What size sauna heater do I need?

Multiply the room’s length, width and height in feet to get cubic feet. Each square foot of glass or stone adds about 4 cubic feet of heating load, and bare log walls add about half again. Pick a heater whose rated range includes that number. The calculator above does the math.

Do electric sauna heaters need a separate control?

Most do. Each product page lists what it needs to run, and HUUM heaters 12 kW and up also need the UKU extension box. Ask us and we match the control to the heater.

Heaters ship by LTL freight on a pallet, and the driver delivers curbside. We confirm the freight cost to your address before you pay. Controls, stones and parts ship by parcel.

Installation isn’t included, but in many areas we can help arrange it through our network of independent, licensed installers. Ask when you request a quote and we’ll confirm what’s available near you.

Do you work with builders and contractors?

Yes. Trade accounts get project pricing, help with heater and control specs, and coordinated freight for multi-room jobs.
