Harvia Linear 18 Compact Wood Burning Sauna Heater | WKLI18CPTM

Combine style, space efficiency and advanced engineering in your sauna with the Harvia Linear 18 Compact Wood Burning Sauna Heater, a beautifully resolved black wood-burning heater designed for small to medium-sized sauna rooms of 5 to 18 cubic metres. The Linear 18 Compact's double-shell structure keeps surrounding wall structures cool and requires only 92mm of safety distance from the sides, making it one of the most installation-flexible wood-burning sauna heaters available and ideal for sauna rooms where space around the heater is limited. The large glass hatch highlights the clean-burning fire and creates a warm, cosy glow within the sauna interior, whilst the advanced airflow design ensures the room heats up quickly and efficiently. CE, BImSchV 2 and EAC certified and handmade in Finland, the Linear 18 Compact meets modern emission and efficiency standards without compromising on authentic Finnish sauna performance.

At Home of Clay we are proud stockists of Harvia, one of the world's most respected sauna manufacturers. Please note that stones are not included -- 10 to 15cm stones must be ordered separately up to the 40kg maximum capacity.

Why choose the Harvia Linear 18 Compact?

The Linear 18 Compact addresses one of the most common practical challenges in wood-burning sauna heater installation -- safety clearance distances. Many wood-burning heaters require significant clearance from surrounding walls and combustible materials, which can severely limit bench placement and interior layout options in smaller sauna rooms. The Linear 18 Compact's double-shell structure and 92mm minimum safety distance from the sides transforms this situation, allowing much more flexible positioning of the heater within the sauna room and freeing up valuable bench space that a conventional heater would require to remain clear.

The BImSchV 2 certification is a meaningful differentiator for those who are mindful of the environmental performance of their heating appliances. This German emissions standard is one of the most stringent for solid fuel burning appliances in Europe, and its presence on the Linear 18 Compact confirms that the advanced airflow design delivers not just rapid heating and clean combustion in the practical sense but measurably lower emissions than many comparable wood-burning sauna heaters.

For those creating a small to medium home sauna where space efficiency, clean combustion and genuine Finnish quality are equally important, the Harvia Linear 18 Compact is an outstanding and thoroughly modern choice that does not compromise on the authentic wood-burning sauna atmosphere that makes the experience so special.
