Description
The Magma is Helo’s commercial electric sauna heater, built for gyms, spas, wellness centres and other large saunas in constant use. Three outputs of 18 kW, 21 kW and 26 kW cover rooms from 18 to 46 m³, each with twin element groups and an 80 kg stone capacity that sustains a pleasant steam through heavy daily use. Finished in dark graphite grey, the heater is operated through Helo’s WE50 relay box paired with a Pure or Elite controller, both sold separately, as are the sauna 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 Helo 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 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. Each of the two element groups is wired on its own supply feed, so two connection cables and fuse sets are required.
Sauna stones
Sauna stones are purchased separately; each Magma model takes approximately 80 kg.
Brand
Helo was founded in 1919 and was the first manufacturer of electric sauna heaters. Its heaters are still handcrafted in Hanko, Finland, and the company is part of the Sauna360 group.
