If you’re building a large sauna and want a wood-fired heater specified for high output, the WK500’s 40 kW rating and 706–1766 ft³ recommended sauna volume range support that goal. The large specified stone load (264.6 lbs) is designed to help maintain stable heat and responsive steam in bigger rooms where smaller heaters can struggle to keep conditions even across multiple bathers and longer sessions.
From an ownership standpoint, the WK500 is defined by practical installation planning: floor mounting, back/top flue connection locations, and a listed 140 mm chimney connection diameter. Clearances and minimum room height are specified, helping builders design the room around the heater with fewer unknowns.
Harvia’s product lineup includes sauna heating products and related sauna equipment such as heaters, saunas, controls, and accessories, supporting owners who want a consistent approach to sauna system planning and long-term maintenance within an interior wet-area environment.
