Designed for large and commercial saunas with daily use.

Product Description

The Narvi Ultra and Ultra Big commercial electric sauna heaters are ideal electric heaters for commercial saunas fitted in gyms, spas, hotels and wellness retreats. These heaters can also be fitted in large personal or group saunas. They are the perfect choice for demanding usage requirements, such as being active all day, every day. The Ultra combines Narvi’s exceptional löyly quality with their renowned durability to create the quintessential commercial heater. When it comes to commercial sauna heating solutions, there is no better option that the Narvi Ultra series.

The Ultra is stainless steel inside and out with some of the highest material thicknesses on the market. The elements have a market-leading thickness and grade, making this the ideal heater for frequent use where water can and should be poured over the stones.

It is certainly true that there are sauna heaters and there are sauna heaters. This is also very much the case for commercial heaters. Most modern hidden heaters and commercial heaters simply act as a heater with no stones. This creates an unpleasant löyly, is nothing like the very pleasant Finnish sauna experience and is sadly the experience that many of the British public attributes to sauna from their brief encounter with their local health club. This heater will set your sauna apart from the competition by being one of the few real Finnish electric sauna heaters in the U.K.

The Ultra series combines Narvi's renowned build quality and longevity, being with their market-leading stone capacity to provide a commercial heater that is simply like no other. Show your customers what it means to relax and enjoy a true Finnish sauna, with a genuine Finish-made, Finnish-designed commercial sauna heater.

The sauna heater is controlled from a separate control panel that can be installed where required. These control units come in the following options:
