Logs that glow from inside, and a heater with a second gear. Quick Facts • Heating Capacity: 250–500 sq ft• Viewing Area: 48″ x 18″ flame window.• Fuel: Electric.• Controls: Remote, touch panel, and app control.• Fan: Included Who It’s For Electric fires are easy to live with and hard to believe, and most give you a modest heater and no way to get more. You need the most convincing electric fire you can buy, with heat that can step up. If you want internally lit split oak logs, crackling sound, no-glare glass, and the option of a stronger heater on a 240-volt circuit, the Avita 48-inch is the one. A standard electric fire looks fine across the room and ordinary up close. What Makes It Special The Avita’s split oak logs are lit from inside and pulse with the fire, set in a crystalline ember bed behind premium non-reflective glass, so you see the fire and not your lamp, and a crackling sound setting finishes the illusion. Wired to a standard outlet it is a one-room heater; hardwired to 240 volts the heater nearly doubles. It installs single-sided with the included Edge+ frame, or as a corner or three-sided bay, and has a fan-only mode and flames with or without heat. Possible Downsides • The stronger heater requires 240-volt hardwiring, an electrician’s job; on a standard outlet it is a one-room supplemental heater.• No crystal media option; the Onyx offers crystals in place of logs. If you want the electric fire that fools people up close, the Avita 48-inch is the right decision. Guests lean in to check whether the logs are real. The Avita 48-inch comes with internally lit split oak logs and the Edge+ finishing frame, and offers an optional mood lighting system.
