Description
The Tulikivi D-Body is the working core of a Tulikivi soapstone sauna heater: the heater body supplied with heating elements fitted, but without a circuit board or controls. It is available in three outputs, 6.8 kW for sauna rooms of 5–9 m³, 9 kW for 8–13 m³ and 10.5 kW for 9–15 m³, each holding 60 kg of stones. A complete installation needs three further purchases: a compatible Tulikivi soapstone cladding set (the Tuisku XL covers require two bodies), a control unit (the Tulikivi Wi-Fi Complete Set or a HUUM UKU console), and 60 kg of 5–10 cm diameter sauna stones in Olivine, Vulcanite or Rounded Olivine. Single-phase connection of the 10.5 kW model is only possible with an UKU controller, and the optional KNX SIM Relay Card allows integration into a smart-home system.

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 D-Body stands on adjustable legs and is screwed to the floor with two fixings so the safety distances are maintained in use. The coupling box must be splashproof, placed no more than 500 mm above the floor and at least the safety distance from the heater. Where the body is run from a control unit not supplied by Tulikivi, the heater thermostat and overheat protection must be installed as shown in the manual. Single-phase (1N~ 230 V) connection methods differ for each controller model, and single-phase connection of the 10.5 kW body is only possible with a HUUM UKU controller.
Sauna stones
Each body takes 60 kg of sauna stones; the manual specifies olivine diabase with a diameter of less than 10 cm. Suitable stones in Olivine, Vulcanite or Rounded Olivine are sold separately. Rinse the stones and place them loosely so air can pass between them, resting on one another rather than on the heating elements. Tulikivi white cover stones are decorative and should form the top layer only; ceramic stones are prohibited, as are decorative stones from other manufacturers.
Brand
Tulikivi is the Finnish soapstone specialist, pairing electric heater technology with the heat-retaining mass of natural soapstone.
Warranty
The warranty runs for 24 months from the date of purchase or from receipt at the building site, whichever is later, and for 12 months in commercial or shared use. The heating elements are not covered by the warranty. Full warranty details are available in the Downloads tab.
Ordering note
Check the cladding set, control unit and sauna stones against the output you order before purchase. The Tuisku XL covers require two heater bodies, the 10.5 kW body connects to single phase only through a HUUM UKU controller, and the control unit must match the heater’s power rating.
