Description

About this IKI Heater

The IKI Pillar heater suits slim and tight spaces perfectly. The slim stone pillar leaves plenty of room for wider bench solutions. Free air flow through a stainless steel mesh together with large contact area between the resistors and stones enable the super-fast heating time. The large stone mass makes for a gentle and humid steam with plenty of oxygen in the air. For larger, communal saunas, the pillar is also a perfect choice of heater.

Depending on the control unit you will opt for, the heater either comes with no control unit enabling you to choose your own compatible option, or their IKI UKU Wi-Fi Controller, a remote control option with Wi-Fi capabilities (which can also be used without the Wi-Fi functionality).

About IKI Kiuas

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 onto the sides of the heater body. 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. 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.

The IKI Heater with No Control Unit

This option will enable you to connect your own control unit of choice. Please get in touch with us about compatibility of control units and we will be happy to assist.

The IKI Heater with a UKU Black Glass Wi-Fi Control Unit

A stylish black glass display on the control panel and a remote-control functionality used via a mobile application make for a winning combination.

UKU Glass Black Wi-Fi remote sauna control unit makes sauna heating very easy and comfortable. With the UKU GB you can heat your sauna on the spot or do it from your phone through mobile app. In order to use the mobile app solution, UKU GB needs to be connected to a Wi-Fi network. This control unit will also work, should you not wish to use the Wi-Fi functionality.

The control panel can be mounted to the wall or it can be surface-mounted. For surface mounting, the control panel requires a separate surface mounting frame.

Below are a few features of the UKU controller:
