Electric vs. wood-burning sauna heaters
This is the biggest decision after the sauna itself, and it changes the experience more than any option on the list. Electric is convenience: press a button, sauna in 45 minutes. Wood is ritual: light a fire, tend it, and earn a deeper kind of quiet. Both make identical heat. Here's the full picture, prices included.
The experience difference
An electric heater is an appliance — reliable, precise, on a timer if you like (several models offer Wi-Fi control, so the sauna is hot when you get home). A wood stove is a practice: fifteen minutes of fire-building, the crackle through the session, löyly steam off stones heated by flame. Neither is better; they're different hobbies. Be honest about which one you'll actually do on a Tuesday in February — the best heater is the one that gets used.

Installation and operating cost
Electric needs a dedicated 240V circuit from a licensed electrician (commonly a few hundred dollars; more if your panel is distant — details in our site prep guide). Running cost is modest: a 6KW heater for a 90-minute session works out to roughly a dollar of electricity at typical rates. Wood needs no wiring at all — the whole system works in a blackout, at an off-grid cabin, anywhere. Fuel is firewood you buy or cut; figure a few splits per session.
Sizing: match kilowatts to cubic feet
Heater wattage is sized to the sauna's interior volume — undersized heaters run forever and never satisfy. Rough guide from the manufacturer's specs: the Harmony and MiniPOD want 6KW; the Serenity 6–7.5KW; the Tranquility and Elation 7.5–9KW; the big Georgian cabin 6–9KW depending on layout. Every product page on this site lists its recommended size, and we confirm the match on every quote.
Which saunas take which
All our outdoor models take electric. Wood stoves fit the Serenity, Tranquility, Elation, MiniPOD, and Georgian cabin. The Harmony, Luna, Palmer, Granby, and the indoor Element are electric-only. One practical note: order the heater with the sauna — bundled orders cross the border duty-free, while heater-only orders can attract import tariffs.
The decision in three questions
1. Is the sauna near your house with easy panel access? Electric's convenience is compelling. 2. Is it at a cottage, off-grid, or far from the panel? Wood saves the electrician bill entirely. 3. Do you want sauna to be effortless or ceremonial? That's the real question, and only you can answer it. All heaters we sell are UL-listed or properly certified either way — tell us your pick and we'll spec the right size.
