Harvia Virta Pro HL160E Virta Pro Series 16.0kW Sauna Heater
The Harvia Virta Pro HL160E is a 16.0kW floor-mounted electric sauna heater for rooms from 354 to 918 cubic feet, designed and classified by Harvia as a professional-grade heater for heavy-duty use in spas, hotels, apartment buildings, and health clubs. The Virta Pro platform steps up from the standard Virta in two key ways: the heating elements are divided into two independent groups, each serviceable as a separate pull-out module through the front maintenance hatch; and the stone capacity increases to 200 lbs (5 boxes AC3020, 5-10 cm, sold separately). The two-group element design is the Virta Pro's defining structural feature - it allows the heater to be wired on two independent circuits (2x min. 16.7A each) for load balancing, and it means each element group can be serviced independently without taking the entire heater offline. A separate Xenio controller is required and sold separately. A Harvia power extension is also required for two-group wiring installations. 240V/1PH, 60Hz. ETL certified. Made in Finland by Harvia.
Virta Pro platform - professional-grade for heavy-duty and commercial use
Harvia classifies the Virta Pro explicitly for professional use - not just households. The HL160E is the 16kW configuration, suited for large sauna rooms from 354 to 918 cu ft in facilities where the heater runs multiple sessions daily across years of continuous operation. Harvia's description is direct: thanks to its strong construction, heating elements divided into two groups and exceptionally easy maintenance, the Virta Pro heater is an excellent choice for heavy-duty use. The Virta Pro steps up from the standard Virta Series in three ways - higher output at 16kW (vs the Virta HL90E's 9kW), a larger stone capacity (200 lbs vs 110 lbs), and the two-group element architecture that provides both wiring flexibility and independent serviceability that the standard Virta's single-group design does not offer.
Two-group elements - independent wiring and per-group serviceability
The most technically significant feature of the Virta Pro platform is the division of the 16.0kW heating elements into two independent groups. Each group can be wired on its own circuit - the heater can run on two separate 16.7A breakers rather than a single 25A circuit - which simplifies load balancing in commercial electrical installations and is a common requirement in apartment buildings and hotel facilities with dedicated circuit allocation per sauna room. Each element group is also a separate pull-out module accessible through the front maintenance hatch. If one group requires element replacement, only that group needs to be pulled out - the other group stays in place, and neither requires stone removal. For a heater in a commercial facility running multiple sessions daily, this is a meaningful operational advantage that reduces maintenance downtime compared to heaters requiring full stone removal for element access.
200 lbs of stones with front hatch access - soft steam and easy service
The Virta Pro HL160E holds 200 lbs (5 boxes AC3020, 5-10 cm) in an open stone cage with direct rock-to-element contact. The large stone mass stores substantial thermal energy during heat-up and releases it as soft, consistent steam throughout the session. Efficient air circulation through the open cage heats the sauna quickly. The front maintenance hatch gives access to both element groups and all wiring connections without touching the stones - every connection and every serviceable component is reached from one side of the heater. The stone cage is designed with efficient air circulation in mind: air moves through the stone bed in all directions, heating the stones evenly and distributing steam across the full stone surface when water is poured.

Why the Harvia Virta Pro HL160E stands out
Two independent element groups - commercial-grade architecture
The defining structural difference between the Virta Pro and the standard Virta is the division of the heating elements into two independent groups. This is not just a wiring option - it is a fundamental change to how the heater is serviced and powered. Each group is a separate physical module, wired independently, accessible independently through the front hatch, and replaceable without touching the other group or any of the stones. For a commercial facility where the heater runs daily and maintenance downtime has a real cost, the two-group design means element replacement can be done faster and with less disruption than with single-group heaters.
Two-circuit wiring - load balancing for commercial installations
The two-group element architecture allows the HL160E to be wired on two independent 16.7A circuits rather than a single 25A circuit. In commercial buildings - apartment buildings, hotels, health clubs - dedicated circuit allocation per sauna room often makes two smaller circuits more practical than a single large one. The two-circuit option also provides load-balancing flexibility: each group draws evenly from its own circuit, and either group can be isolated for service without shutting down the entire heater. A Harvia power extension is required for two-group wiring and is sold separately. A licensed electrician is required for all wiring.
200 lbs of stones - soft, abundant steam for large rooms
At 200 lbs (5 boxes AC3020, 5-10 cm), the Virta Pro HL160E carries the largest stone load in the Virta Series - nearly double the Virta HL90E's 110 lbs. The large stone mass stores significant thermal energy during heat-up and releases it steadily throughout the session. Steam quality is soft and consistent - the stones are heated evenly through direct rock-to-element contact and the open cage structure, so water thrown on any part of the stone surface produces the same quality of steam. For a 354-918 cu ft sauna room serving multiple bathers in rounds, the 200-lb stone load provides the thermal reservoir to sustain the session.
Front hatch maintenance - per-group access, no stone removal
The front maintenance hatch on the Virta Pro provides access to both element groups and all wiring connections without removing a single stone. Each element group is a pull-out module - accessed through the front hatch, disconnected from its circuit, and replaced as a complete unit. All connections have adequate space around them inside the hatch for a comfortable working environment. For a heater installed against a sauna wall with the minimum clearances, front-only access means no repositioning the heater for service. This is consistent with the Virta platform's design-from-day-one approach to maintenance - every aspect of the heater is accessible from the front without disturbing the installation.
Efficient air circulation - rapid heat-up for large rooms
The Virta Pro's open stone cage design allows air to circulate through the stone bed from multiple directions simultaneously. This air movement distributes heat through the stone mass evenly and rapidly, reducing the time needed to bring a 354-918 cu ft room to bathing temperature. Harvia specifically notes the efficient air circulation as enabling the sauna to heat up very quickly - a relevant capability for a commercial heater that may need to reach temperature between back-to-back sessions. The elements separate from the stones also means air is not blocked by element bodies within the stone bed, allowing more unobstructed flow through the full stone volume.
Virta Pro Series platform - HL160E and related configurations
The HL16U1UL is the 16.0kW 240V/1PH configuration of the Virta Pro Series. The same Virta Pro platform is available at 12.0kW (Virta Pro HL120E) for smaller large-room applications and at 20.0kW (Virta Pro HL200E) for the largest commercial sauna rooms. All Virta Pro models share the two-group element architecture, front maintenance hatch, separated element design, and professional-use classification. The Virta Pro is also available in a Combi configuration (Virta Pro Combi) that adds a built-in steamer for combined sauna and steam output. The standard Virta Series (HL60E, HL90E, HL120E) provides the same front hatch and separated element features at lower outputs for household use. Made in Finland by Harvia.
