- Floor drain
- Harvia Virta Combi is listed as commercial grade in SaunaDesignPro.
- Virta Combi is part of the commercial-grade Harvia Virta set and adds a steamer, humidity sensor, cold-water shutoff/vacuum breaker, and floor drain requirements.
- Current Harvia US Combi rows list 2 in clearances; the local Virta Combi HL70S-HL110SA safety drawing also lists 30 mm around the heater and 1100 mm above the stones to the ceiling, so use the stricter listing/AHJ value where values conflict.
- Combi sensor placement follows the same sheet logic as standard Virta: a wall sensor above the heater 30-150 mm below the ceiling, moving to a ceiling-mounted sensor 100 mm out when the heater sits more than 150 mm from the wall.
- The Combi evaporator adds a 2.0 kW steamer rated at roughly 2.5 kg/h with a 5 L water reservoir: fill with clean household water before use, drain after every use, and follow the manual water-quality table; SA models support automatic filling.
- Combi HL80SA/HL90SA rows use 110 lb stones and HL110SA uses 154 lb; heating elements are separated from the stones and the stones should be rearranged during regular maintenance.
