Description
The Pillar IKI Pro Series is a commercial-grade electric sauna heater engineered for intensive daily use in leisure centres, sports facilities, spas and wellness spaces, as well as larger shared saunas. Built from high-grade stainless steel with durable AISI 309 resistors, it carries a stone mass of 140 kg to 290 kg depending on the model, producing a luxuriously soft, rich and consistent steam. Five three-phase outputs are available, 13.8 kW, 18 kW, 20.7 kW, 27 kW and 36 kW, covering sauna rooms from 15 m³ up to 50 m³. A controller is required and is not included: every model pairs with the Pro-B3 controller, and the 13.8 kW and 18 kW models are also compatible with the UKU Wi-Fi control unit. Each heater is made to order in Finland, so the order cannot be cancelled or returned once confirmed, and a sufficient quantity of sauna stones, vulcanite or olivine diabase recommended, must be purchased separately.

Installation
Installation and maintenance must be carried out by a certified electrician, with the electricity supply isolated at the fuse panel before any work begins. Under IEC 60364-7-703 and BS 7671:2018 an electric sauna heater does not have to be connected through an RCD, and for reliable operation the manufacturer recommends that the heater supply is not run through one; other electrical devices in the sauna room should be RCD protected. A local point of isolation covering all live conductors is recommended. The installation manual in the Downloads tab and local wiring regulations must be followed. The heater is connected semi-stationarily with an H07RN-F rubber cable or equivalent (PVC-insulated cable is prohibited), with the junction box no more than 400 mm above the floor; every model requires a separate controller, the Pro-B3, or the UKU Wi-Fi unit for the 13.8 kW and 18 kW models, and the model-specific wiring is set out in each heater’s installation instructions in the Downloads tab.
Sauna stones
Sauna stones are not included and must be purchased separately. IKI recommends vulcanite or olivine diabase stones under 100 mm in diameter, laid loosely so air can flow; for professional use, where the heater runs 8–18 hours a day, Kerkes ceramic stones should form at least the core of the stone fill, in the per-model quantities above. Never throw water on a cold stove, and check in professional use that the elements remain covered three times a year.
