Media wall · feature wall · Calgary

The fire in the wall you're already building.

Three Optimyst formats frame into a media wall: the Linear (46, 66 or 86 in, with a heater), the glass-fronted Pro Box (40 or 60 in, single-sided or see-through), and the plumbed, flame-only e-MatriX (35 in, front, corner or bay). We design the chase, the air, the water and the power into the wall, then build the wall.

What goes in

Three formats, one decision each.

Heat and width point to the Linear. A glass front, a see-through wall or a drafty room point to the Pro Box. A flame-only, plumbed, corner or bay opening points to the e-MatriX. The middle size of each is shown; the comparison table has all nine.

How it's built. Section through the wall with a Linear. The unit sits in a chase 12 in deep with its bottom 5 to 50 in off the floor; the flame trough is open to the room. Air comes in near the floor and rises to the unit; water (blue) comes up the chase; wiring enters top-right rear. The TV hangs above a clear zone. The e-MatriX and Pro Box change the depth and the front (glass), not the idea. All figures are Dimplex's.

The job

The wall, the services, the fire.

A media wall with a water-vapour fire is a normal media wall plus three things: a real air path, a water method, and a chase deep enough. We plan those first and the finish second, so nothing gets closed up wrong.

  • The drawingElevation and section of the wall with the unit, TV, mantel, air grille, water and power marked, and the finish called out. You approve it before framing.
  • The framingA chase to the unit's framing table (12 in for the Linear, 21 in for the e-MatriX, the Pro Box confirmed from its manual), not load-bearing, with the drywall opening exactly as the manual draws it.
  • The airA fresh-air inlet near the floor with a continuous path up to the underside of the unit: 80, 120 or 160 in² for the Linear by size, 80 in² for the e-MatriX, larger if a grille covers it. Hidden in a plinth or a slot.
  • The waterA 1/4 in cold line up the chase through a shutoff, a leak-detection valve and a softening cartridge (Dimplex's plumb kit), or a reservoir with an access door on the Linear and Pro Box. The e-MatriX is plumbed always.
  • The powerAn electrician runs the circuit: 240 V for full heat on the Linear (the 86 in gives no heat on 120 V), 120 V otherwise, dedicated 15 A, permit included. TV outlet and cable route while the wall is open.
  • The finishDrywall and paint, slat panels, large-format tile, stone veneer, a floating mantel, shelf lighting: whichever the drawing shows, built to the manual's overhang rules around the opening.
  • The fireUnit set, wired, plumbed or filled, media placed, remote and app paired, flame and heat tested, then a walkthrough of the clean and the controls.
  • Your own contractor?Then we supply the unit at list price, hand over the planning sheet, check the framing before it closes, and set and commission the fire. The wall stays their work and their price.

Before you decide

What a water-vapour media wall asks of you.

  • The wall gets deeper.

    Twelve inches for the Linear, twenty-one for the e-MatriX. That is a chase or a bump-out, not a flat wall, and it is why we draw the room before we quote.

  • There is a grille somewhere near the floor.

    Every unit needs its fresh-air path. We hide it in a plinth, a shadow line or a slot, but it exists, and it stays clear of rugs and furniture.

  • Plumbed is the sane choice in a wall.

    A reservoir behind a finished wall means an access door and a jug every so often. A 1/4 in line up the chase during construction is a small job and you never think about water again. The e-MatriX gives you no choice; it is plumbed.

  • Full heat on the Linear means 240 V.

    On 120 V the 46 and 66 heat at reduced output and the 86 does not heat at all. If warmth matters, the electrician runs 240 V while the wall is open.

  • The Pro Box is new for 2026.

    Its price and overall size are on the list; its own manual is not on file yet. We confirm framing, air and electrical from Dimplex before we frame around one, and we say so on the quote.

  • The TV goes above, on the TV's terms.

    Dimplex's rule for the heated units is the TV maker's over-heater rule. We plan the height, or a mantel break, on the drawing, and we keep open air directly above the flame.

  • Drafts flatten it.

    A register blowing at the wall or a door that stays open will push the flame around. If the room is drafty, the glass-fronted Pro Box is the right unit, and Dimplex says so.

  • It needs a clean.

    The reservoir and transducers get a wipe with soap and water at the interval in the unit's manual, and the softening cartridge gets changed a few times a year. Plumbed with softened water is the lightest version of this.

Send a photo of the wall.

Straight on, from where the couch is, with the wall width and ceiling height if you know them. You get the picture back with the fire in it, plus a range for the wall. Usually within a couple of days.

  • Take one photo of the wall, opening, counter or corner from where you usually sit. Phone is fine.
  • We place the right unit for your depth, water and heat answers and send the picture back, labelled as a concept.
  • You get a rough price: the unit at list price, the build as a range, and what a site visit would confirm.

Questions

Questions people ask about media walls.

Can the TV go above a water-vapour fireplace?

Usually, planned properly. For the heated units (Linear, Pro Box) Dimplex's rule is the television maker's own rule for mounting over a heater; the heat vents at the front, not up the wall. On every unit the vapour rises a short way above the flame and dissolves, so we keep a clear zone above the flame and set the TV height, or a mantel break, at the design stage. The e-MatriX has no heater at all.

How deep does the wall need to be?

The Linear frames 12 inches deep, the Pro Box is 16-1/4 inches deep overall (its 2026 framing figure is still to be confirmed from Dimplex's manual), and the e-MatriX frames 21 inches deep. So a standard 2x4 or 2x6 wall is not enough on its own: the fire goes in a chase or a bump-out, which is what a media wall is anyway. The wall also needs a fresh-air inlet near the floor with a clear path up to the unit.

Which of the three heats?

The Linear has a fan heater (Comfort$aver, with Eco and Boost modes); wire it 240 V for full output, and note the 86-inch gives no heat at all on 120 V. Dimplex describes the Pro Box with a fan heater too; we confirm the 2026 box's rating before promising it. The e-MatriX is flame only.

Do I have to plumb it?

The e-MatriX, yes: it is designed for a direct water connection. The Linear and Pro Box run from a reservoir you fill or from Dimplex's plumb kit on a cold line. In a wall we recommend plumbed, because a reservoir behind a finished wall means an access door and a jug; a 1/4 inch line up through the chase is simple during construction. Either way there is a shutoff you can reach.

Can I replace the electric or gas fireplace already in my wall?

Often. The existing opening rarely matches an Optimyst's framing, so the wall around it gets rebuilt: new framing, the air path, water and power, and the finish. If it is a gas unit, a licensed gas fitter caps the line and the vent is dealt with. It is quoted like a new wall, sometimes a little more because of the tear-out.

Can it be see-through?

The Pro Box takes a rear glass pane (on the price list, $440.99 for the 40 inch and $827.99 for the 60 inch) for a see-through wall between two rooms. The Aura and the e-MatriX bay open on three sides for a half wall; that is the half-wall page.

Do you build the whole wall or just the fireplace part?

Either. If you have a contractor building the wall, we supply the unit, hand them the planning sheet, check the framing before it closes up, and set and commission the fire. If you don't, we design and build the wall: framing, finish, TV position, cable routes, lighting, mantel. The price range on this page is for the second case.
