It is the mid-range model in the Virta Combi lineup - 9kW output that covers the majority of residential home sauna installations, combined with the full four-mode Combi sauna capability: traditional dry Finnish sauna, soft continuous steam sauna, herbal sauna with the included herb bag grate, and fragrance sauna with the dedicated soapstone cup for essential oil liquids. A Combi-specific external control unit (sold separately) and 100 lbs of Harvia AC3020 stones (3 boxes, 10-15 cm) are required for operation and are not included with this listing.\u003c\/p\u003e\n\u003ch4\u003e9kW Combi - the right size for most home sauna rooms with steam capability\u003c\/h4\u003e\n\u003cp\u003eThe HL90SA covers 177 to 494 cubic feet - the room range that encompasses the large majority of home sauna installations: standard 3 to 4-person rooms, high-ceiling sauna rooms, and rooms with glass or tile cold surfaces that push the adjusted cubic footage above the nominal volume. At 9kW it heats efficiently across the full range without the 10.5kW HL110SA's heavier stone requirement (100 lbs vs 150 lbs) or larger physical footprint. For buyers who have confirmed their sauna room is under 494 adjusted cubic feet, the HL90SA covers it at 9kW with the same full Combi feature set as the larger model. Only if the adjusted room volume exceeds 494 cubic feet does the HL110SA become necessary.\u003c\/p\u003e\n\u003ch4\u003eFour session modes - traditional, steam, herbal, and fragrance sauna\u003c\/h4\u003e\n\u003cp\u003eThe HL90SA's integrated steamer operates independently from the sauna heater, which is what enables the four distinct session modes. Traditional sauna mode runs the heater only and water is poured manually on the stones. Steam sauna mode runs both the heater and steamer simultaneously - the Combi control regulates temperature and humidity independently, so precise combinations from fully dry to high-humidity steam are achievable without manual water pouring during the session. Herbal sauna mode uses the stainless steel grate holder for aromatic herb bags, which release their fragrance gradually as rising heat passes through them. Fragrance sauna mode uses the integrated soapstone cup for sauna essential oil liquids, heating them gradually without direct contact between the oils and the heating elements - protecting the elements from corrosion and keeping the warranty intact.\u003c\/p\u003e\n\u003ch4\u003eStone space separated from elements - longer element life, front hatch service\u003c\/h4\u003e\n\u003cp\u003eThe HL90SA uses the same separated stone space design as all Virta heaters: the stone compartment surrounds the element assembly without pressing directly against it, which protects elements from direct water contact during loyly steam, keeps element operating temperatures lower, and produces faster preheat because heat distributes through the stone mass by convection. When an element needs replacing, the entire element module pulls out through the front maintenance hatch without moving a single stone. All wiring connections are accessible through the same front hatch. The HL90SA holds 100 lbs of AC3020 stones (3 boxes, 10-15 cm) - note the larger stone size (10-15 cm) versus the standard KIP\/Wall heaters that use AC3000 (5-10 cm).\u003c\/p\u003e\n\u003ch4\u003e5-litre integrated steamer - automatic or manual water filling\u003c\/h4\u003e\n\u003cp\u003eThe integrated steamer has a 5-litre water reservoir with two filling options. Manual filling is straightforward and requires no plumbing. Automatic filling connects the reservoir to a cold water supply line and maintains reservoir level automatically throughout the session. For permanent sauna installations where running a cold water line to the heater position is practical, automatic filling eliminates the need to check or refill the reservoir between sessions. Both methods produce identical steam quality. The Combi control manages the steamer output - humidity level is set independently from temperature and the steamer can run with the heater on or off.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sl-hook\"\u003e9kW floor-standing electric sauna heater with integrated steamer for rooms from 177 to 494 cubic feet.
