Narvi Slim Electric Sauna Heater
The sleek, modern design of the Narvi Slim has great potential for innovative sauna design. The Slim can be fitted with ease, either on a high base or recessed into the sauna benching. The bench collar or high base are available in the Sauna Accessories section of our site. The Narvi Slim is also a great choice as a freestanding heater for narrower sauna rooms. In order to provide to accommodate for the narrower design without compromising on Narvi’s renowned löyly, this heater has a greater width which has the added benefit of spreading the heat more evenly throughout the sauna.
This heater looks great in both modern and traditional sauna designs and comes with a separate control unit which is a stylish and practical way to accurately control the sauna temperature. This control unit can be fitted outside the sauna too. The heater is also compatible with other control units and thus is available as a standalone. However, please note that a control unit is required for this heater to function.
The addition of white cover stones to the heater will ensure an elegant, refined sauna experience. The heating elements of Narvi electric sauna heaters have an exceptionally large diameter (8.5 mm), improving the durability of the product and increasing its lifespan, as well as reducing the chance of overheating significantly.
The Slim can be safely and stylishly installed within sauna benching with the use of an installation flange. To install the Narvi Slim within raised benching, you will also require the Narvi Slim Raised Installation Base.
This heater must be installed by a qualified electrician and can be easily installed on both single phase and three phase power supplies.
