Harvia Virta HL90E: a slim 9 kW sauna heater for rooms from 177 to 494 cubic feet
The Harvia Virta HL90E is a floor standing electric sauna heater made in Finland, with 9 kW of power for rooms from 177 to 494 cubic feet, enough for a roomy family sauna. It has the same slim black steel column shape as the rest of the Virta line. It measures 16 inches wide, 13 inches deep, and 33 inches tall, weighs 51 pounds empty, and can stand against a side wall or in a corner. The open top holds 100 pounds of stones on stainless steel heating elements for soft, even heat. The elements can be serviced.
The box holds the heater and its manual. It needs a Harvia Xenio wall control to run, and you add that on the page. Sauna stones are sold separately, so add the 3 boxes it needs on the page. A bucket and ladle set is optional. Heating a bigger room? The Harvia Virta HL110E sauna heater heats rooms up to 635 cubic feet. The Harvia Virta HL90E ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
FAQ
What size sauna is a 9kW heater right for?
The Virta HL90E is rated for sauna rooms from 177 to 494 adjusted cubic feet. Harvia positions the Virta line for medium to large saunas and for people who enjoy frequent, long sauna baths. Confirm your room’s adjusted volume against the installation manual linked on this page before ordering.
How many sauna stones does this heater need?
This heater requires a minimum of 100 pounds of sauna stones, which ship as the three stone boxes you select in the Required Stones option on this page — add them with your order. Because each natural stone is unique in shape and size, Harvia recommends an extra box so you can choose the best stones for fit, form, and function (additional freight applies).
How much electricity does it use per session?
It is a 9kW heater, so at full output it uses about 9 kilowatt-hours of electricity per hour of heating. To estimate cost, multiply your session hours by 9 and by your local electricity rate. Per the specifications table, the heater runs on 240V single-phase power at a nominal 37.5 amps.
Do I need to buy a separate control unit?
Yes. The heater has no built-in controls and requires a Harvia Xenio digital control for operation. The required control is listed under Required: Sauna Heater Controls on this page, so you can add it to the same order as the heater — the listed Xenio unit is a digital control with WiFi.
Where are these sauna heaters made?
Harvia designs, engineers, and manufactures this heater in Finland, and the brand has been building heaters for over 70 years. Construction is stainless steel, including heating elements Harvia describes as industrial grade and serviceable. You can compare it against the store’s other electric sauna heaters from the same category page.
What's included in the box, and what warranty applies?
The package includes the sauna heater and the installation and operation manual, and the heater carries a 2-year warranty for consumer use. The Xenio control and sauna stones the heater needs are selected as add-ons on this page. Full warranty terms are in the Harvia warranty document linked near the top of this page.
