It needs a 12 inch framed box.
Is the glass safe?
Tempered, and warm to the touch when lit.
Can it be surface mounted?
No, it is a built-in.
What sizes does it come in?
We stock it in 48 inch, 60 inch. All sizes share the same body height, so choosing one is a decision about width.
Does it include a remote and timer?
Yes. The box includes a remote, an adjustable thermostat, a 1–9 hour timer and the fixings.
If you are replacing an open fire or a gas fire that no longer works, this three sided electric fireplace is the least disruptive route back to a working hearth. Nothing structural changes, nothing needs sweeping, and the whole job takes under an hour.
Every unit ships from our own yard rather than a third-party warehouse, which is why we can tell you honestly what fits your corner and what does not. We would rather talk you out of the wrong size than sell you one and post you a returns label.
