Narvi Trio Electric Sauna Heater

£ 1,617.00 GBP

Product Description

The unique and highly practical design of the new Narvi Trio electric sauna heater sets it apart from every other heater on the market. The Narvi Trio is yet another Finnish Key-flag marked sauna heater in the Narvi range. The heater combines cast stone with a steel base in order to provide a sauna steam like no other. All sauna enthusiasts know the secret to the best sauna steam (or löyly) is to have as much stone and as little metal as is possible. The Narvi Trio uses the moulded stone mass around the top of the heater to ensure that the benefits of the heaters already large stone capacity (40kg) are not lost by having a highly metallic casing. The stone mass acts like the sauna stones in further transferring heat and steam when water is added. 


The Trio also boasts exceedingly small safety distance required from combustible materials. This, coupled with the Trios unique shape, allows it to be located in small spaces in compact saunas. However, the Trios refined aesthetic means it would be equally well located taking pride of place as the centre-piece of your sauna. Like many other Narvi and Kota electric sauna heaters, the Trio is also installable within the sauna benching with the use of the stainless steel installation flange.

The two colour options, light and dark stone, suit both light and dark sauna rooms and the spectrum of wood colours. The Trio is available in 6.8kW and 9kW power options depending on the internal volume of your sauna. The heater can be sold as an e-model (without the control unit, power card and thermostat) or with the Narvi2014E integrated power card kit, allowing you the option to choose other compatible control units and power cards.

This heater can be easily installed on both single phase and three phase power supplies by a qualified electrician. To learn more about installing electrical heaters on domestic power supplies, see our "How to choose the right sauna heater" page.
