Details

The OKO S1 bioethanol stove in charcoal grey is a freestanding heating appliance that produces a real flame without the need for a chimney or flue. It is fitted with a stainless steel bioethanol burner and a tempered safety glass fronted door. The glass provides a clear view of the fire, while the handle-operated door allows safe access when required. The burner has a 1.5 litre capacity and provides a flame that lasts between 3 and 8 hours, depending on the fuel setting. Heat is distributed into the room through the airFLO convection system, and the stove is capable of producing up to 3kW of output. The supplied control tool is used to adjust the flame and manage the burn rate.

The OKO S1 stove operates on bioethanol fuel, which produces a flame without smoke, soot, or ash. This removes the need for cleaning or maintenance normally associated with wood or coal fires. With no chimney or flue required, the stove can be installed freestanding in a range of indoor settings. The body of the stove is finished in charcoal grey, giving it a solid appearance that suits a variety of interiors. The combination of glass, steel, and the open flame creates a simple but effective design, with functionality at its centre.

Delivery - What to Expect

Our standard deliveries arrive via a 10-tonne lorry (similar in size to a bin wagon or fire engine), equipped with a tail lift and pallet truck.
Access must be suitable: solid, level surfaces (no gravel, steps, steep slopes, or grass).
For palletised deliveries the driver will move the pallet to the nearest accessible point, but cannot go over unsuitable terrain or carry goods indoors, though may place them inside a garage if accessible.
If you have narrow gates, restricted access, or other challenges, please let us know in advance so we can make suitable arrangements.
Our free service is a one-man delivery. We recommend having someone available to assist, especially for larger items.
The delivery driver is not able to unpack or install your goods unless this is a service you have selected.

Checking Your Delivery

On delivery of your palletised goods, the driver will wait up to 10 minutes while you inspect the item(s).
Please check your goods before the driver leaves. If there is any damage or the driver refuses to wait, note this on the delivery slip (e.g., “Driver did not wait – damage unchecked”).
For any damage found, mark the delivery note clearly and contact us immediately.

Missed Deliveries

If you miss your pre-booked delivery, a re-delivery charge may apply.
For smaller items sent via courier (e.g., stove glass), the courier will leave a note with redelivery instructions if you’re not home.

Additional Delivery Notes

Accessory items like fitting kits and liner packs may be sent separately via courier on the same day. You’ll receive email confirmation if this is the case.
Delivery times are generally between 9am–6pm, Monday to Friday.
Delivery depots may send SMS updates, but these aren’t guaranteed.
