An electric fireplace does not legally need a hearth. It still needs one visually, and the floor under it usually needs one practically: heat, dust and the weight of a stove all leave a mark on a carpet that a slate pad prevents.
Electric Fireplace Hearth Kit at a Glance
- Honed slate, matt finish
- Eased edge
- Felt-backed base
- Three widths
- Protects carpet and timber
- No fixing required
Who it suits: a stove or insert standing on carpet, timber or tile where the floor needs protecting and the fireplace needs a base.
Why bother with a hearth
The pad defines the fireplace’s footprint. Without it, an insert or stove sits on a floor like a box that has been put down rather than a fireplace that was designed.
Honed slate is matt, so it does not reflect the flame into the room the way polished stone does. It reads warm and quiet, which suits both a period room and a modern one.
The eased edge stops the pad catching a foot or a vacuum cleaner, and the felt backing protects timber and tile.
Heating performance and room coverage
The element is a 1,500W fan-forced unit rated at 5,200 BTU. Outdoors that output does less than it does indoors, because warm air is lost to open space, and any product claiming otherwise at this price is overselling.
In practice a electric fireplace hearth kit 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 electric fireplace hearth kit 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 electric fireplace hearth kit in 42 inch, 48 inch, 54 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.
Slate and weight
A 48 inch pad weighs around 35 kg. On a suspended floor, keep it against an external wall where the joists are supported.
Sealing
Slate is porous. Seal it before the first winter if the pad is in front of anything that could spill; an unsealed pad stains permanently.
Level floors
A rigid pad on an uneven floor will rock. Check with a spirit level before you commit, and pack rather than force it.
Fitting an electric fireplace hearth kit
An electric fireplace hearth kit needs no fixing, which is the appeal. An electric fireplace hearth kit is heavy enough to stay put and felt-backed enough not to mark the floor beneath it.
Check the floor is level first. An electric fireplace hearth kit on a moving timber floor will rock, and a rocking pad cracks at the edge eventually.
Slate and an electric fireplace hearth kit
Seal it before winter. An electric fireplace hearth kit in honed slate is porous, and an unsealed spill becomes a permanent mark rather than a wipe.
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 is a freestanding stove rather than an insert, the same pad works: see the Standlow. For a surround above the hearth, the Hearthstone kit.
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
Is a hearth required?
Not for electric, but it protects the floor.
Can it go on carpet?
Yes, and it stops the insert sinking into pile.
Does it need sealing?
Recommended before use.
Can I cut it?
No, slate is supplied cut to size.
How heavy?
About 35 kg at 48 inches.
What sizes does it come in?
We stock it in 42 inch, 48 inch, 54 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 electric fireplace hearth kit 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.
