Overview:
- The Flex 50SS is the first size in the Flex Single Sided range to offer an integrated log-storage box alongside the full-width All Flame opening, a configuration choice rather than a separate product. At 1470mm wide on the XL900 burner in All Flame form, it’s built for a genuine feature wall.
Design & Build:
- Zinc-sealed mild steel surround and toughened glass, available in three configurations at the same price: All Flame (full-width XL900 burner, 15,000 BTU/h from a 9-litre tank), or with an integrated log-storage box built into the left or right side of the opening (XL500 burner, 11,430 BTU/h from a 5-litre tank, with the freed-up width holding a stack of decorative logs behind glass rather than flame). The burner is available in Stainless Steel as standard, or a Black ceramic-coated finish for a flat, monochrome look, at a fixed premium.
What it does well:
- All Flame runs 8 to 13 hours per fill and heats a 110m³ room; the log-box configurations trade some of that output (11,430 BTU/h, 80m³) for a genuine styling detail, at no extra cost. All three share the same 1470mm frame and 807mm height, so the choice is purely about which look suits the room.
Trade-off worth knowing:
- Choosing a log-box configuration means living with less flame width and heat output than All Flame for the same money, a styling trade rather than a free upgrade. If maximum heat output matters more than the log detail, All Flame is the one to pick.
