{"product_id":"oko-s1-bioethanol-stove-in-charcoal-grey","title":"OKO S1 Bioethanol Stove in Charcoal Grey","description":"\u003cp\u003eThe OKO S1 is a freestanding bioethanol stove in charcoal grey with a tempered glass door and a 1.5 litre stainless steel burner, giving up to 3kW depending on the opening. It needs no flue or chimney, so it can go in rooms where a wood or gas stove is not practical, and at 430 mm wide it is the most compact stove in the OKO range. You choose how it comes: with a shelf, on a log store base, with a decorative angled pipe (standard or tall), or on legs.\u003c\/p\u003e\n\u003ch2\u003eWhy choose the OKO S1\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReal flame from liquid bioethanol, with no flue or chimney\u003c\/li\u003e\n\u003cli\u003eUp to 3kW, set by the burner opening\u003c\/li\u003e\n\u003cli\u003e1.5 litre stainless steel burner\u003c\/li\u003e\n\u003cli\u003eCharcoal grey with a tempered safety glass door\u003c\/li\u003e\n\u003cli\u003eShelf, log store base or legs, with an optional decorative angled pipe on the shelf versions\u003c\/li\u003e\n\u003cli\u003eThe legs version is supplied fully assembled\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWill it suit your space?\u003c\/h2\u003e\u003cp\u003eIt needs a room of at least 63 cubic metres (length x width x ceiling height), and OKO treats the stove as a decorative heater, not your main heating. The room needs ventilation of at least 0.5 air changes an hour, which trickle vents, door gaps or briefly opening a window usually provide. As a rough heating guide, 1kW warms about 14 cubic metres, but a proper heat-loss check gives the right figure if you need it to heat the room. Stand it on a level, hard and stable surface, never on carpet. Every option is 430 mm wide and 300 mm deep; check the sizes table below for the height of each option.\u003c\/p\u003e\n\u003cdiv class=\"gf-sizes\" id=\"gf-sizes\"\u003e\n\u003ch2\u003eSizes and options\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth scope=\"col\"\u003eComes with\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eDimensions (H x W x D)\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eHeight with decorative pipe\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eWeight\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eBurner\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eShelf\u003c\/th\u003e\n\u003ctd\u003e570 x 430 x 300 mm (stove only)\u003c\/td\u003e\n\u003ctd\u003e830 mm (angled pipe), 1020 mm (log store and angled pipe), 1350 mm (log store and tall angled pipe)\u003c\/td\u003e\n\u003ctd\u003e16.3kg\u003c\/td\u003e\n\u003ctd\u003e1.5 litre stainless steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eShelf and angled pipe\u003c\/th\u003e\n\u003ctd\u003e570 x 430 x 300 mm (stove only)\u003c\/td\u003e\n\u003ctd\u003e830 mm (angled pipe), 1020 mm (log store and angled pipe), 1350 mm (log store and tall angled pipe)\u003c\/td\u003e\n\u003ctd\u003e16.3kg\u003c\/td\u003e\n\u003ctd\u003e1.5 litre stainless steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eShelf and log store\u003c\/th\u003e\n\u003ctd\u003e570 x 430 x 300 mm (stove only)\u003c\/td\u003e\n\u003ctd\u003e830 mm (angled pipe), 1020 mm (log store and angled pipe), 1350 mm (log store and tall angled pipe)\u003c\/td\u003e\n\u003ctd\u003e16.3kg\u003c\/td\u003e\n\u003ctd\u003e1.5 litre stainless steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eShelf, log store and angled pipe\u003c\/th\u003e\n\u003ctd\u003e570 x 430 x 300 mm (stove only)\u003c\/td\u003e\n\u003ctd\u003e830 mm (angled pipe), 1020 mm (log store and angled pipe), 1350 mm (log store and tall angled pipe)\u003c\/td\u003e\n\u003ctd\u003e16.3kg\u003c\/td\u003e\n\u003ctd\u003e1.5 litre stainless steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eShelf, log store and angled pipe (tall)\u003c\/th\u003e\n\u003ctd\u003e570 x 430 x 300 mm (stove only)\u003c\/td\u003e\n\u003ctd\u003e830 mm (angled pipe), 1020 mm (log store and angled pipe), 1350 mm (log store and tall angled pipe)\u003c\/td\u003e\n\u003ctd\u003e16.3kg\u003c\/td\u003e\n\u003ctd\u003e1.5 litre stainless steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eLegs\u003c\/th\u003e\n\u003ctd\u003e-\u003c\/td\u003e\n\u003ctd\u003e-\u003c\/td\u003e\n\u003ctd\u003e18.55kg\u003c\/td\u003e\n\u003ctd\u003e-\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"gf-desc-specs\"\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eOKO\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHeat output\u003c\/th\u003e\n\u003ctd\u003eUp to 3kW (set by the burner opening)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMinimum room volume\u003c\/th\u003e\n\u003ctd\u003e63m³\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFuel\u003c\/th\u003e\n\u003ctd\u003eLiquid bioethanol (above 90% alcohol) (Shelf, Shelf and angled pipe, Shelf and log store, Shelf, log store and angled pipe, Shelf, log store and angled pipe (tall)); Liquid bioethanol only (not suitable for gel fuel) (Legs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFinish\u003c\/th\u003e\n\u003ctd\u003eCharcoal grey with tempered safety glass door (Shelf, Shelf and angled pipe, Shelf and log store, Shelf, log store and angled pipe, Shelf, log store and angled pipe (tall)); Charcoal grey stove and legs; stainless steel burner (Legs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInstallation\u003c\/th\u003e\n\u003ctd\u003eFreestanding, no flue (Shelf, Shelf and angled pipe, Shelf and log store, Shelf, log store and angled pipe, Shelf, log store and angled pipe (tall)); Supplied fully assembled; place on a level, hard, stable surface (not carpet) (Legs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003c\/div\u003e\n\u003ch2\u003eInstallation and safety\u003c\/h2\u003e\u003cp\u003eNo flue, chimney or installer is needed.

Never leave it lit and unattended, do not use it in a kitchen or bathroom, and keep the control tool to hand to put it out.
