Dimplex Optimyst 86" Linear Water Vapor Electric Fireplace
Description
Overview
Seven feet of flame made from water vapor and light
The Optimyst Linear works differently from an LED fireplace. An ultrasonic system turns water into a fine mist, and multi-colored LEDs light it from within, so the "flame" has real three-dimensional movement and a smoke-like drift you can see from any angle. Adjustable spacers let you shape the flame, and crackling wood sound rounds out the effect. At 87-1/2" wide, this is the largest size in the range — scaled for a great room or a lobby wall.
It also heats: a fan-forced heater with Eco Heat and a 15-minute Boost mode warms spaces up to 1,000 sq ft, and an Air Circulation Mode moves room air without heating. The flame runs with the heat off, so you can use it year-round — useful at this scale, where the fireplace is on for the look far more often than for warmth.
Before you buy — two things to plan: this unit is direct-wired to a 120V or 240V circuit (a 120V plug kit is available separately), and it's designed to be hard-plumbed to your water line with 1/4" tubing for continuous operation — worth planning at this size, since manual filling gets old quickly. An overflow sensor shuts off the water supply automatically. Ask us about the plumbing kit and plug kit before you order and we'll quote them with the fireplace.
What's included: the firebox, lifelike driftwood logs, acrylic ice media, and a multi-function remote. Not included: the electrical circuit, plumbing connection, plug kit and plumbing kit.

Water, Warranty & Upkeep
A water-vapor fireplace needs a little care that an LED unit doesn't: the water type your unit should run on, and the cleaning interval for the transducer and water tank, are set out in the Dimplex owner's manual. Ask us before you order and we'll send you the manual and the current warranty terms for this model, so you know exactly what ownership involves.
As your authorized dealer, Lumiflares files any warranty claim on your behalf — we source parts and manage the process with the manufacturer. Keep your proof of purchase, model number, and serial number.
FREE Shipping on Every Order
Free curbside shipping on all orders. Free liftgate service included. At over 7 feet this is oversized freight — plan for help moving it from the curb.
