Name: Amantii RusticStone Insert
Brand: Amantii
SKU: B0GPHVFRXQ

6.8Good · out of 10Rated from the listing's specs, no buyer reviews yet

The Amantii RusticStone Insert ticks most of the boxes we care about: a 10,000 BTU heater, app control and a flame that runs without the heat. It makes most sense for a living room where the fire comes on with the lights; we rate it 6.8/10 from its listing.

Heater output, per the listing

The heat the listing states. Plenty to take the chill off the room you sit in; how far it reaches depends on your insulation, windows and ceiling, and our supplemental heat planner turns your room into a rough answer.

What it has going for it

What changes in your evenings

10,000 BTU. Supplemental heat for the room you sit in: it takes the edge off a cold evening while the furnace stays turned down. Real coverage depends on your insulation, windows and ceiling height. Our supplemental heat planner puts it in numbers for your room.

App or WiFi control. Start the flames from the sofa or set a schedule from your phone, so the room is already glowing when you get home (as long as the house WiFi plays along).

Flame without heat. The heater and the flame run separately, so you can have the glow in July without warming the room. The fireplace earns its place all year, not only in January.

Living room or bedroom?

For the living room, the app or Alexa can start the fire before you are even home.

For a bedroom or a study, the timer switches it off after you fall asleep. The flame runs without heat, so it can glow on a warm night too.

On balance it is happiest in a bedroom, a study or a cosy corner.

Great for you if…

You want the chill off one room on cold evenings
You like to run the living room from your phone
You want the glow all year, heat or no heat

Skip it if…

You want the width stated up front: the listing we read gives no width
You want it to replace your heating: it is supplemental heat for one room
You'd rather wait for buyer reviews: none are captured for this listing yet

Our take

The verdict

On the Amantii RusticStone Insert, a 10,000 BTU heater is what caught our eye, and app control doesn't hurt either. No buyer reviews yet, so this Amantii built-in electric fireplace has to win you over on paper. The catch with the Amantii: no stated width in the listing, while most picks here give one. We'd pick it if you want the chill off one room on cold evenings; otherwise, put it next to the Sixfivsevn 36" Recessed and Wall Mounted first.

Living with it

Delivery day

A big, flat box with glass inside: open it with two people and check the front before the cardboard goes out.

The first evening

Try the flame at a few brightness settings; lower often looks more real at night. The 10,000 BTU heater takes the chill off the room you sit in.

Day to day

The remote on the sofa arm, the timer for bedtime, and a quick dust of the glass now and then. Our maintenance guide has the rest.

Summer

Heater off, flame on: the glow stays on the wall in July without warming the room.

The one thing we'd check first

One thing to settle before the Amantii RusticStone Insert ships: check the size, because the listing we read gives no clear width, and the size of your opening decides everything else.

Before you buy

Your wall

Measure the cavity or the opening (width, height and the depth the manual asks for) and hold it against the installation drawing of this exact model. Our recessed installation guide has the order.

The outlet

Pick the outlet before you pick the finish: a free one close by, nothing heavy on the same circuit, and no extension cord. Our power requirements guide lists the questions to ask.

Heat for your room

10,000 BTU stated. Treat it as supplemental heat for one room. Our supplemental heat planner turns your square footage into a rough answer.

Delivery and install

Glass-fronted inserts are big, flat boxes: plan two people for the unboxing, and decide early who frames the wall. Our built-in vs wall-mounted guide weighs recessed against wall-mounted.

Frequently asked questions

Is the Amantii RusticStone Insert any good?

We rate it 6.8/10 (good). The rating comes from its documented listing alone, as no customer-review record is captured yet.

What size and heater output does the Amantii RusticStone Insert state?

Its listing states a 10,000 BTU/h heater output and recessed (in-wall) installation. Those are the maker's figures, so check in the installation drawing whether the width means the frame, the firebox or the opening. Our supplemental heat planner puts 10,000 BTU/h in context for your room.

What power supply does the Amantii RusticStone Insert need?

The listing states 10,000 BTU/h. Read the supply, plug and circuit conditions on the exact listing and in the manual before you order, and never run a heater on an extension cord or a shared power strip. Anything beyond an existing standard outlet, hardwiring or 240 V included, is a job for a licensed electrician.

What do you get with the Amantii RusticStone Insert?

Its listing states a 10,000 BTU heater, app control, a flame that runs without the heat, logs and crystals to switch between and a timer. Those are the seller's figures; for how real the flames look in a living room and how loud the fan runs at night, the buyer reviews are the better guide.

What should I check before ordering the Amantii RusticStone Insert?

Your wall: measure the cavity or the opening (width, height and the depth the manual asks for) and hold it against the installation drawing of this exact model. Our recessed installation guide has the order. The outlet: pick the outlet before you pick the finish: a free one close by, nothing heavy on the same circuit, and no extension cord. Our power requirements guide lists the questions to ask. Heat for your room: 10,000 BTU stated. Treat it as supplemental heat for one room. Our supplemental heat planner turns your square footage into a rough answer. Delivery and install: glass-fronted inserts are big, flat boxes: plan two people for the unboxing, and decide early who frames the wall. Our built-in vs wall-mounted guide weighs recessed against wall-mounted.
