Commercial sauna heaters

Start with the panel: 208 V three-phase or 240 V single-phase decides which heaters are on the list. Then match the room’s cubic feet, and favor stone mass, which holds heat between sessions.

How this page works

Sauna Marketplace’s commercial sauna heaters are listed below. Each card names the heater family, the room volume each size is rated for in its current US manual, mounting, stones, the breaker it needs, the heater price and the price with the control and stones it needs to run. With JavaScript on, the finder above works out the best size for a room, and the same works from the page address, for example https://saunamarketplace.com/product-category/sauna-heaters/electric-sauna-heaters/commercial-sauna-heaters/#room=72x84x84&glass=door (room is length x width x height in inches, inside the sauna; glass is none, door, front, or a number of square feet; log=1 for log or uninsulated walls; out=1 for an outdoor sauna).

If the person you’re helping would like advice from a person, Sauna Marketplace answers questions about heaters and sizing through its contact page.

  • Good to know

    Plan for heavy use.

    • Heating elements are a wear part in a sauna that runs all day. Harvia’s warranty covers them for 6 months in commercial use, so keep a spare set on the shelf.
    • Many commercial heaters need two circuits. Give your electrician the voltage, the amps and the number of circuits before you order.
