IKI LÖYLY

for 705-1415 ft³ saunas

IKI Löyly – The Ultimate Wood-Burning Sauna Stove for Large Saunas

DESCRIPTION

The IKI Löyly wood-burning sauna stove is the largest and most powerful heater in the IKI lineup, engineered to deliver an exceptional sauna experience for large sauna rooms. With an extraordinary stone capacity of 880 lbs, this heater produces unmatched heat retention, smooth steam, and legendary Finnish löyly.

Designed for large saunas ranging from 705 to 1,415 cubic feet, the IKI Löyly exceeds the expectations of even the most demanding sauna enthusiasts. Its massive stone volume allows the heater to radiate consistent heat long after the fire has died down, ensuring a comfortable and evenly heated sauna session from start to finish.

The stove heats up in approximately one hour, thanks to the extensive contact area between the firebox and stones. As the heavy-duty spiral fire pipe heats to a glowing red, it rapidly transfers heat into the large stone mass inside the mesh-style heater. This innovative design is what makes IKI wood-burning sauna stoves renowned for their superior steam and heat distribution.

With nearly 880 lbs of sauna stones, the IKI Löyly generates powerful, long-lasting heat and rich steam that envelops the entire sauna. For a softer, more humid sauna experience, simply pour water over the sides of the heater to release gentle, enveloping steam.

Like all IKI sauna heaters, the Löyly model is handcrafted in Finland using premium stainless steel and other high-quality, durable materials. Built to meet the rigorous standards of North American customers, this wood-burning sauna stove combines authentic Finnish craftsmanship with outstanding performance and longevity.

HOW TO INSTALL AN IKI WOOD-BURNING HEATER INTO A CHIMNEY PIPE

US chimneys have a standard diameter of 6 inches, instead of 4, whereas IKI stove pipe is European standard 4 inches in diameter. This is why IKI makes a chimney adapter for easy installation.

IKI Chimney adapter

The IKI chimney adapter is made from the same durable stainless steel as rest of the heater. With the IKI chimney adapter the heater can be easily installed to a Duravent Double wall stovepipe.

CHIMNEY PIPE

IKI does not make chimney pipes for the US market but recommends using the Duravent Telescoping Double Wall Chimney for easy installation. You can order one from any major hardware store such as Home Depot.

Stove Pipe installation

ATTN! Duravent has different sizes of telescope chimneys, 6DVL-68TA, so make sure you measure your sauna room height before ordering the chimney.
