Juup® Original

-artisan sauna stove now available!

Story about a grandfather, that couldn't find his sauna stove.

The story of Juup® heaters began in the 1950’s when graduate engineer and passionate sauna bather Gösta Juup, that used to sauna up to three times a day, needed a solution to his everyday sauna problem.

The biggest challenge for him was time, as traditional stoves required several hours of heating. Gösta also felt that the stoves on the market did not have a sufficiently wide “löyly” (steam) spectrum. Instead, each stove had its own singular type of löyly, that did not necessarily appeal to all family members.

After many years of trying to find a stove that pleased, Gösta decided to sit down by the drawing board himself.  After several prototypes and endless hours spent in the sauna, the first Juup -stove started to take form.

The result was a sauna stove, that heated the sauna in less than 20min and that had a wide range of löly types. One for every family member and friend.

Ab Juup Oy, which was founded by Göstas grandson Christian Juup in 2019, produces and designs sauna stoves that are based on Göstas original invention and design.

Warranty

The body and firebox are made of 3mm carbon steel and only have one weld seam. This allows the stove to last from one generation to the next. There are original stoves, built by Gösta Juup in the 1960s, that are still in use.

Due to its solid and durable construction, we grant the heater a 10-year warranty for home use.

Fast and economical

The Juup® Original heater challenges the operating model of traditional heaters. The stove is designed primarily to heat the sauna room and secondarily the stone nest.

Utilizing thermodynamics, the heater absorbs the cold air in the sauna room between the mantle and the firebox, from the bottom of the heater. This air heats up inside and blows out hot from the top of the heater. As a result, the sauna temperature rises by up to 10 ° C per minute, depending on the size and materials of the sauna room.

Thanks to its two hatches, the stove is very easy to ignite and only needs one nest to warm up, as well as just a few firewoods to maintain the temperature. The wood burns clean due to its large combustion space and the measured * carbon monoxide emission is only 0.11% **, which is one of the lowest values ​​on the market.

Leidenfrost effect

The Leidenfrost effect is a phenomenon that occurs when a liquid comes into contact with a hot surface. This effect is best seen when water drops are dropped on a hot frying pan. The water droplets do not evaporate immediately but remain “dancing” in the pan. This is because a thin layer of steam is formed under the droplets, which isolates the droplets from the pan and prevents it to quickly evaporate. This same phenomenon also occurs when steam is thrown into a hot stove. In reality, only part of the steam water evaporates and the rest drains to the floor.

Versatile löyly

In the Juup® Original heater, the stones are directly above the firebox in a “stone pot”. In this way, the stones heat up quickly and every single drop of the löyly-water evaporates in to the sauna. The water that does not evaporate when in contact with the hot rocks, drains down to the bottom of the pot and gradually evaporates. This results in soft, moist and a long-lasting löyly.
