Description
Manufacturing Quality
With over 11 years of experience, Eco Hearth operates as a European manufacturer focused on craftsmanship, precision, and full in-house production. We monitor every stage, from selecting raw timber to final assembly, ensuring consistent durability, refined finishing, and long-lasting performance in every sauna.
What is Thermally Modified Wood
For our saunas, we use thermally modified wood, timber that undergoes heat treatment without chemicals. The process involves slowly “baking” the wood in a kiln at 215°C for 5 days. The result:
- Increased strength and stability of the wood
- Enhanced resistance to decay and moisture
- Reduced tendency to warp or shrink
- Beautiful natural appearance preserved for decades
This ensures your sauna will look as good in 30 years as it does on the first day.
Heating Options
You can choose between a wood-burning heater, natural steam, chimney included and stones provided, or an electric heater, fast and even heating, Wi-Fi control for scheduling and temperature adjustment, also supplied with stones, whichever suits your lifestyle best.
Panoramic Window
Each sauna features a large double-glazed panoramic window that fills the interior with natural light, opens the view to your garden, and makes the space feel more open, relaxing, and connected to nature. The insulated glazing keeps the heat inside while giving the sauna its modern, airy look.
Interior Lighting
Soft lighting adds a warm, relaxing atmosphere inside the sauna and highlights the beauty of the natural wood without overpowering it.
Custom Options
As manufacturers we can expand, adjust and customize your sauna in any direction, adding terraces, covered canopies, shower areas, changing rooms, bar zones, BBQ setups, relaxation spaces or storage modules, creating the perfect layout for your property and the way you live. For a complete wellness experience you can also pair your sauna with one of our premium ice baths for contrast therapy and deeper recovery.

Wood Burning Heater
Wood-burning heater Sweden 26 kW is engineered for medium-to-large sauna rooms and features a full stone cage that surrounds the firebox with a large mass of stones. As the stones heat up, they accumulate and evenly radiate warmth, helping maintain a stable sauna microclimate with optimal temperature and humidity.
The welded steel firebox and dual S-shaped flue channels ensure efficient heating: stones warm both directly through the 8 mm top plate and from secondary flames along the sides. The durable upper plate is designed to withstand extremely high temperatures and acidic environments, ensuring long-term performance.
An external firebox extension (20 cm) allows convenient wood loading from an adjacent room. The removable decorative frame makes wall integration easy and clean, while the reversible glass door (left/right mounting) enhances installation flexibility. All exterior surfaces are coated with heat-resistant silicone enamel.
The heater warms the sauna to 100–110 °C in about 30–40 minutes with minimal wood consumption. Its compact structure suits various sauna layouts, and maintenance requires only periodic cleaning every 2–4 weeks.
A practical, durable and efficient choice for traditional sauna lovers seeking strong heat output and long-lasting performance.
