Juup Gösta
Original’s power, Iivari’s steam properties.
Gösta is designed for saunas from 15 to 40 m³ and combines the efficiency of Original with the excellent sauna features of Iivari. The overall efficiency of the stove is over 73%.
Balanced stone volume and heat output
Juup Gösta’s stone cache can hold around 45-55 kg of stones, depending on the size and material of the stones. The amount of stones is precisely sized to match the heating capacity of the stove, so the stove can keep the stones hot all the time – even if you throw the stones more often.
Versatile and long-lasting stews
Gösta’s stone nest is located directly above the firebox in a stone bath. This ensures that the stones heat up quickly and that every drop of the steam water evaporates efficiently. Part of the water trickles down to the bottom of the pot and gradually evaporates, producing moist, soft and long-lasting stews. By adjusting the temperature and the amount of water in the stove, everyone can find their own preferred sauna experience.
Finnish handicraft
Each Juup artisan stove is unique and made in Finland. To ensure quality and durability, the stove is built from start to finish by the same person. Each heater has a label showing the model name, serial number and builder’s name. Juup Gösta has been awarded the Key Flag by the Finnish Association for Work, which is a symbol of Finnish manufacturing and employment.

Versatile löylys
We wanted to develop a stove that provides the best and most versatile steam. We have taken the long, moist, and soft steam of a smoke sauna as our model.
The ‘secret’ of the steam in smoke saunas lies in the way the stones are heated. The stones at the bottom get incredibly hot, while the surface stones remain relatively lukewarm throughout the sauna session. When water is poured onto the stones, it doesn’t evaporate immediately from the surface stones, but flows down to the bottom of the stone compartment where evaporation occurs. As this steam travels through the cooler stones, a condensation process begins which softens and moistens the steam.
In Juup stoves, the stones are directly above the firebox in a “stone bowl.” This allows the stones to heat up quickly and every drop of water to evaporate into the sauna. The stones at the bottom heat up first and remain hot throughout the sauna session, just like in a smoke sauna.
The stones on the surface of the stone bowl heat up slowly, allowing for the creation of different types of steam during the sauna session. The water that doesn’t evaporate upon contact with the hot stones flows down to the bottom of the bowl and evaporates gradually. This results in soft, moist and long-lasting löyly.
By adjusting the stove’s temperature and the amount of water, you can create exactly the kind of steam that you like. Crisp steam is created when you throw small amounts of water onto the hot stones on the edges frequently. If you prefer soft and moist steam, you can pour a larger amount of water on the lukewarm stones. This creates a steam bath-like löyly.

Warranty
The heater body and fireplace are constructed of 3 mm carbon steel and the fireplace has only one weld seam. This allows the stove to last from one generation to the next. The original stoves, built by Gösta Juup in the 1950s, are still in use.
Thanks to its solid and durable construction, we grant the stove a 10-year warranty in home use.
