The Narvi Peak offers a top-class spa experience. The Peak heater is a Finnish-made commercial grade electric sauna heater. It provides a high-class spa experience with a stylish look and large stone capacity. This floor-standing sauna heater model has a round shape, which allows for different placement options within the sauna.  

The Narvi Peak is designed to endure demanding conditions and heavy use. It is an excellent electric heater choice for spas, community saunas, gyms as well as larger private saunas.

Product Disclaimers

All Narvi sauna heaters are CE tested and bear the Finnish Key Flag Symbol. This is awarded to sauna heaters that are made and designed in Finland, where over 95% or more of the production must be within Finland itself. There are many brands that claim to be made in Finland but are actually made in the Far East or Russia and merely assembled or labelled in Finland. Watch out for these symbols as a mark of an authentic, Finnish-made, safe, quality product:

As part of Finnmark Sauna's Endurance Ethos, we only deal in products that are market leaders in quality. We commit ourselves to search exhaustively for the highest quality authentic Finnish sauna products.

Please note, we recommend that sauna heaters should be installed by a suitably qualified electrician/builder/fitter. Finnmark Limited accepts no liability for loss or injury caused by the incorrect installation or misuse of your sauna heater. Please Contact Us if you require information on our recommended fitters.

Please note: All of our Narvi commercial electric heaters above 12kW are made to order, so once you receive an order confirmation from us, Narvi will start to custom-produce your heater(s) for you in Finland, and your order cannot be cancelled or returned any longer. We suggest that you make sure your design specifications and all necessary electrical and wood-burning provisions are finalised and confirmed with your designers, architect, engineers and electricians before placing your order with us.
