Description
The Tulikivi Tuisku XL is a large-format electric sauna heater cover clad in Finnish soapstone, built for bigger saunas, spas and gyms where a generous stone mass gives a soft and humid sauna experience and helps the sauna dry efficiently after use. The Grafia cladding is a textured soapstone, skilfully roughened through precision water cutting to achieve a sparkling, individual finish. The cover encases two Tulikivi D-Body heaters with heating elements, each available in 6.8 kW, 9 kW or 10.5 kW for a combined 13.6 kW, 18 kW or 21 kW, and both bodies are sold separately, as are the 120 kg of sauna stones and the control unit (the Tulikivi Complete Wi-Fi Control System or the HUUM UKU range, with smart-home integration available through the optional Tulikivi KNX SIM relay card). Small safety distances allow the heater to be integrated into the sauna benches.

Installation
Only one electric sauna heater may be installed in the sauna room, which must be at least 1,900 mm high. The heater stands on adjustable legs directly on the floor and should be screwed to the floor with the supplied metal fasteners so the safety distances are maintained in use. The electrical work may only be performed by a qualified electrician authorised to undertake such work, in accordance with the relevant regulations; the manual specifies H07RN-F rubber cable (PVC-insulated cable must not be used) and states that the heater’s power feed must not be connected through an earth leakage circuit breaker. The power unit may be installed no higher than 600 mm and the touch screen no higher than 1,000 mm, and the power unit for the 21 kW heater is not recommended inside the sauna room. The full instructions are in the manual in the Downloads tab.
Sauna stones
The stone compartment takes 120 kg of 5–10 cm sauna stones; olivine, vulcanite or rounded olivine are recommended, and the manual prohibits ceramic stones. Rinse the stones before use and position them loosely so that air can pass between them, resting on each other rather than on the heating elements, and always inside the stone enclosure. Tulikivi’s white decorative cover stones may be bought separately but should only make up the top layer.
Brand
Tulikivi is a Finnish soapstone specialist whose heaters and stone claddings are made in Finland.
Warranty
The warranty is valid for 24 months from the date of purchase, or from the date the product is received at the building site, whichever is later. For saunas in commercial or shared use the warranty is valid for 12 months, and the heating elements are not included in the warranty. The warranty card is available in the Downloads tab.
Ordering note
This listing is for the Tuisku XL cover only: the two heater bodies, sauna stones and control unit are sold separately. Check which Tulikivi heater bodies and output you are pairing it with before ordering, and install the assembled heater following the manual in the Downloads tab.
