Correct connection of your Narvi electrical sauna heater in the UK

The installation and maintenance of your new Narvi electrical sauna heater must be done by a certified electrician and the electricity supply must be isolated and/or switched off from the fuse panel prior to any installation or servicing work. In accordance with European standard IEC 60364-7-703 part 703.412.5 an electrical sauna heater does not have to be connected through a Residual Current Device (RCD). This is also in accordance with BS7671:2018 part 703.411.3.3.

For reliable operation of the electric sauna heater, Narvi strongly recommends that the power supply should not be connected through a Residual Current Device (RCD). Other electrical devices in a sauna room should be connected through a Residual Current Device (RCD). Finally, the power supply cable must comply with BS7671:2018 and the instruction manual of the product and local electrical regulations must be followed. To learn more about installing electrical heaters on domestic power supplies, see our "How to choose the right sauna heater" page.
