Harvia sauna heaters

Start with your sauna’s volume and compare it with the listed room range. The 2.9kW Delta Combi covers 1.5–4m³. The Wall SW45 and SW45E are both 4.5kW models listed for 3–6m³, while the 6kW SW60E covers 5–8m³. The 8kW Wall entries cover 7–12m³.

For larger rooms, the 12kW Hidden Heater entries cover 12–17m³. The 36kW Qube Pro is listed for 40–75m³. Wood-burning choices have their own ranges: the Legend 150 SL covers 6–13m³, and the Pro 20 SL covers 8–20m³. Use these model-specific figures when you build your shortlist.

Check the control details before you compare prices. The Wall SW45E starts at £455 and needs a separate control unit, sold separately. The SW45 starts at £669.63 and has built-in illuminated switches. The Cilindro PC90XE starts at £1,195 with a digital control panel included.

Check the phase field too. The Cilindro Plus Spot is listed as three-phase, while the PC90XE is single-phase. Both are 9kW models for 8–14m³.

The listings also include the Onni Onyx One infrared home sauna and Olympus Indoor Sauna. Keep those entries distinct from individual heaters when comparing starting prices.
