Harvia Legend 150SL Wood burning heater ( Black ) WK150LDSL

Experience the ultimate in sauna heating convenience and performance with the Harvia Legend 150 SL Wood Burning Sauna Heater, the through-wall variant of the acclaimed Legend 150 that allows the heater to be loaded and fired from an adjacent room or from outside the building -- keeping all wood, ash and debris entirely outside the sauna space. Sharing the same black steel frame, 16kW output and exceptional 120kg stone capacity as the standard Legend 150, the SL model adds the significant practical advantage of through-wall operation alongside a reversible cast-iron glass door for maximum installation flexibility. The result is a wood-burning sauna heater that delivers the authentic Finnish sauna experience with outstanding heat performance and genuinely spa-quality cleanliness within the sauna room itself. Handmade in Finland and CE and EAC certified, the Legend 150 SL is the definitive choice for those integrating a sauna with an adjacent utility room, changing room or outdoor space.

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 -- 120kg of 10 to 15cm stones are required and must be ordered separately.

Key features

• Through-wall firing from adjacent room or outside -- The defining feature of the SL model is its through-the-wall firebox extension, which allows the heater to be loaded and fired from an adjacent room or from outside the building entirely. Wood, ash and debris never enter the sauna space, creating a significantly cleaner and more refined sauna environment.
• Heats two rooms simultaneously -- The through-wall design means the Legend 150 SL can contribute heat to both the sauna room and an adjacent utility or changing room simultaneously, making it a highly efficient heating solution for integrated sauna installations.
• Reversible cast-iron glass door -- The SL's cast-iron glass door features a reversible hinge direction, providing additional installation flexibility to suit the specific layout and access requirements of your sauna and adjacent room configuration.
• Exceptional 120kg stone capacity -- The Legend 150 SL's high stone load absorbs and retains heat with exceptional consistency, maintaining a comfortable and even sauna temperature even as the fire burns down -- producing the soft, enveloping warmth that defines the finest Finnish sauna experience.
• 16kW output for saunas of 6 to 13 cubic metres -- With a 16kW output the Legend 150 SL is suitable for sauna rooms of 6 to 13 cubic metres, compatible with most home sauna cabins and larger integrated installations.
• Modern grate structure for cleaner burning -- The fire chamber uses a modern grate structure that separates combustion air, directing part of it to the upper section of the fire chamber for cleaner and more efficient combustion -- improving burn quality and extending the heater's lifespan.
• Reduced safety distances for flexible bench placement -- Reduced safety distances from the side and back surfaces to combustible materials allow greater flexibility in bench placement, making it easier to optimise the interior layout of your sauna around the heater.
• Adjustable legs for straightforward installation -- Adjustable legs make positioning the Legend 150 SL straightforward on variable surfaces, and the heater accommodates flexible flue connection options to suit your sauna room and building configuration.
• Compatible with optional pipe-mounted water heater -- The Legend 150 SL is compatible with an optional pipe-mounted water heater, providing an integrated solution for heating water alongside the sauna in the finest Finnish tradition.
• Handmade in Finland -- CE and EAC certified -- Every Harvia Legend 150 SL is handmade in Finland to Harvia's exacting quality standards and carries CE and EAC certification for complete peace of mind.

Legend 150 vs Legend 150 SL -- which is right for you?

The choice between the Legend 150 and the Legend 150 SL comes down to a single practical consideration -- where you want to load and tend the fire. If your sauna is a standalone cabin where loading the fire from inside the sauna room is perfectly acceptable, the standard Legend 150 is the right choice. If your sauna is integrated into a building with an adjacent utility room, changing room or outdoor access point, and you want to keep all wood and ash debris outside the sauna space, the Legend 150 SL is the definitive choice.

Beyond this distinction the two heaters are identical in every meaningful respect -- same 16kW output, same 120kg stone capacity, same modern grate structure, same adjustable legs and same handmade Finnish quality. The SL's additional depth of 730mm compared to the standard model's 530mm reflects the through-wall extension, and the reversible door hinge provides the additional installation flexibility that a through-wall configuration requires.

For those creating an integrated home sauna with a dedicated changing room or utility space alongside -- particularly those pairing the heater with the Harvia Legend sauna cabin -- the Legend 150 SL is an outstanding and highly practical choice that elevates the entire sauna experience.
