The rule of thumb is about 1 kW of heater power per cubic meter of sauna volume. A typical 2-person sauna (around 4–5 m³) needs a 4.5–6 kW heater; larger family saunas need 8–10.5 kW. Glass doors, windows, and uninsulated walls add heat loss — size up roughly 25% if your sauna has significant glass. Use the calculator above for a quick recommendation.

Most residential sauna heaters above 6 kW require a dedicated 240V circuit installed by a licensed electrician. Smaller plug-and-play models exist, but for safety and code compliance in your area, we recommend confirming your electrical setup before ordering. Our team can review your specs with you.

Neither is better; they serve different rituals. Electric wins on convenience: push a button, sauna in under an hour, precise control. Wood-fired wins on atmosphere and independence: real fire, soft radiant heat, and no electricity needed — ideal for cottages and off-grid properties.
