IKI Sauna Heaters

IKI-Kiuas has been providing Finnish craftmanship for sauna enthusiasts since the mid-nineties. Their electric and wood burning heaters with stainless steel mesh frames and substantial stone capacities are hand crafted in Pieksämäki, Finland by dedicated sauna heater craftsmen that have over 40 years’ experience in welding black iron and stainless steel. IKI Kiuas continuously maintains a steadfast focus on detail to provide the best possible löyly experience.

About IKI Kiuas

IKI Kiuas produced their first wood burning heater in 1996, soon after which the company IKI Kiuas Ltd. was established in 1997. The humid and soft steam characteristic of the IKI stoves is created through the large stone capacity of the electric and wood burning sauna heaters. The significant number of stones encased in a stainless-steel mesh also allows a pleasant and long-lasting steam experience with a relatively short heat up time of approximately an hour, even in the case of their larger wood burning sauna heaters.

Oxygen-Rich Steam and Durability

IKI heaters are known for their humid, soft and oxygenated steam or “löyly”, when pouring water onto the stones. A pleasant sauna experience can be achieved in any type of sauna with the right IKI heater whether large or small, commercial or domestic, wood burning or electric. The range of IKI heaters will guarantee a memorable sauna and löyly experience. IKI Kiuas is the leading manufacturer when it comes to open structured sauna heaters. IKI was the first company to manufacture sauna heaters where the stones are visible, allowing to have water thrown not only onto the top of the heater but also to the sides of the heater body.

The simplistic and durable design of IKI electric sauna heaters and wood burning stoves with huge stone capacities, encased in a mesh frame allow air to circulate freely inside the heater. This, in turn, generates oxygen rich sauna sessions. The round shape of IKI heaters eliminate premature rusting, as thermal expansion won’t cause as much stress to the metal in the heaters. The wood burning and electric heaters by IKI are durable and will last for many years if well maintained.

Energy Efficient

IKI sauna heaters are well suited for commercial saunas. Because of the large quantity of stones in the heaters, the power can be switched off every now and then between sessions. The transfer of heat from the stones is slow, allowing the sauna to maintain a higher temperature, even once the heater has been switched off.

IKI Kiuas has a selection of electric- and wood burning heaters.
