Collection: Sauna Heaters(22)

Work on roughly 1kW per cubic metre of cabin volume. A compact two-person sauna usually needs around 6kW and a family cabin 8–9kW. Glass fronts and uninsulated walls push that up, so size generously. See our sauna range for volumes.

Electric heats on a timer and controls precisely, which suits weeknight use and indoor cabins. Wood-fired gives the crackle, the aroma and a softer löyly, and needs no supply at all. We stock Harvia across both, from the Cilindro to the Legend.

Yes. Sauna heaters draw far more than a standard socket circuit and must be wired to a dedicated supply by a qualified electrician. Higher-output models may need a three-phase supply, so check the specification against your consumer unit first.

Enough to cover the elements or firebox completely, typically 15–20kg on a domestic heater. The stones store the heat that makes löyly possible, so rinse them before use, stack them loosely for airflow and replace any that crack.

Most of our cabins take either type, but wood-fired needs a flue route, clear roof clearance and a heat shield behind the stove. Check the model specification or ask us first, and we will confirm the fit for your cabin.
