Description
The HUUM Core Wall Mini Combi is a compact wall-mounted electric sauna heater with a built-in 1 kW steamer, letting you move between classic Finnish dry heat and gentler, steam-rich bathing in the same small sauna. Designed and made in Estonia, its 3.6 kW output suits rooms of 3–6 m³, its 15 kg stone capacity gives a soft, even löyly, and the 3-litre steamer tank provides roughly two hours of steam per fill. This listing is for the black finish; a white version is listed separately. The heater connects to single-phase 240 V or three-phase 400 V supplies and must be run with a HUUM UKU control console (UKU Local or UKU Wi-Fi), which is sold separately, as are the sauna stones; we recommend one 15 kg box of rounded olivine diabase stones.

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 connects to a single-phase 240 V or three-phase 400 V supply; for single-phase installations refer to the HUUM single-phase connection note in the Downloads tab. Use heat-resistant rubber-insulated cable (SIHF-JB or equivalent), never PVC-insulated cable, and crimp the cable ends. Ensure the wall structure can carry the full weight of the heater with stones, which HUUM states as up to 50 kg. When sizing the heater, add 1 m³ to the calculated room volume for each square metre of uninsulated brick, tile or glass wall. A HUUM UKU control console (UKU Local or UKU Wi-Fi, each controlling heaters up to 18 kW) is required to operate the heater and is sold separately. The steamer is wired for the UKU control system and uses a separate supply (3 × 2.5 mm² cable with a 1 × 16 A breaker); if another manufacturer’s control system is used, follow that manufacturer’s connection instructions.
Steam technology
The built-in steamer has a 3-litre tank, filled through the opening in the scent basin or with the steamer cover removed, and provides roughly two hours of steam per fill; HUUM recommends a sauna temperature of 40–50 °C for ideal humidity. Use distilled or filtered water to prevent limescale, and drain the tank after each session using the silicone drain tube and clip stored inside the heater. The steamer switches itself off automatically if the water level runs low; this model has no visual water-level gauge, so if steam stops, the tank needs refilling.
Sauna stones
The heater takes up to 15 kg of sauna stones with a diameter of 5–10 cm, sold separately; we recommend one 15 kg box of our rounded olivine diabase sauna stones. Wash the stones before first use and lay them one by one, leaving room for air to circulate and making sure no heating element remains visible through the stones.
