Description
The HUUM HIVE Wood LS is a 17 kW wood-burning sauna stove with a through-the-wall firebox extension, letting you stoke the fire from an adjacent room and keep the sauna itself calm and free of wood debris. It holds up to 130 kg of stones for a soft, long-lasting steam, and its most heat-stressed component, the flame tamer, is made from 5 mm stainless steel for exceptional durability. Suited to sauna rooms of 8–16 m³, it takes logs up to 400 mm long and connects to the chimney through a 115 mm flue. Sauna stones and the flue kit and chimney parts are sold separately; the same stove fired from inside the sauna is available as the standard HIVE Wood.

| Safety distance D | 2,240 mm |
| Min. clearance above stove | 1,200 mm |
| Fuel | Natural wood logs |
| Standard | EN 15821:2010 |
Installation
The stove connects to the chimney from its top outlet (115 mm diameter) using sealed metal flue pipes, and may only be connected to the chimney by a specialist. It requires its own dedicated flue of temperature class T600 with a minimum cross-section of 10,200 mm² and a minimum draught of 12 Pa; a shared flue with other appliances is not permitted. The firebox extension must pass through a non-combustible wall with at least 10 mm of air gap around the bushing, and if the floor in front of the furnace door is combustible it must be protected by a fire-resistant plate 600 mm wider than the door and at least 400 mm deep. Minimum clearances to combustible materials are 500 mm (A and B), 1,000 mm (C) and 1,200 mm above the stove; a single heat barrier halves these distances and a double barrier reduces them to a quarter. The stove stands on a non-combustible base at least 60 mm thick, and installation must follow the manual in the Downloads tab, EN 15821:2010 and local building regulations.
Sauna stones
The HIVE Wood LS takes up to 130 kg of stones, sold separately; any natural granite or purpose-sold sauna stones are suitable, while ceramic stones may shorten the life of the stove. Wash the stones before laying them.
Brand
HUUM is an Estonian maker of design-led sauna heaters and stoves, pairing minimal Nordic forms with smart sauna technology; its DROP heater won a Red Dot Award for product design in 2015.
