Description
Laine, Finnish for wave, is the most recent addition to Helo’s heater range, and its flowing black profile takes its lines from the water that inspired the name. A 62 kg stone capacity gives this compact heater an unusually soft, generous steam for its size. It can stand on the floor or be wall-mounted, with a built-in thermostat and timer keeping operation simple. This 9 kW version heats sauna rooms of 9–13 m³ and connects to a three-phase supply only; 6 kW and 8 kW versions with single-phase options are listed separately. Sauna stones are sold separately, with 10–15 cm vulcanite or olivine diabase stones recommended.

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 Helo recommends that the heater supply is not run through one; other electrical devices in the sauna room should be RCD protected.

The connection cable is heat-resistant H07RN-F (60245 IEC 66), and the installation manual in the Downloads tab and local wiring regulations must be followed.
